독성 요약IDENTIFICATION AND USE: Thionyl chloride is a colorless to pale yellow or reddish liquid. Thionyl chloride is an industrially produced liquid used to make acyl chlorides and to synthesize pharmaceuticals including drugs and vitamins. It is used to make dyes, to prepare organic chlorine compounds, as a solvent in the production of herbicides, and as an electrolyte in lithium batteries. Thionyl chloride is also used to prepare polyacrylate-type engineering thermoplastics made from iso- and tere-phthaloyl chlorides. It is required in the manufacture of methylphosphonic dichloride, a key precursor for the nerve gas Sarin. HUMAN STUDIES: Potential symptoms of overexposure are irritation of eyes, skin, mucous membranes, as well as eye and skin burns. Symptoms of exposure range from mild irritation to death and include dyspnea, burns, pulmonary edema, and inflammation. Cases of thionyl chloride-induced lung injury have been noted. ANIMAL STUDIES: A 20-min exposure to 17.5 ppm proved fatal to cats. Male rats were exposed to 99% pure thionyl chloride in a whole-body inhalation chamber. Two of five males died at 1239 ppm, three of five died at 1509 ppm, and four of five died at 1989 ppm. All deaths occurred within 48 hours of exposure. Severe lung irritation and edema were reported as the cause of death.

Human Toxicity Excerpts/SIGNS AND SYMPTOMS/ Potential symptoms of overexposure are irritation of eyes, skin, mucous membraneseye, skin burns./SIGNS AND SYMPTOMS/ Symptoms of exposure range from mild irritation to death and include dyspnea, burns, pulmonary edema, and inflammation./CASE REPORTS/ ... A case /was reported/ of a pharmaceutical production plant worker exposed for two minutes to an unknown amount of thionyl chloride vapor during repair of a vent pipe. The worker experienced burning of the eyes, upper airway, and chest followed by feelings of suffocation. He began coughing with expulsion of blood. He was hospitalized ... with cough, sero-mucosal excretion, pharyngeal and chest burning. His respiratory function test showed insufficient ventilation and examination revealed vesicular murmur with wheezing at end of expiration. He was diagnosed with acute asthmatic tracheal bronchitis, was treated with bronchodilators and antibiotics, and recovered./CASE REPORTS/ /An/ employee suffered CNS effects after an acute exposure to an unknown concentration of what was believed to be thionyl chloride. The employee was not wearing any respiratory protection, inhaled 2-3 breaths of thionyl chloride vapor, and began suffering from rhinitis, lacrimation, sore throat, and coughing. The employee also exhibited signs of impaired hand-eye coordination, memory, judgment, and slurred speech. These clinical signs had improved six hours post exposure and no symptoms were present 72 hours post exposure.For more Human Toxicity Excerpts (Complete) data for Thionyl chloride (6 total), please visit the HSDB record page.
Artificial Pollution SourcesThionyl chloride's production and use in the manufacture of pesticides, engineering plastics, as a chlorinating agent, catalyst(1) and in the synthesis of various nerve agents(2) may result in its release to the environment through various waste streams(SRC).
Non-Human Toxicity Excerpts/LABORATORY ANIMALS: Acute Exposure/ /A study/ exposed male Fischer 344 rats to 99% pure thionyl chloride in a 60-liter whole-body inhalation chamber for one hour and observed the animals for at least two weeks post exposure. Analytical concentrations were measured by IR analysis. Moisture from the rats increased the humidity of the chamber to around 50% and caused almost complete hydrolysis of thionyl chloride to a mixture of sulfur dioxide and hydrogen chloride, and rats were exposed to this mixture more than to thionyl chloride. Exposure concentrations were reported as the mixture of sulfur dioxide and hydrogen chloride concentrations (906, 1080, 1239, 1509, or 1983 ppm). Five animals were exposed per group and no deaths were reported at 906 or 1080 ppm of the mixture. Two of five males died at 1239 ppm, three of five died at 1509 ppm, and four of five died at 1989 ppm of the mixture. All deaths occurred within 48 hours of exposure. Examination of the animals revealed mild to moderate multifocal congestion and alveolar damage. Severe lung irritation and edema were reported as the cause of death. The BMCL05 /benchmark concentration, 95% lower confidence limit with 5% response/ and BMC01 /benchmark concentration with 1% response/ were 663 and 830 ppm, respectively./LABORATORY ANIMALS: Acute Exposure/ ... Five male and five female Wistar rats /were exposed/ in an OECD Guideline study to 71, 407, 769, 2121, or 3441 ppm of thionyl chloride vapor for one hour and observed ... for 14 days post exposure. The thionyl chloride used for the study was reported to be 99.8% pure, and rats were exposed head/nose only in a chamber 30 x 28 cm that prevented expired air from mixing with test atmosphere. Analytical concentration was determined using spectrophotometry. The LC50 was calculated to be 1277 ppm. Four of five males and four of five females died at 2121 ppm, and five of five males and four of five females died at 3441 ppm prior to sacrifice. Prior to death, labored breathing was observed in the animals. The author noted opacity of cornea, lung distention, necrotic changes in the nose, and pulmonary edema in the animals that died. The BMCL05 /benchmark concentration, 95% lower confidence limit with 5% response/ and BMC01 /benchmark concentration with 1% response/ were 507 and 671 ppm, respectively./LABORATORY ANIMALS: Acute Exposure/ ... 6 male and 6 female Wistar rats /were exposed/ to 196, 371, 593, 954, or 1241 ppm to 99.9% pure (a.i.) thionyl chloride vapor in a nose-only chamber for one hour and observed ... 14 days post exposure. Gas chromatography was used to analyze thionyl chloride during exposure. The LC50 was 736 ppm for males and females combined. No deaths were recorded in the 196 or 371 ppm exposure groups. Five of six males and two of six females died at 593 ppm. Five of six males and two of six females died at 954 ppm. Six of six males and four of six females died at 1241 ppm. Prior to death, audible respiration was observed. Hyperinflation of the lungs, perinasal and periocular encrustation were noted in some of the animals that died in the 954 and 1241 ppm exposure groups. One control male rat died during exposure and it was thought to be due to incorrect positioning in the chamber. The BMCL05 BMCL05 /benchmark concentration, 95% lower confidence limit with 5% response/ and BMC01 BMC01 /benchmark concentration with 1% response/ were 193 and 222 ppm, respectively./LABORATORY ANIMALS: Acute Exposure/ A 20-min exposure to 17.5 ppm is said to have proved fatal to cats.

Probable Routes of Human ExposureAccording to the 2016 TSCA Inventory Update Reporting data, 4 reporting facilities estimate the number of persons reasonably likely to be exposed in the manufacturing, processing, or use of thionyl chloride in the United States may be as low as 10-25 workers up to the range of 100-500 workers per plantthe data may be greatly underestimated due to confidential business information (CBI) or unknown values(1).NIOSH (NOES Survey 1981-1983) has statistically estimated that 7082 workers (1223 of these are female) were potentially exposed to thionyl chloride in the US(1).
Antidote and Emergency TreatmentImmediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Sulfur and related compounds/Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Anticipate seizures and treat if necessary ... . Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . Cover skin burns with dry sterile dressings after decontamination ... . /Sulfur and related compounds/Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Early intubation at the first sign of upper airway obstruction may be necessary. Positive-pressure ventilation techniques with a bag-valve-mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Consider administering a beta agonist such as albuterol for severe bronchospasm ... . Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if patient is hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Treat seizures with diazepam (Valium) or lorazepam (Ativan) ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Sulfur and related compounds/If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water or milk. Do not induce vomiting. Medical observation is recommended for 24-48 hr after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor of authorized paramedic may consider administering a corticosteroid spray.
