제조 및 합성 방법

생산 방법

The oxidation of lowvalency organophosphorus compounds is important mainly in the case of the thiophosphonic acid chlorides. This method is used in the production of methylphosphonic acid dichloride by reaction of methyldichlorophosphine with sulfuryl chloride or chlorosulfuric acid. Elemental sulfur reacts with MePCl2 in the presence of catalytic quantities of tetraalkylphosphonium salts to form methylthiophosphonic acid dichloride.

Special ReportsOrganization for the Prohibition of Chemical WeaponsConvention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and Their Destruction. Available from http://www.opcw.org/docs/cwc_eng.pdf as of May 1, 2007. The Chemical Weapons Convention (CWC) is an international treaty which bans the development, production, stockpiling, and transfer or use of chemical weapons. The Convention mandates the destruction and prohibition of chemical weapons and related facilities and provides for restrictions on international trade in toxic chemicals and precursors.
Reactivity AlertsWater-Reactive
Reactivity ProfileMETHYL PHOSPHONIC DICHLORIDE is incompatible with water, strong oxidizing agents, alcohols, bases (including amines). May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
소화Keep unnecessary people awayisolate hazard area and deny entry. Stay upwindkeep out of low areas. Ventilate closed spaces before entering them. Wear positive pressure breathing apparatus and special protective clothing.
누출 비상 조치· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.· Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.
응급 처치Warning: Methyl phosphonic dichloride is a strong irritant.General First Aid:
노출 관리 및 개인 보호· Wear positive pressure self-contained breathing apparatus (SCBA).TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
소화 절차If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use dry chemical, dry sand, or carbon dioxide. Do not use water on material itself. If large quantities of combustibles are involved, use water in flooding quantities as spray and fog. Use water spray to knock-down vapors. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
보관 조건Prior to working with this chemical you should be trained on its proper handling and storage. Store in tightly closed containers in a cool, well ventilated area. Sources of ignition such as smoking and open flames are prohibited where this chemical is handled, used, or stored. Use only non-sparking tools and equipment, especially when opening and closing containers of this chemical. Wherever this chemical is used, handled, manufactured, or stored, use explosion-proof electrical equipment and fittings.
정리 방법Evacuate persons not wearing protective equipment from area of spill or leak until clean-up is complete. Remove all ignition sources. Do not breathe vapors. Do not get water inside containerstop leak if you can do so without risk. Do not touch spilled material. Use water spray to reduce vapors but do not put water on leak or spill area. Keep combustibles (wood, paper, oil, etc) away from spilled material. Dike spill for later disposaldo not apply water unless directed to do so. Clean up only under supervision of an expert. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area after clean-up is complete. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations. If employees are required to clean-up spills, they must be properly trained and equipped. OSHA 1910.120(q) may be applicable
비화재 누출 대응Excerpt from ERG Guide 137 [Substances - Water-Reactive - Corrosive]:
처리 방법SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal, aquatic, and plant lifeand conformance with environmental and public health regulations.
Preventive MeasuresIf material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard. Use water spray to knock-down vapors.

유해 작용Dermatotoxin - Skin burns.
Medical SurveillanceLung function tests /SRP: due to risk of pulmonary edema/.. Consider chest x-ray following acute overexposure.
Human Toxicity Excerpts/SIGNS AND SYMPTOMS/ Short Term Exposure: Poisonous if inhaled or swallowed. Highly corrosive. Contact causes severe burns to skin and eyes. May cause permanent damage. Inhalation causes irritation. High levels of exposure can cause pulmonary edema, a medical emergency that can be delayed for several hours. This can cause death. Long Term Exposure: May cause lung irritation or bronchitis to develop.
Non-Human Toxicity Excerpts/LABORATORY ANIMALS: Acute Exposure/ Acute inhalation toxicities were determined in rats and guinea-pigs for ... methyl-phosphonic-dichloride ... (MPD), and the products of /its/ neutralization by ammonia. Female rats and male guinea-pigs were exposed for 4 hours to vapors of the above compounds in varying concentrations. Animals were observed and deaths were recorded up to 14 days postexposure. Median lethal concentrations (LC50) were computed. ... LC50s of MPD and neutralization products were 26.1 and 328.8 umoles per mole in rats. Hydrolysis was about 75 percent. MPD exposure produced numerous signs of irritation and caused death within 4 daysneutralization products produced no irritation but caused death within 1 day. ...
Antidote and Emergency TreatmentBasic 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 ... . Monitor for shock and treat if necessary ... . Anticipate seizures 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 ... . If product was ingested, protect yourself from contact with vomitus as it may cause burns. /Phosphorus 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. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . 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. Watch for signs of fluid overload ... . Treat seizures with diazepam or lorazepam ... . Monitor for signs of hypoglycemia (decreased LOC, tachycardia, pallor, dilated pupils, diaphoresis, and/or dextrose stick or glucometer readings below 50 mg/dl) and administer 50% dextrose if necessary. Draw blood sample before administration ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Phosphorus and related compounds/
