Reactive GroupAnhydrides
Reactivity AlertsWater-Reactive
Reactivity Profile · 1 件

PYROSULFURYL CHLORIDE is strongly acidic. Incompatible with strong oxidizing agents, alcohols, amines and other bases. 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]. Red and white forms of phosphorus react vigorously with the chloride.

化学的性質

化学的特性Colorless, very mobile liquid; characteristic odor; fumes faintly in moist air and becomes cloudy because of the separation of sulfuric acid.

/GUIDE 137: SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Fire or Explosion: EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Flammable/toxic gases may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. Substance may be transported in a molten form.

/GUIDE 137: SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Health: CORROSIVE and/or TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire will produce irritating, corrosive and/or toxic gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Contact with molten substance may cause severe burns to skin and eyes. Runoff from fire control or dilution water may cause pollution.

/GUIDE 137: SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Public Safety: CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover. As an immediate precautionary measure, isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids. Keep unauthorized personnel away. Stay upwind. Keep out of low areas. Ventilate enclosed areas.

/GUIDE 137: SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.

· 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.

General First Aid:

Exposure Control and Personal Protection· Wear positive pressure self-contained breathing apparatus (SCBA).
Cleanup Methods · 2 件

Spills of hazardous chemicals (such as inorganic sulfur acids, oleums of strength 35 to 65%, liquid sulfur trioxide, or chlorosulfonic acid) can be treated with high molecular weight polyacrylamide, polymethyl methacrylate or a blend of polyacrylamides. Each forms a polymer skin over the liquid surface, suppressing the fume & allowing access to the spill so that cleanup can be done in a controlled manner. Polyacrylamide variant DP 1916 is best treatment for chlorosulfonic acid & oleum 20. Polycarbonate granules used in a layer approx 80 mm thick topped off with Sorboil (an absorbent clay) is best treatment for diked spills of oleums of all strengths & liq sulfur trioxide. The acid beneath the skin is best recovered by pumping. Unconfined spills of sulfur trioxide & oleums of all strengths can be treated with excess anhydrous sodium sulfate which forms a concrete-like residue that can be sprayed with water within 1 hour, dissolving it slowly. Expanded perlite, if contained in degradable bags, will effectively absorb & contain sulfur acids. Fumes of oleum 65% arising from spillage of 80 to 750 kg can be killed within 4 to 13 min. Asphalt or concrete is slightly affected.

Human Toxicity Excerpts · 3 件

SYMPTOMATOLOGY (...INGESTION OR SKIN CONTACT): 1. CORROSION OF MUCOUS MEMBRANES OF MOUTH, THROAT AND ESOPHAGUS, WITH IMMEDIATE PAIN AND DYSPHAGIA. NECROTIC AREAS...GRAYISH WHITE BUT SOON ACQUIRE A BLACKISH DISCOLORATION (YELLOW IN CASE OF NITRIC ACID) & SOMETIMES SHRUNKEN OR WRINKLED TEXTURE... 2. EPIGASTRIC PAIN...MAY BE ASSOC WITH NAUSEA & VOMITING... AT TIMES, GASTRIC HEMORRHAGE MAY BE INTENSE, AND VOMITUS THEN CONTAINS FRESH BLOOD. PROFOUND THIRST. 3. ULCERATION OF ALL MEMBRANES AND TISSUES WITH WHICH THE ACID COMES IN CONTACT. AFTER THE INGESTION OF CONCN MINERAL ACID, THIS CORROSION MAY LEAD WITHIN A FEW HR OR A FEW DAYS TO GASTRIC PERFORATION AND PERITONITIS. 4. CIRCULATORY COLLAPSE WITH CLAMMY SKIN, WEAK & RAPID PULSE, SHALLOW RESP, AND SCANTY URINE. CIRCULATORY SHOCK IS OFTEN IMMEDIATE CAUSE OF DEATH. /ACIDS/

SYMPTOMATOLOGY.../INGESTION/: 6. LATE ESOPHAGEAL, GASTRIC & PYLORIC STRICTURES & STENOSES, WHICH MAY REQUIRE MAJOR SURGICAL REPAIR, SHOULD BE ANTICIPATED. SIGNS OF OBSTRUCTION COMMONLY APPEAR WITHIN A FEW WK BUT MAY BE DELAYED FOR MONTHS AND EVEN YEARS. PERMANENT SCARS MAY ALSO APPEAR IN THE CORNEA, SKIN AND OROPHARYNX. 7. UNCORRECTED CIRCULATORY COLLAPSE OF SEVERAL HR...MAY LEAD TO RENAL FAILURE & ISCHEMIC LESIONS IN LIVER & HEART. /ACIDS/

Toxic & corrosive to tissue.
