产品名称	磷钨酸水合物, AR
英文名称	Phosphotungstic acid
CAS编号	12067-99-1
产品熔点	89ºC
精确质量	2881.20000
PSA	702.09000
外观性状	灰白色结晶粉末
溶解性	PRACTICAL 不溶
稳定性	易潮解。与碱共沸时分解为磷酸盐和钨酸盐。含水量一般是在9～17分子之间。加氯水后加热很容易使还原产物再被氧化。虽然磷钨酸在水中的溶解度很大，但它可以被乙醚完全从水溶液中萃取出来。它和乙醚形成一比重很大的液层，这是一个乙醚与磷钨酸的复合物，既不溶于乙醚也不溶于水，因而当以过量乙醚来萃取水溶液时形成了三个液层。除了极易溶于水和乙醚之外，磷钨酸还易溶于低元醇和酯中。
储存条件	常温密闭，阴凉通风干燥

Section 3 - HAZARDS IDENTIFICATION

EMERGENCY OVERVIEW
Causes burns.Corrosive.
Potential Health Effects
Eye:
Causes eye burns. Contact may cause ulceration of the conjunctiva and cornea.
Skin:
Causes skin burns. May cause skin rash (in milder cases), and cold and clammy skin with cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes gastrointestinal tract burns. May cause perforation of the digestive tract. Causes severe pain, nausea, vomiting, diarrhea, and shock.
May cause systemic effects.
Inhalation:
Causes chemical burns to the respiratory tract. Aspiration may lead to pulmonary edema. May cause systemic effects.
Chronic:
Effects may be delayed.

Section 4 - FIRST AID MEASURES
Eyes: Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed. Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Destroy contaminated shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh air immediately. If breathing is difficult, give oxygen. Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device.
Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or appropriate foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective Equipment section. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Minimize dust generation and accumulation.
Keep container tightly closed. Do not get on skin or in eyes. Do not ingest or inhale. Discard contaminated shoes.
Storage:
Keep away from heat and flame. Keep refrigerated. (Store below 4C/39F.) Keep container closed when not in use. Corrosives area.
Store in a cool, dry area away from incompatible substances.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low.
