Vinyl chloride aswell accepted as vinyl chloride, is a acclimated in the polymer actinic important monomer, acquired from ethylene or acetylene. For colorless, simple liquefied, baking point of -13.9 ° C, the analytical temperature of 142 ° C, analytical burden of 5.22MPa. Vinyl chloride is a baneful substance, alarmist blight with abiding assimilation acknowledgment to vinyl chloride. Form an atomic admixture with air, atomic absolute of 4% to 22% (by volume), added acceptable beneath burden to explode, closed accumulator alembic have to Blanketing, and should add a baby bulk of polymerization inhibitor. The astute toxicity of analgesic effects; Abiding acknowledgment can could could cause chloride disease. Astute poisoning: balmy contagion suffered from dizziness, lightheadedness, drowsiness, amazing gait; Severe contagion can action coma, amusement and even death. Derma acquaintance with vinyl chloride aqueous may could could cause erythema, edema or necrosis. Chronic poisoning: manifestations of fretfulness syndrome, hepatomegaly, aberrant alarmist function, digestive dysfunction, Raynaud's abnormality and acral osteolytic disease. The derma may arise dry, chapped, scaling, eczema.
Vinyl chloride is acquired by the top temperature pyrolysis of a petroleum hydrocarbon alloyed gas of acetylene and ethylene (approximately equimolar ratio) as raw material, calm through the agitator bed of mercuric chloride, hydrogen chloride careful acetylene adduct to aftermath vinyl chloride and hydrogen chloride. Afterwards break trichlorethylene, ethylene-containing balance gas, alloyed with chlorine, the acknowledgment generates dichloroethane. Separated and antiseptic afterwards dichloroethane, thermal arise to vinyl chloride and hydrogen chloride. Hydrogen chloride recycling for the accession of acetylene in the gas mixture. Store in a cool, aerial warehouse. Keep abroad from blaze and heat. Accumulator temperature should not beat 30 ℃. With oxidants should be stored alone and abstain bond reservoir. The explosion-proof lighting, blast facilities. Prohibit the use of automated accessories and accoutrement simple to aftermath sparks. Accumulator areas should be able with discharge acknowledgment equipment. Confined operation, abounding ventilation. The abettor have to go through specialized training, austere adherence to rules. Proposed operators abrasion clarify respirators (half-mask), cutting actinic careful assurance glasses, cutting blaze careful clothing, abrasion actinic aggressive gloves. Abroad from fire, calefaction source, abode smoking.
