Vinyl Chloride General information
ثبت نشده
چکیده
Toxic by all routes of exposure – inhalation, ingestion, skin contact Carcinogenic in humans Inhalation of vinyl chloride causes coughing, wheezing and breathlessness, headache, ataxia, drowsiness and coma Ingestion of vinyl chloride causes nausea, vomiting, diarrhoea, abdominal pain, and haematemesis may occur. Skin contact causes irritation, pain, burns and contact dermatitis. Rapid evaporation of compressed gas may produce local frostbite. Ocular exposure to the gas causes moderate irritation and pain. Exposure to liquid may possibly cause frostbite and corneal injury.

Highly active nickel catalysts for the isomerization of unactivated vinyl cyclopropanes to cyclopentenes.
General information. N-Heterocyclic carbene ligands and their corresponding salts (e.g., IMes and IMesBF 4 , IPr and IPrBF 4) were prepared as previously reported or under slightly modified procedures and handled in a N 2 filled drybox or using standard Schlenk techniques.
متن کاملEffect of some additives on degradation of poly (vinyl chloride- co- vinyl
The thermal decomposition of 86 % vinyl chloride 14 % vinyl acetate copolymer wasstudied by the conductometry technique in the presence of nitrogen. The kinetics of stability andthermal degradation of vinyl chloride- co- vinyl acetate (PVC- co- PVAc) copolymer withcopper, copper oxide and tricalcium dicitrate (st) were investigated at various temperatures (150-180 oC ) in solution. The rate coe...
متن کاملNeeds for public health intervention and needs for new research on vinyl halides and their polymers: a public policy perspective.
Consideration of needs for public health interventions and new research requires comparative assessments of the health benefits that are likely to result from alternative uses of limited regulatory and technical resources. This paper briefly examines regulatory and research priorities in the light of recent information on the carcinogenic hazards of vinyl chloride and alkyl and vinyl halides re...
متن کاملCopolymerization of Vinyl Chloride by Organometallic Compounds
ABSTRACT The copolymerizations of vinyl chloride with o-olefin or acrylic compounds were investigated with organometallic compounds as catalysts. In general, organoaluminium compounds need to be treated with a complexing agent such as tetrahydrofuran prior to use. Otherwise the former reacts with polyvinyl chloride and loses its activity. The copolymer of vinyl chloride and propylene was thus o...
متن کاملEfficient and general synthesis of oxazino[4,3-a]indoles by cascade addition-cyclization reactions of (1H-indol-2-yl)methanols and vinyl sulfonium salts.
An efficient and general approach to oxazino[4,3-a]indole architectures is described. The addition-cyclization cascade of (1H-indol-2-yl)methanols with vinyl sulfonium salts affords oxazino[4,3-a]indole derivatives in high yields.
