The known explanations for the catalytic action of hydrogen chloride in thermal degradation of PVC are discussed. It has been shown that initiation of the catalysed reaction occurs without participation of double bonds, due to the reaction of HCl with the normal monomer unit. The existence of ...
The genotoxins ethyl chloride (EtCl) and methyl chloride (MeCl) were generated during the preparation of the hydrochloride salts of two tertiary amines in the presence of ethanol and methanol, respectively. In EtOH five batches of a tertiary amine hydrochloride were prepared on 0.318 kg scale us...
