  • Benzyl Chloride)
    Screening Assessment for the Challenge Benzene, (chloromethyl)- (Benzyl chloride) Chemical Abstracts Service Registry Number 100-44-7 Environment Canada Health Canada November 2009 Screening Assessment CAS RN 100-44-7 Synopsis Pursuant to section 74 of the Canadian Environmental Protection Act, 1999 (CEPA 1999), the Ministers of the Environment and of Health have conducted a screening assessment of benzene, (chloromethyl)-, also known as benzyl chloride, Chemical Abstracts Service Registry Number 100-44-7. This substance was identified in the categorization of the Domestic Substances List (DSL) as a high priority for action under the Challenge. Benzyl chloride was identified as presenting greatest potential for exposure of individuals in Canada and had been classified by other agencies on the basis of carcinogenicity and genotoxicity. Although the substance met the categorization criteria for persistence, it did not meet the criteria for bioaccumulation potential or inherent toxicity to aquatic organisms; therefore, the focus of this assessment relates primarily to human health aspects. According to data submitted in response to a Notice issued under section 71 of the Act, no persons in Canada reported manufacturing benzyl chloride in a quantity greater than or equal to the reporting threshold of 100 kg for the 2006 calendar year. However, it was reported that 100 000–1 000 000 kg were imported into Canada in that year. The response to the section 71 notice indicated that benzyl chloride is mainly used in Canada as a chemical intermediate for the synthesis of quaternary ammonium compounds, which are used primarily as hard surface sanitizers, corrosion inhibitors, fungicides in industrial cleaners and bactericides in surfactants in household and personal care products.

The rate was found to be constant independently of pH. It was also found that the nucleophilic reagents such as piperidine and thiophenol have no appreciable effect on the hydrolysis rate and that the rate decreases with increase of chloride ion concentra­ tion in solution. On the basis of these results together with those on the chlorine exchange reported in the foregoing paper, the mechanism of the hydrolysis is discussed. Introduction In the foregoing paper, the chlorine exchange of benzotrichloride with aqueous chloride solution was studied!). The hydrolysis of benzotrichloride is now investigated under the same experimental condition as those in the exchange reaction to elucidate the mechanism. § 1. Experimental The reaction was carried out in the same way as in the case of benzal chloride2l. The purification of benzotrichloride has been described in the foregoing paperll.
