由醇催化转化为长链氯代烷

Catalytic Conversion of Alcohol to Corresponding Alkyl Chlorides

采用 N,N-二甲基甲酰胺和正十二烷基三甲基氯化铵为催化剂 ,将正辛醇、正十二醇和正十六醇分别与氯化亚砜反应 ,得到 1-氯正辛烷、1-氯正十二烷和 1-氯正十六烷 ,收率比不用催化剂提高 10 %～ 2 0 % ,反应速度加快 .产物用红外光谱和质子磁共振谱进行了结构表征 .

chloro\|octane, 1\|chloro\|dedocane and 1\|chloro\|hexadecane are synthesized from the corresponding alcohols. The reactions are catalyzed by N, N\|dimethyl formamide and dodecyltrimethyl animonium chloride, not only the reaction time has been reduced, but also the yield improved from 10%~20%.
