摘要
Abstract
Bis(trichlormethyl)carbonate as the phosgene substitute in the preparation of 4,4′-diphenylmethane diisocyanate is introduced. The reaction is carried out at room temperature for 2 hours under the stoichiometric ratio of substrates. Besides,the influence of PH value on the yields of products is discussed,fmding optimum PH within 11~12.关键词
