摘要:选择了10个含磺酸基团的化合物作为相转移催化剂,测定其在H_2O/CH_2COOH-CH_3COONa/ClCH_2Cl体系中的亲电偶合反应速率常数。对比无催化剂存在时的动力学数据,证明这类化合物是有效的亲电取代反应的相转移催化剂。通过动力学数据测定,证明催化性能与催化剂及离子对结构中的亲水、亲油基团存在着定量关系。
Ten sulfo-group containing compound were tested whether they could be used as the phase transfer catalyst (PT CS) for the electrophilic substitution in the solution of H2O/CH3COONa-CH3COOH/ClCH2Cl by measuring the coupling reaction rate constant.When compared with the kinetic data of the reaction without PTCS,these compounds proved to be effective catalysts for the electrophilic reaction.According to the kinetic investigation,their catalytic power is quantitatively related to the presence of the hydrophilic and oleophilicgroup in the structure of the catalyst and the ion pair.
