摘要 用Michaelis-Becker反应合成了8个烷基膦酸二正己酯;并改进方法,利用相转移催化技术合成了4个高位阻烷基膦酸二正己酯;同时还观察到产物折光率的加和性及随温度变化的规律。 Di-n-hexyl alkylphosphonates were prepared with the Michaelis-Becker reaction.4 highly hindered alkylphosphonates were synthesized by the modified Michaelis-Becker reaction, using 18-crown ether-6 or quaternary ammonium halides as the phase transfer catalyst.The refraction of many alkylphosphonates were determined and their uarying law was also studied.
