【摘要】 以月桂酸作原料,经过酰氯化,傅克酰基化,还原等反应合成了直链十二烷基苯,并通过预处理,减压蒸馏,重结晶等方法分离并提纯,产物经¹H NMR进行了表征。优化条件为:在n（月桂酸）:n（氯化亚砜）=1: 2条件下制得月桂酰氯;在n（月桂酰氯）:n（AlCl₃）:n（苯）=1:1.2:8.4,80℃反应9 h条件下制得十二酰基苯,再经黄鸣龙还原得到最终产物直链十二烷基苯,产率可达59.2%。更多还原

【Abstract】 n-Dodecylbenzene was prepared by lauroyl chloridation,Friedel-Crafts acylation and Huang Minglong deoxidization,followed by purification with vacuum distillation and recrystallizaton procedures. The optimum reaction conditions were:lauroyl chloride was first prepared with n(dodecanoic acid):n(thionyl chloride) of 1:2;then lauroyl chloride,aluminum chloride and benzene[in the ratios of n(lauroyl chloride):n(aluminium chloride):n(benzene)=1:2:8.4]reacted at 80℃for 9 h;and finally Huang Minglon deoxidization of laurophenone prepared was carried out with hydrazine hydrate.After vacuum distillation and recrystallizaton,the yield of the final product was 59.2%.The final product linear dodecylbenzene was confirmed by ~1H NMR characterization.更多还原
