摘　　要：介绍了一种由邻氨基苯甲醚经重氮、水解过程生产愈创木酚过程中产生的水汽蒸馏废水的综合利用方法。将愈创木酚水汽蒸馏所得水相直接应用于香兰素的合成,大大减少了香兰素缩合反应所需的投料工艺水,同时省略了愈创木酚水汽蒸馏水相的萃取与废水处理过程,达到节能与循环利用的目的。按公司的生产规模,年可减少约20万t废水,使香兰素绿色生产工艺上了一个新台阶。The comprehensive utilization of wastewater generated from the steam distillation of guaiacol which was produced through the diazo and hydrolysis processes from o-aminoanisole is described in this paper. The water phase generated from the steam distillation of guaiacol is directly applied to the synthesis of vanillin, so that the amount of process water required for adding to the condensation reaction of vanillin is decreased significantly, and the steps for extraction of aqueous phase in steam distillation of guaiacol and the treatment process of wastewater are also omitted. According to the scale of production of our company, the amount of wastewater can be reduced by about 200 thousand tons annually, the comprehensive utilization of guai acol wastewater leads the green production process of vanillin to a new level.
