There is described an essentially two step process for the preparation of benzylalcohols including those benzylalcohols having substituents on the benzyene ring by reaction of a substituted or unsubstituted benzyl halide with a formate typically an alkali or alkaline earth metal formate to form the corresponding substituted or unsubstituted benzyl formate. In the second step of the process the benzyl formate is contacted with an alcohol whereby the same is converted into the desired benzylalcohol. Both steps can be performed employing catalysts. Described in the specification is the realization of the desired product in exceptionally high yields in a short period of time whereby the process is characterized by high space-time yields.
描述了一种基本上分为两个步骤的过程,用于制备苄醇,包括那些苄醇在苯环上有取代基的情况,通过将取代或未取代的苄卤与一种甲酸酯(通常是碱金属或碱土金属甲酸酯)反应,形成相应的取代或未取代的苄甲酸酯。在该过程的第二步中,苄甲酸酯与醇接触,从而转化为所需的苄醇。这两个步骤都可以使用催化剂进行。在说明书中描述了在短时间内以极高产率实现所需产品的情况,该过程以高空时产率为特征。
