At present, the most important method for industrial production of phenol is the so-called cumene process. However, this process has some fundamental and inevitable disadvantages: acetone as byproduct produced in a 1:1 stoichiometry, which in terms of market demand is much smaller than phenol. 目前工业生产苯酚最主要的方法为异丙苯法,该法最大的缺点在于生产苯酚的同时副产等摩尔市场需求量相对较小的丙酮,因而苯酚的生产受到丙酮市场价格的制约。
