Abstract
The present invention relates to a cresol preparation method, wherein DTE, a byproduct produced by the cresol preparation method, is separated and recycled to a reaction step, thereby inhibiting the production of DTE. The cresol preparation method according to the present invention is a process in which a cresol is prepared by a reaction of halo-toluene and a basic aqueous solution, and the method comprises a step of separating DTE, a byproduct of the process, and re-feeding DTE to the reaction step of halo-toluene and the basic aqueous solution.
Claims8
A method of preparing cresol by a process of reacting halotoluene and a basic aqueous solution, the method comprising:
- separating DTE which is a by-product of the process and refeeding the DTE into the reaction process of halotoluene and a basic aqueous solution.
