A method for preparing different Xin thiol (by machine translation)

The present invention relates to the field of fine chemicals, in particular relates to a process for preparing thiols different Xin, it adopts isooctanol, hexabromo, DMAP catalyst, thiourea, polyesters sodium solution, such as sulfuric acid the original supplementary material to brominated, condensation, hydrolysis reaction, after the reaction, then drying and rectification to get different Xin thiol finished product. The preparation method is simple, few steps, yield as high as 94.16%, and in the bromination reaction not introduced in phosphorus and bromine from participating in the reaction reduces the security risk coefficient.
