Method for synthesizing trimethylhydroquinone through pseudocumene

The invention relates to a method for synthesizing trimethylhydroquinone through pseudocumene. The method for synthesizing the trimethylhydroquinone through the pseudocumene comprises the following steps that the pseudocumene is used as the raw material, a brominating reaction, an oxidizing reaction and a reduction reaction are conducted, and finally the trimethylhydroquinone is prepared. Please see the reaction formula in the specifications. According to the method for synthesizing the trimethylhydroquinone through the pseudocumene, the low-cost pseudocumene is used as the starting raw material, the process route is short, the yield is high, complete cyclic utilization of the bromine element can be achieved through recycling, the method for synthesizing the trimethylhydroquinone through the pseudocumene is a clean synthesizing technology, and the problems that in the prior art, m-cresol is in short supply, and serious pollution is caused in the p-xylene technology are solved.

Bromination of aromatic compounds using ammonium bromide and oxone

A simple, efficient and mild method for the selective bromination of activated aromatic compounds using ammonium bromide as the source of bromine and Oxone as the oxidant in methanol or water as solvent is reported. The reaction proceeds at ambient temperature in yields ranging from moderate to excellent without a catalyst. Georg Thieme Verlag Stuttgart.
