摘要:
The invention relates to the synthesis of bisphenols from monophenols and carbonyl compounds such as aldehydes and ketones with concentrated mineral acids such as hydrochloric acid and/or hydrogen chloride gas as acid catalysts and a mercaptan as cocatalyst, which is fixed by an ion-pair bond to a matrix insoluble in the reaction medium.
