Abstract Because of high boiling point,high feezing point and heat-sensitivity,the separation and purification process for producing pyrocatechol and hydroquinone is full of difficulty. Aiming at the problems of heat-sensitivity, large amount of outgrowth and production loss due to thermal decomposition and high energy cost during the separation and purification process,this paper dwells on some aspects of heat-sensitive materials. Also this paper put forward directions needing deep research.
