Abstract Heat��sensitive materials are compounds which are prone to heat damage, and the separation and purification of heat��sensitive materials are difficult. Batch distillation is an important method to separate heat��sensitive material. The concepts of “decomposition hazard” and “stability index”, as well as the method to evaluate the distillation equipment for separating heat��sensitive material were introduced. The development of batch distillation processes and equipments for separating heat��sensitive materials were reviewed, such as batch distillation with a recycled cold still pot, batch distillation with dynamic side withdrawal and batch distillation with “wetted dry still pot”.
