催化法制备中间相沥青的研究进展
A review of the catalytic preparation of mesophase pitch
摘要
Abstract
Because of its high purity and excellent orientation,mesophase pitch is a superior precursor for high-performance car-bon materials.However,the preparation of top-notch mesophase pitch faces challenges.Catalytic polycondensation at low temperat-ures is more favorable for synthesizing mesophase pitch,because it circumvents the high-temperature free radical reaction of other thermal polycondensation approaches.The reaction is gentle and can be easily controlled.It has the potential to significantly im-prove the yield of mesophase pitch and easily introduce naphthenic characteristics into the molecules,catalytic polycondensation is therefore a preferred method of synthesizing highly spinnable mesophase pitch.This review provides a synopsis of the selective pre-treatment of the raw materials to prepare different mesophase pitches,and explains the reaction mechanism and associated research advances for different catalytic systems in recent years.Finally,how to manufacture high-quality mesophase pitch by using a cata-lyst-promoter system is summarized and proposed,which may provide a theoretical basis for the future design of high-quality pitch molecules.关键词
