摘要
以粗对甲酚作原料通过分步结晶技术得到高纯度对甲酚。在结晶过程中研究了连续通气、脉冲通气和原料纯度对结晶分离度的影响;在发汗过程中,研究了恒温发汗和变温发汗对发汗提纯的影响。
High quality p cresol was obtained from crude feed by means of fractional crystallization The influence of various operational conditions such as the patterns of gas supply and impulse of gas and purity of crude feed on the crystallization separation, the influence of sweating at constant temperature and at varying temperatures on sweating separation were investigated
