摘　　要：对T-501在乙醇溶液中的结晶规律进行研究,分析了物料配比、晶种的加入、乙醇浓度对T-501结晶温度点和晶体粒度分布的影响。结果表明随着物料配比的减小,结晶温度点和结晶晶体的粒度呈现明显的下降趋势;晶种的加入可以明显改善产品的粒度发布;而且随着乙醇浓度的升高,结晶温度点和晶体的粒度呈下降趋势。Crystallization Process of Antioxidant T-501 was studied in this work. The effects of feed ratio, addition of seeding and concentration of ethanol on crystallization temperature and crystal size distribution were experimentally investigated. It is shown that the crystallization temperature and crystal size distribution increase with reduce of the feed ratio. Addition of seeding can evidently ameliorate crystal size distribution. The crystallization temperature and crystal size distribution decrease with the increase of concentration of ethanol.
