摘要
针对2,6-二特丁基对甲酚(BHT)的特点,采用CY金属规整丝网填料改造2,6-二特丁基对甲酚精馏系统筛板塔,技改后产品中BHT的含量≥99.5%(质量分数),产品结晶点≥68.7℃。
Considering the characteristics of 2,6ditertbutylpcresol(BHT),using CY metal structure packing,revamped sieve tray towers in the 2,6ditertbutylpcresol distillation system.After revamping,the concentration 2,6ditertbutylpcresol of product995(mass fraction),the crystallization point687,The designed production was approachable.
