摘要
分子蒸馏技术是一种适合分离纯化热敏性混合物料的新型分离技术,采用分子蒸馏技术对防冰剂基础组分进行了分离纯化,最佳工艺条件:蒸馏温度120℃、刮膜转速300r/min,冷凝器温度<30℃、蒸馏塔真空压力10^-1~10^-4Pa。并与传统精馏条件得到的产品进行了数据对比,结果表明分子蒸馏工艺得到的产品纯度高达99.5%以上,性能指标满足了规范要求。
Molecular distillation is a new separation technology for separation and purification of heat sensitive mixture material.At the optimum technological conditions obtained: the distillation temperature was 120 centigrade, the speed of the scraper was 300r/min,the temperature of condenser was below 30 centigrade,the vacuum degree was from one tenth to one millionth Pa, the cing-inhibitor basic component was separated,and the purity exceed 99.5 percent,and the performance satisfy standard requirement.
