回收醇净化工艺技术在增塑剂酯化工段中的应用

Purification Technology of Recycled Alcohol in the Plasticizer Esterification Section

针对增塑剂生产中回收醇使用时出现的酯化反应"冲料"、延长酯化时间、影响产品质量等现象。研究了回收醇净化工艺技术在增塑剂酯化工段中的应用。该项技术的应用,明显提高了生产产量及生产效率,还降低了原料消耗,产品质量不仅得到提高还能保持稳定。

Through discussion on the ＂back flush＂, extension the reaction time and the impact on product quality which occurred in the process of production of plasticizer, this paper studies the purification technology of recycled alcohol in the plasticizer esterification Section. The application of this technology improves output and production efficiency significantly, but also reduces the consumption of raw materials, product quality be improved and stable.
