本发明提供了一种高纯度、低有机物残留三醋酸甘油酯的生产方法,克服了现有三醋酸甘油酯制备工艺对有机残留物吸附程度低,难以达到国家相关强制性标准要求,导致的产品合格率下降,生产成本上升的问题,包括以原料预处理、酯化反应、深度反应、后续精制等步骤,通过对三醋酸甘油酯半成品的吸附脱色工艺进行改进,选用新的生物吸附剂,最大程度降低其中有害有机物的残留,满足国家强制标准的要求,提高产品合格率。
The invention provides a production method of high-purity and low organic residual triacetin to overcome the problems that the preparation process of the existing triacetin has a low degree of adsorption to the organic residues, it is difficult to meet the requirements of the national compulsory standard, and the qualified products are qualified Rate declining and production cost rising, including the steps of raw material pretreatment, esterification reaction, deep reaction and subsequent purification. Through the improvement of the adsorption decolorization process of the triacetin semi-finished products, the new bio-sorbent is selected to the maximum extent Reduce the residues of harmful organic substances, to meet the national mandatory standards, improve product yield.
