成果简介:本技术以对苯二甲酸(PTA)或其废料、异辛醇为主要原料,在催化剂存在下,先酯化合成增塑剂DOTP,然后经过中和、水洗、脱醇、过滤等操作,最终获得成品。该技术可采用精对苯二甲酸(PTA),也可采用PTA废料为原料,同时,在相同装置也可柔性生产其他增塑剂系列,如邻苯二甲酸二辛酯邻苯二甲酸二丁酯邻苯二甲酸二
Brief introduction of the results: In this technology, terephthalic acid (PTA) or its waste, isooctanol as the main raw material, in the presence of catalyst, the first esterification of synthetic plasticizer DOTP, and after neutralization, washing, dealcoholization, filtration, etc. Operation, the final product. The technology can be refined terephthalic acid (PTA), PTA scrap can also be used as raw materials, but also in the same device can also be flexible to produce other plasticizer series, such as dioctyl phthalate dibutyl phthalate Ester phthalate two
