乙缩醛溶液的脱色研究OA北大核心CSTPCD
The decolorization research of acetal solution
以乙缩醛生产过程中精馏塔塔底有色高沸物为研究对象,分别以粒状活性炭、硅藻土、活性白土和粉煤灰为脱色剂,考察了其脱色的可能性,发现活性炭对其脱色最有效.以脱色温度、活性炭用量、脱色时间和搅拌强度为实验因素,以脱色率为考察指标,分别用单因素实验和正交实验对乙缩醛溶液进行了脱色研究,最终确定乙缩醛溶液脱色的最佳条件为:活性炭用量20％,脱色温度20℃,脱色时间6h,脱色率为78.7％.
It toook the high boiling temperature solution in the bottom of the distillation column in acetals production process as research object, respectively by the granular activated carbon, diatomite, activated clay and fly ash for decoloring agents, and investigated their decoloring possibility, Then we found that the activated carbon have a strong influence on the decoloring. In decoloring temperature, the dosage of activated carbon, the bleaching time and stir…查看全部>>
