Abstract

The invention relates to the field of chemical engineering, in particular to a refining method of methyltris (methylethylketoxime) silane. Modified activated carbon is used for adsorbing and refining a methyltris (methylethylketoxime) silane crude product, then a cation modified polyethersulfone filter membrane is used for finely filtering the product, the surface of the cation modified polyethersulfone filter membrane contains quaternary ammonium bond groups, and the cation modified polyethersulfone filter membrane has a good adsorption effect on hydroxyl compounds; a hydrolysis product methyltrihydroxysilane of the product can be adsorbed and removed to obtain a high-purity product; and the refined methyltris (methylethylketoxime) silane product obtained by the method disclosed by the invention is high in purity and light in chroma, and the market competitiveness of the product is greatly enhanced.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a method for refining methyl tributylketoxime silane. Background technique [0002] The market demand for methyl tributyl ketoxime silane is growing rapidly. Compared with other sealants, neutral silicone sealants are almost non-corrosive, have low toxicity and low activity, which makes the curing time of room temperature vulcanized one-component silicone rubber shorter short and so on. At present, the most widely used cross-linking agent at home and abroad is dealcoholized room temperature vulcanized single-component silicone rubber, accounting for more than 95% of the total. Therefore, there is a good market for purified high-quality methyl tributyl ketone aliphatic silane Application prospect. [0003] CN204428891U discloses a kind of extraction tower that is used for methyl tributyl ketoxime base silane, comprises tower body, baffle plate, vertical stirring device, horizont...
