Hexanolactam is a kind of important production nylon 6 engineering plastic and nylon 6 fiber.Caprolactam production mainly is to adopt ketone-oxime operational path production, in the traditional oximate and Beckmann rearrangement, pimelinketone, ammonia, hydrogen peroxide is placed same reactor, the one-step synthesis cyclohexanone-oxime.Middle organic carbon concentration to hydrogen peroxide in the reaction needs and will be low to moderate below the 50ppm.
High-purity hydrogen peroxide is the deep processed product of industrial hydrogen peroxide, and electron trade is the main application fields of high-purity hydrogen peroxide, mainly as the remover of clean-out system, etching reagent and the photoresist material of semiconductor crystal sheet.According to relevant department prediction, " 12 " afterwards, the demand growth of China's high purity reagent is rapid, market outlook are very wide.The development of China's high purity reagent is started in 20th century the mid-1970s, though obtained certain breakthrough, integral level and advanced international standard still have big gap.The production of high-purity hydrogen peroxide generally is that the technical grade hydrogen peroxide with anthraquinone production is a raw material, wherein except containing a certain amount of inorganics impurity and mechanical impurity, the organic impurities that also contains 10～500mg/L, these organic impurities comprise anthraquinone compounds and ester, alcohol, phenol, ketone compounds etc., and they derive from processes such as additive in the production and material processing, conveying, storage.
In order to remove these organic impurities in the technical grade hydrogen peroxide product, since the 1950's, people have developed many purifying methods in succession, and summary gets up to have following several: the combination of rectifying, absorption, ion-exchange, extraction, crystallization, membrane sepn and several method etc.
What present industrial application was commonplace is the rectification method and the ion exchange resin method of purification.Rectification method generally is used to concentrate hydrogen peroxide, because the organism boiling point is higher, is removed so be enriched in the liquid that do not gasify, thereby makes hydrogen peroxide be purified.But, because separating, enterprise not exclusively reaches carrying of fog-like liquid, volatile organism can follow hydrogen peroxide steam to enter distillation system, so purity generally can be very not high.Can be used as the purifying method in early stage of other purification techniquess.
The ion exchange resin method of purification not only can be removed organic carbon, and part that can be removed impurity metal ion such as Fe, Al, Sn plasma.The resin regeneration process is simple, and resin reuses repeatedly.But in the practical application, ion exchange resin needs to consume a large amount of energy consumptions when regeneration, and because the class gummy solid occurs, causes resin that problems such as obstruction take place.
Membrane sepn makes that by absorption and effects such as kapillary circulation, screening hydrogen peroxide solution obtains purifying.
