摘要
Abstract
Using acetone oxime and hydrochloric acid as raw materials,the hydrolysis of acetone oxime was carried out to prepare hydroxylamine hydrochloride. A quantitative analysis method by combining HPLC detection and redox titration was set up for the analysis of the reversible hydrolysis reaction equilibrium. The obtained analysis data of the combined method had a recovery of 99.64%and a RSD of no more than 2.04% (n=6). After that,a reactive distillation device was set up for the hydrolysis of acetone oxime,and the process technology of the reactive distillation was studied and optimized. The result showed that,at condition when the molar ratio of acetone oxime to HCl=1∶2, HCl mass fraction at 38%,heating temperature at 130℃ and reaction time at 3h,the raw material conversion of acetone oxime approached around 89% and the product yield of hydroxylamine hydrochloride reached about 84%.关键词
