An Integrated Process for the Synthesis of Solid Hydroxylamine Salt with Ammonia and Hydrogen Peroxide as Raw Materials

Abstract

An integrated process was designed for the synthesis of hydroxylamine salt with ammonia and hydrogen peroxide as raw materials; that is, hydroxylamine is produced from a combination process of cyclohexanone ammoximation and cyclohexanone oxime hydrolysis, whereby cyclohexanone and its corresponding oxime, which is circulated, act as the “reaction carrier”. Solid hydroxylamine salt was obtained through the integrated process, which corresponds to an overall yield of 64.2% with respect to ammonia. Moreover, the “reaction carrier”, as well as the catalyst employed, can be recycled in the process.
