CONTINUOUS PROCESS TO MAKE AMINE OXIDE

摘要

A continuous process for making amine oxide surfactant comprising the steps of (a) providing the following components; a tertiary amine composition and an aqueous hydrogen peroxide composition, (b) mixing the components from step a) in a mixing device, (c) passing the mixture exiting the mixing device from step b) into an aqueous amine oxide composition comprising from 65 to 80 wt % amine oxide, (d) adjusting the temperature of the amine oxide composition made in step c) to between 40 and 80° C., (e) collecting the amine oxide surfactant; and wherein, for every 1 part of the component mixture from step b) being passed into the aqueous stream in step c), between 8 and 30 parts of the temperature adjusted amine oxide composition from step d) are recycled back to step b) and passed through the mixing device together with the components from step a).
