Title:
【発明の名称】ポリスクシンイミドの脱色
Document Type and Number:
Japanese Patent JPH10512903
Kind Code:
A
Abstract:
There is disclosed a process for decolorizing polysuccinimide by means of contacting the polysuccinimide in the solid state with an aqueous solution of a bleach. Typically, polysuccinimide is placed into a solution of hydrogen peroxide to form a slurry with solid particles whereby the color of the polysuccinimide is greatly reduced. Separation of the bleach solution is performed easily by means of solid liquid separation such as by filtration rendering the polysuccinimide acceptable for use directly into detergent formulations.
