Stabilization process of hydroxy-ketonic products subject to instability and color evolution problems

机译:羟基酮产品的稳定化过程存在不稳定和颜色演变的问题

摘要

A method of stabilizing hydroxy ketone products is provided in which a product such as a diacetone alcohol which has high instability and colour evolution, making transport difficult, is stabilized by adding para-tertiary-butyl-catechol in solid form or in solution. A colour stability of at least 100 days can be achieved.
