摘要：
One or more triorganophosphite components are separated from a crude phosphite mixture containing acidic hydrolysis products. The crude phosphite mixture is contacted with a basic additive to produce a second mixture comprising a first phase and a second phase. The first phase comprises the basic additive and one or more acidic hydrolysis products and the second phase comprises one or more triorganophosphite components.
