The invention provides a method for separating one or more triorganophosphite components from a crude phosphite mixture containing acidic hydrolysis products, the method comprising:
contacting said crude phosphite mixture with a basic additive to produce a second mixture comprising a first phase and a second phase, wherein said first phase comprises the basic additive and one or more components independently selected from the group consisting of (R
