摘要： 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 2 O)(R 3 O)POH, (R 1 O)(HO)PO(H) and H 3 PO 3 , wherein R 1 , R 2 R 3 are independently selected from the group consisting of C 1 to C 18 alkyl, C 6 to C 18 aryl and hydroxyaryl, and C 3 to C 18 cycloalkyl and hydroxyalkyl radicals, and wherein R 2 and R 3 can optionally be connected to each other directly by a chemical bond or through an intermediate divalent group R 9 ; and said second phase comprises one or more triorganophosphite components independently selected from the group consisting of (R 4 O)(R 5 O)P(OR 6 ) and ((R 7 O)(R 8 O)PO) n A, wherein R 4 , R 5 , R 6 , R 7 and R 8 are independently selected from the group consisting of C 1 to C 18 alkyl, C 6 to C 18 aryl and C 3 to C 18 cycloalkyl radicals, wherein each of R 4 , R 5 and R 6 can optionally be connected to one or both of the other two directly by a chemical bond or through an intermediate divalent group R 10 , wherein R 7 and R 8 can optionally be connected to each other directly by a chemical bond or through an intermediate divalent group R 11 , wherein A is an optionally substituted or unsubstituted aliphatic, aromatic or heteroaromatic radical, and wherein n is an integer greater than 1; and R 9 , R 10 , and R 11 are independently selected from the group consisting of -O-, -S-, and -CH(R 12 )-, wherein R 12 is selected from the group consisting of H, C 6 to C 18 aryl, and C 1 to C 18 alkyl.
