ABSTRACT:
Palladium values are separated from the products of reaction resulting from the carbonylation of a conjugated diene with carbon monoxide in the presence of an alcohol, a halogenated hydracid and a palladium catalyst, by (i) contacting the carbonylation reaction medium with a nitrogen, phosphorus or arsenic quaternary onium salt, a polar alcohol and an apolar, aliphatic or cycloaliphatic hydrocarbon solvent, and permitting the resulting admixture to phase separate into an alcohol phase and an organic phase; (ii) decanting/separating said alcohol phase from said organic phase; (iii) recovering the palladium values and the quaternary onium salt from said alcohol phase; and (iv) recovering the products of carbonylation from said organic phase.
