Hydrolytically stable phosphite compositions

Abstract

Processes for alkylating hydroxyaryl compounds by reacting a hydroxyaryl with at least one olefin from a complex hydrocarbon stream. The complex hydrocarbon stream preferably comprises a fraction of a cracked hydrocarbon feed stream or reaction products of a dehydrogenation of a paraffinic raw material. The olefin in the complex hydrocarbon stream is preferably a branched olefin, for example isobutylene or isoamylene. The alkylated compositions are suitable for forming liquid phosphite compositions.
