ISURF #05189 describes the conversion of waste polyolefins into fatty alcohols or fatty acids by early metal or lanthanide-catalyzed chain cleavage. The alcohols or acids derived by this method are high value and useful as surfactants, detergent agents, or lubricants.
The catalyst supports a pseudo reverse-polymerization reaction, proceeding via a C-H bond activation and B-alkyl elimination for carbon-carbon bond cleavage in a solvent free reaction. This type of reaction, while well-known has never been applied to high molecular weight materials before. Typical high carbon number acids are prohibitively expensive because their synthesis tends to be from the “ground up” and it is hard to achieve larger than C18 molecules in this fashion. Other deconstruction methods that would yield acids, such as pyrolysis tend to require difficult separation. ISURF #05189 yields very few, easily separable molecules of high value with chain lengths C20 or greater. Depending on temperature and specific ligands, different chain-lengths and functionalizations are achievable in high yields.
