1-Hexene was ethoxylated with ethanol and ethanol-water mixtures mimicking bioethanol in a liquid phase, continuous flow process over a fixed bed of zeolite beta catalyst at a reaction temperature of 423 K and a pressure of 6 MPa. The selectivity for ethoxy alkanes on a hexene basis exceeded 90%. GC-MS, 1H & 13C-NMR and 13C DEPT NMR confirmed the main reaction products to be 2-ethoxy hexane and 3-ethoxy hexane in molar ratio 20:1. Side products were diethyl ether from ethanol and dodecenes and hexanol from 1-hexene. Under optimized reaction conditions, the catalyst was stable for at least 14 hours on-stream. The 2-ethoxylation activity of 1-alkenes by zeolite beta was confirmed in reactions with 1-octene and 1-decene. 1-Alkenes can be synthesized out of biomass via conversion into synthesis gas and the Fischer-Tropsch process. The here presented ethoxylation process could contribute green chemicals to the diesel pool and presents a pathway for synthesis of high boiling solvents.
