摘要

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. ...
