摘要：

A significant improvement in a process to produce epichlorohydrin through the use of glycerin as renewable feedstock is presented. The glycerin to epichlorohydrin (GTE) process proceeds in two chemical steps. in the first step, glycerin is hydrochlorinated with hydrogen chloride gas at elevated temperature and pressure to a mixture of 1,3-DCH (1,3-dichlorohydrin, 1,3-dichloropropan-2-ol) and 2,3-DCH (2,3-dichlorohydrin, 2,3-dichloropropan-1-ol), using a carboxylic acid catalyst. In the second step, the mixture of dichlorohydrins is converted to epichlorohydrin with a base. This solventless process represents all economically and environmentally advantageous, atom-efficient process to an existing commodity chemical that can employ a renewable
