New technology for synthesizing 1,3-propylene glycol from glycerin through dehydroxylation method

The invention discloses a new technology for synthesizing 1,3-propylene glycol from glycerin through a dehydroxylation method. The technology comprises the following steps: protecting two hydroxyl groups at the head end and the tail end of a glycerin molecule through using a group protection process, converting a hydroxyl group in the middle of the molecule into a group easy to eliminate, that is a sulfonyloxy group, removing hydroxyl group protection groups, and reducing the sulfonyloxy in the presence of a catalyst in order to obtain the 1,3-propylene glycol product. The technology has the characteristics of few byproducts, easiness in separation, and low cost, is a route with environmentally-friendly and economic dual values, and has wide development prospect.
