A composite solid base catalyst, a manufacturing method thereof and a manufacturing method of glycidol are provided. The composite solid base catalyst includes an aluminum carrier and a plurality of calcium particles. The plurality of calcium particles are supported by the aluminum carrier. Beta basic sites of the composite solid base catalyst are 0.58 mmol/g-3.89 mmol/g.

Composite solid base catalyst, manufacturing method thereof and manufacturing method of glycidol

Provided is a process of preparing dichloropropanol, DCP. The process includes the step of: subjecting a three-carbon material to a first chlorination reaction with an aqueous hydrochloric acid solution in the presence of a carboxylic acid catalyst; adding the three-carbon material into the first mixture solution to undergo a second chlorination reaction and obtain a second mixture solution containing less than 13 wt % of hydrochloric acid; distilling the second mixture solution; and purifying the overhead product by oil-water separation to obtain DCP from the oil phase. By lowering the concentration of the hydrochloric acid contained in the mixture to be distilled, the DCP product can be straightly obtained via distillation and oil-water separation, thereby effectively simplifying the process of preparing DCP.
