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.

Convert dichloroisopropyl ether into a halogenated derivative by contacting the dichloroisopropyl ether with a source of hydrogen and a select heterogeneous hydrogenation catalyst under process conditions selected from a combination of a temperature within a range of from 50 degrees centigrade ( C.) to 350 C., a pressure within a range of from atmospheric pressure (0.1 megapascals) to 1000 pounds per square inch (6.9 MPa), a liquid feed volume flow to catalyst mass ratio between 0.5 and 10 L/Kg*h and a volume hydrogen/volume liquid ratio between 100 and 5000 ml gas/ml liquid. The halogenated derivative is at least one of 1-chloro-2-propanol and 1,2-dichloropropane 1, and glycerin monochlorohydrin.
