This example is intended to illustrate a method of separating a liquid product containing chloropropanol.Wherein the liquid product containing chloropropanol is prepared by: propylene, 30% by weight aqueous hydrogen peroxide solution (calculated as H 2 O 2 ),37% by weight of hydrochloric acid (in terms of HCl) and water molar ratio of 1:1:1.1:6 mixed, and added to TS-1 molecular sieve, the weight ratio of propylene to TS-1 molecular sieve is 1:3, at 30 ° C Reaction for 12 h.The composition of the chloropropanol liquid product is such that the content of chloropropanol is 40.2% by weight, and the content of unreacted hydrogen peroxide is 0.8% by weight.The unreacted propylene content was 1.1% by weight, the unreacted hydrochloric acid was 2.9% by weight, and the water content was 53.6% by weight.The content of dichloropropane was 0.8% by weight, and the content of propylene oxide was 0.6% by weight.The first component of the organic extractant is 1-methyl-1-cyclopentene (the solubility in water at 20 ° C is less than 1 g / liter, at 20 ° CThe density is about 780 kg / m3, the boiling point is 76 ° C under normal pressure, the second component is 2-chlorobutane (20 ° C in water)Solubility is about 1 g / liter, density is about 870 kg / m3, boiling point at atmospheric pressure is 69 ° C), the first component and the firstThe two-component molar ratio of 1:0.6 was mixed to obtain an organic extractant.
