Abstract
Preparing isopropyl chloride (2-chloropropane) employing propylene, hydrochloric acid and ferric chloride catalyst in an isopropyl chloride solution at effective temperatures and pressure to produce 2-chloropropane. The amount of ferric chloride catalyst is less than that conventionally employed and the temperature and pressure are greater than conventionally employed.
Claims12
A method for the production of isopropyl chloride comprising reacting effective amounts of hydrochloric acid and propylene in a isopropyl chloride solvent containing ferric chloride at a temperature of greater than 50° C. and a pressure greater than 30 psig.
A method for the production of isopropyl chloride by liquid-phase hydrochlorination comprising reacting effective amounts of propylene and hydrochloric acid in the presence of 10 to 350 ppm ferric chloride catalyst in a reactor solution at an operating temperature of 50-80° C. and at a pressure greater than 30 psig.
A method for the production of isopropyl chloride comprising reacting HCl and propylene in the presence of 15-300 ppm of ferric chloride in an isopropyl chloride solvent at a temperature in the range of 50° C. to 80° C. and at a pressure of 30 to 100 psig or higher.
