titleOfInvention | Process for the manufacture of halogenated propanes containing end-carbon fluorine |
abstract | A process is disclosed for producing a compound of the formula: CF3CHXCF3-z Y z where X and Y are independently selected from the group consisting of H and Cl, and z is 0 or 1. The process involves (1) contacting CCl3CHXCC3-z Y z,CCl2-z Y z=CXCC3, and/or CCl2CX=CC3-z Y z starting material, with hydrogen fluoride at a temperature of less than 200 .degree.C to produce a fluorination product of said starting material which includes at least 90 mole percent total of C3HXY2Cl6-z-x F x saturated compounds and C3XY z Cl5-z-y F y olefinic compounds, wherein x is an integer from 1 to 6-z and y is an integer from 1 to 5-z, (the fluorination product including no more than about 40 mole percent of the desired product, CF3CHXCF3-z Y z); (2) contacting saturated compounds and olefinic compounds produced in (1) with hydrogen fluoride in the vapor phase at a temperature of from 200 .degree.C to about 400 .degree.C in the presence of a fluorination catalyst; and (3) reacting a sufficient amount of said compounds, wherein x is an integer from 1 to 5-z and olefinic compounds produced in (1) with hydrogen fluoride in the vapor phase at a temperature of from 200 .degree.C to about 400 .degree.C in the presence of a vapor phase fluorination catalyst to provide an overall selectivity to CF3CHXCF3-z Y z of at least about 90 percent based upon the amount of starting material reacted with HF in (1) and (2). |
