| titleOfInvention | Process for producing halogenated propane containing fluorine substituted in terminal carbon |
| abstract | The process of the invention discloses a process for the preparation of compounds of formula CF 3 CHXCF 3-z Y z , wherein X and Y are independently selected from the group consisting of H and Cl, z is 0 or 1. The process of the invention comprises (1) a compound of formula CCl 3 CHXCCl 3-z Y z , a compound of formula CCl 2-z Y z = CXCCl 3 , a compound of formula CCl 2 = CXCCl 3-z Y z , wherein X And Y is independently selected from the group consisting of H and Cl, z is 0 or 1) and a starting material selected from the group consisting of mixtures thereof in contact with hydrogen fluoride at a temperature of less than 200 ° C. (It is a saturated compound of the formula C 3 HXY z Cl 6-zx F x and an olefin compound of the formula C 3 XY Z Cl 5-Zy F y , wherein x is an integer of 1 to 6-z, and y is 1 To at least 90 mole% of a compound selected from the group consisting of 1 to 5-z, and up to about 40 mole% of CF 3 CHXCF 3-z Y z ;n n n (2) vapor-contacting hydrogen fluoride with a compound selected from the group consisting of the saturated compound prepared in step (1) and the olefinic compound at a temperature of 200 ° C. to about 400 ° C. in the presence of a fluorination catalyst; Andn n n (3) a sufficient amount of the saturated compound prepared in step (1) (where x is an integer of 1 to 5-z) and the olefinic compound at a temperature of 200 ° C. to about 400 ° C. in the presence of a vapor phase fluorination catalyst Vapor phase reacting with hydrogen to provide a total selectivity to at least about 90% of CF 3 CHXCF 3-z Y z based on the amount of starting material reacted with HF in steps (1) and (2). |
