252 67, 570155, 570156, 510177, 510408
Abstract:
A process is disclosed for the manufacture of CFCF═CHand CFCH═CHF. The process involves dehydrofluorinating CFCHFCHF in the presence of a dehydrofluorination catalyst to produce a product mixture comprising CFCF═CHand CFCH═CHF, and recovering said CFCF═CHand CFCH═CHF from the product mixture. The present invention also provides a composition comprising (a) the Z-isomer of CFCH═CHF and (b) HF; wherein the HF is present in an effective amount to form an azeotropic combination with the Z—CFCH═CHF.

Abstract:
1,1,3,3,3-Pentafluoropropene (CFCH═CF, HFC-1225zc) can be produced by pyrolyzing 1,1,1,3,3,3-hexafluoropropane (CFCHCF, HFC-236fa) in the absence of dehydrofluorination catalyst at temperatures of from about 700 C. to about 1000 C. and total pressures of about atmosphere pressure in an empty, tubular reactor, the interior surfaces of which comprise materials of construction resistant to hydrogen fluoride.

It's been a fun ride for Beaver Nation. It appears Oregon State has its best men's basketball coach since Ralph Miller. The Beavers have competed and found a way to win more often than they probably have a right to. That's a credit to Tinkle and his staff.
