Abstract
A mixture of b -, g -, and d -AlF3 is prepared by treating AlCl3 with HF and heating the amorphous AlF3 formed at 350-400 DEG C., or by passing anhydrous HF over Al2O3 at 200-500 DEG C. until 0.3-6 moles HF per mole of Al2O3 have reacted. d -AlF3 belongs to space group Oh9-I mcm., has a unit cell parameter a=14-34 <\>rA, a unit cell volume of 29,500 <\>rA, contains 64 mols AlF3 per unit cell, and has a calculated density of 3.025 g./c.c. g -AlF3 is prepared by heating b -AlF3.3H2O at 150-450 DEG C. until water ceases to be evolved. g -AlF3 belongs to the space group D63d-R3c, has unit cell parameters a=5.0 <\>rA and c=12-28 <\>rA and a unit cell volume of 3459 <\>rA3, contains 6 mols per unit cell and has a calculated density of 3.130 gm./c.c. X-ray characteristics of g - and d -AlF3 are given.ALSO:Vinyl fluoride and 1,1-difluorethane are prepared by passing a mixture of hydrogen fluoride and acetylene at 250-400 DEG C. and 0.1-4 atmospheres over beta- or gammaaluminium fluoride catalyst, or a mixture thereof with delta-aluminium fluoride, the molar ratio of hydrogen fluoride to acetylene being from 1-5, and the feed rate of acetylene being from 10-4000 ml./gm. of catalyst/hour. The products may be separated by distillation. Examples are given including comparisons with the use of alpha-aluminium fluoride and of alumina. The preparations of the various forms of aluminium fluoride are described (see Division C1).ALSO:A mixture of beta-, gamma-, and delta aluminium fluorides is an effective catalyst for the reaction of acetylene and hydrogen fluoride, to form vinyl fluoride and 1, 1-diffluoroethane. The catalytic mixture may be prepared by treating aluminium chloride with hydrogen fluoride and heating the amorphous aluminium fluoride formed at 350-400 DEG C., or by passing anhydrous hydrogen fluoride over alumina at 200-500 DEG C until 0.3-6 moles hydrogen fluoride per mole of alumina have reacted.
