Abstract
The invention comprises aluminium sulphinates of the general formula Al(SO2R)3 wherein R is an alkyl or aralkyl group having from four to eighteen carbon atoms, and the preparation thereof by reacting an aluminium compound of the general formula AlR3 with dry sulphur dioxide. The reaction is preferably carried out in the presence of an inert solvent or diluent such as an aromatic or saturated aliphatic hydrocarbon, or an ether, generally at a temperature of from 0 DEG to 80 DEG C. or higher. Examples describe the preparation of aluminium tri-octyl sulphinate (from gaseous sulphur dioxide and tri-octylaluminium in hexane), a mixture of aluminium tri-(a - and b -phenethyl) sulphinates (from gaseous sulphur dioxide and triphenethylaluminium), and aluminium and triisobutyl sulphinate (by reacting tri-isobutylaluminium in hexane with liquid sulphur dioxide). Triphenethylaluminium is prepared by reacting styrene with tri-isobutylaluminium at 120 DEG C. in the absence of air. 1,2 - Di - (isobutanesulphonyl) ethane is prepared by heating tri-isobutylaluminium sulphinate with ethylene dibromide and caustic soda in butanol.
