Patent GB-788619-A (GB)
Title: Process for the production of pure aluminium
IPC: C22B21/00
Filed: 1955-08-05
Abstract: Olefines are produced by heating to decomposition an organic Al-compound of the general formula (R.R1.CH-CH2)2.Al.X in which R, R1 represent the same or different saturated aliphatic radicals, and X represents either the group R.R1.CH-CH2- or a hydrogen atom.  For example, Al tri-isobutyl is heated to between 200 DEG  and 300 DEG C. or even higher; or it may first be heated to about 150 DEG  C. to split off isobutylene and produce diisobutyl Al hydride which is further heated at 200-300 DEG  C. to liberate Al, hydrogen and butylene.ALSO:Hydrogen is produced by heating to decomposition an organic A.C. compound of the general formula (R.R1.CH-CH2)2.Al.X in which R, R1 represent the same or different saturated aliphatic radicals, and X represents either the group RR1CH-CH2- or a hydrogen atom.  For example Al triisobutyl is heated to between 200 DEG  and 300 DEG  C. or even higher; or it may first be heated to about 150 DEG  C. to produce diisobutyl Al hydride which is further heated at 200-300 DEG  C. to liberate hydrogen, Al and an olefine.ALSO:Pure Al is produced by heating to decomposition an organic Al compound of the general formula: (R.R1.CH-CH2)2.Al.X, in which R, R1 represent the same or different saturated aliphatic radicals and X represents either the group R.R1.CH-CH2-or a hydrogen atom.  For example Al triisobutyl (C4H9)3Al is heated to between 200 and 300 DEG C. or even higher; or may be heated first to about 150 DEG C. to produce diisobutyl Al hydride which is further heated to 200-300 DEG C. to liberate Al, hydrogen and an olefine.  The metal may be produced as a liquid deposit on molten Al by passing vapour of the compound over the molten Al, or as films on hot (especially metal) surfaces by bringing the latter in contact either with vapour of the compound preferably in vacuo or in a hydrogen atmosphere, or with the liquid compound.  The Al film may be stripped from the surface as a compact sheet.  Crude Al may also be refined by dissolving in a mixture of isobutylene and hydrogen to form Al triisobutyl which after filtering or vacuum distillation is heated to decomposition; the isobutylene and hydrogen also thus produced are re-used to make the process cyclic.  Other olefines e.g. 2-methyl-pentene-(1) may also be used. Specification 770,707 [Group IV(b)] is referred to.
