Title: Improvements in or relating to the preparation of metal slurries and also metal alkyls
Inventor: KING RALPH WILLIAM
IPC: C07F3/00
Filed: 1956-08-14
Abstract: Metal alkyls are made from atomized metal (preferably a metal from Groups II or III of the Periodic Table) either after the metal is atomized and forms a slurry in a hydrocarbon (see Group II) or, if the slurry is to be used directly for the preparation of metal alkyls, an olefine is used as a gaseous atomizing medium, preferably a butylene (especially isobutylene) but others such as pentenes, hexenes and heptenes may be employed.  A metal in olefine slurry and some preformed metal alkyl are mixed together and hydrogen passed in, preferably a two-stage process being used. In this some metal alkyl hydride is formed in the first stage and the reaction proceeds to completion in the second stage.  The preparation of aluminium triisobutyl is disclosed.ALSO:Metal particles (particularly of a metal from Groups II or III of the Periodic Table) are obtained as a slurry by atomizing the molten metal in a vapour stream of a non-reacting and non-decomposing hydrocarbon and condensing the vapour.  A reactive slurry can be used to form metal alklys (see Group IV(b)).  The metal e.g. aluminium, is fed in wire form from a nozzle into an alternating magnetic field for induction melting, the nozzle also carrying the compressed, vaporized hydrocarbon. The hydrocarbons preferably possess an molecular weight not exceeding 100.
