ABSTRACT:
The method of making the stable non-pyrophoric solution containing a lithium diorganoamide of the formula, LiNR'R" wherein R' and R" each have from 2 to 6 carbon atoms, in an inert liquid hydrocarbon solvent includes mixing a secondary amine including the R' and R" groups and an alcohol having 3 to 6 carbon atoms with a lithium granulate or powder in the hydrocarbon solvent and reacting the secondary amine, the alcohol and the lithium with addition of an electron acceptor compound, advantageously styrene or isobutene, to form the stable non-pyrophoric solution containing the lithium diorganoamide and a lithium alkoxide having 3 to 6 carbon atoms.
