Abstract
A number of processes for the formation of insoluble metal alkoxides are disclosed. In one embodiment, there is disclosed a two step process wherein a halide of an at least divalent metal is reacted with an appropriate alcohol in the first step. In the second step, the intermediate compound formed is then reacted with more alcohol, said alcohol forming part of a solvent system in which the final metal alkoxide formed is insoluble. In another embodiment, a two step process is disclosed wherein the intermediate formed in the first step is isolated, and then in the second step the intermediate is reacted with an appropriate alcohol to yield the final product. The final embodiment of the present invention comprises a one step process for the production of insoluble metal alkoxides wherein a halide of an at least divalent metal is reacted with an appropriate alcohol in the presence of an excess amount of a hydrogen halide acceptor in a solvent in which the hydrogen halide compound formed is soluble.
