    摘要: There are disclosed improved methods for preparing metal alkoxides from metals and alcohols. The methods involve dry-grinding the metal in an inert atmosphere prior to the addition of the alcohol. When an activator is used, it is usually ballmilled with the metal. Higher yields are obtained, particularly when the metal and alcohol are not very reactive absent an activator. Typical metals are those from Groups 2A, 2B, 3A, and 3B, particularly aluminum, magnesium, and yttrium. Typical alcohols are those which contain up to 16 carbon atoms, particularly those containing 4 or more carbon atoms.

    摘要: Aluminum alkoxides are prepared by the reaction of impure aluminum and monohydric alcohols in a process wherein impure metallic aluminum particles are continuously fed at a metered rate into a stoichiometric excess of alcohol. The novel apparatus disclosed permits the continuous introduction of the aluminum particles into the reactor and removal of non-reactive impurities through columns of ambient temperature alcohol which avoids contact of atmospheric oxygen with the reaction products.

    摘要: A method is disclosed for forming stannic tetra-(tertiary-alkoxides) wherein the alkoxide groups contain from 4 to 8 carbon atoms, which process includes starting with a tin tetrahalide and involves reactions with an alkylamine and a tertiary alcohol. The resulting products are volatile tin compounds and find utility as a source of tin oxide. For example, the compounds may be hydrolyzed with water and then pyrolyzed to provide a source of ultra high purity tin oxide.
