Description

General description

Sodium aluminate is used in the synthesis of industrial catalyst mesoporous alumina and various aluminum trihydroxide polymorphs.

Application

Sodium aluminate can be used as a catalyst:

• In the transesterification of glycerol with dimethyl carbonate to synthesize glycerol carbonate.
• In the isomerization of D-glucose into D-fructose.
• To synthesize biodiesel from Jatropha oil via transesterification.
• To convert alcohols into the corresponding unsymmetrical carbonate esters via carboxymethylation by using dimethyl carbonate.
