title: Microwave-promoted hydrolysis of plant seed gums on alumina support.
abstract: Using a catalytic amount of potassium persulfate (1.48 x 10(-4)M), eight different seed gums were fully hydrolyzed on alumina support under microwave irradiation. The hydrolysis time varied between 1.33 and 2.33 min depending upon the seed gum structure. The used solid support could be easily separated from the hydrolyzates and recycled. However, under microwave field in an aqueous medium, the same amount of persulfate was unable to hydrolyze the seed gums. Solid-supported microwave hydrolysis has been compared with the microwave-enhanced aqueous hydrolysis (using K2S2O8 or 0.1N H2SO4) and also with the conventional hydrolysis procedures.
