  • Oxidation catalyst, the process for the preparation thereof and green process for selective aerobic oxidation
    Patent number: 9302255
    Abstract: Described herein is a novel, cost effective, stable and recyclable catalyst composition i.e. A-B-OMS, wherein ‘A’ is selected from noble and transition metals; ‘B’ is selected from alkali or alkaline earth metals; and OMS is octahedral molecular sieve which includes synthetic todorokite (OMS-1) and cryptomelane (OMS-2); and characterization thereof. Further the invention provides base free green process for selective aerobic oxidation of 5-hydroxymethylfurfural (HMF) catalyzed by said catalyst composition under optimized reaction conditions to obtain high yield of 2,5-furandicarboxylic acid (FDCA) in a shorter span of time. Invention also provides for selective oxidation of glucose to Gluconic Acid, furfural to furoic Acid and glycerol to Glyceric acid. Invention can also applicable for the selective oxidation of hexoses, pentoses, disaccharides to corresponding acids.

  • NOVEL OXIDATION CATALYST, THE PROCESS FOR THE PREPARATION THEREOF AND GREEN PROCESS FOR SELECTIVE AEROBIC OXIDATION
    Publication number: 20150336090
    Abstract: Described herein is a novel, cost effective, stable and recyclable catalyst composition i.e. A-B-OMS, wherein ‘A’ is selected from noble and transition metals; ‘B’ is selected from alkali or alkaline earth metals; and OMS is octahedral molecular sieve which includes synthetic todorokite (OMS-1) and cryptomelane (OMS-2); and characterization thereof. Further the invention provides base free green process for selective aerobic oxidation of 5-hydroxymethylfurfural (HMF) catalysed by said catalyst composition under optimized reaction conditions to obtain high yield of 2,5-furandicarboxylic acid (FDCA) in a shorter span of time. Invention also provides for selective oxidation of glucose to Gluconic Acid, furfural to furoic Acid and glycerol to Glyceric acid.
