Abstract: A method of treatment of an aqueous effluent stream obtained during production of furfural is disclosed. The aqueous effluent stream containing organic solvents, furfural, and water is subjected to azeotropic distillation to obtain a distillate stream and a treated effluent stream having lower BOD and COD values which can be further reduced by biomethanation.

Abstract: Processes for the preparation of furfural from a xylose containing feedstock and more particularly to an elevated temperature conversion of a xylose containing feedstock to furfural in acidic conditions are described. The described process uses a mixture of two solvents in which the humins are formed and solubilized. The described process is operated in continuous mode with no significant amounts of solid by-products formation.

Abstract: The present invention provides an improved process for the liquid phase oxidation of toluene to benzaldehyde with high selectivity and good activity in an organic acid medium using a catalyst system consisting of transition metal/metals and bromide as a promoter in the presence of lean oxygen.

Abstract: Process for the synthesis of polyurethane derivatives from aromatic polyamine compounds. The method involves the reaction of an aromatic polyamine compound with CO and O2 in the presence of a catalyst comprising a Group VIII or lanthanide metal on a solid support and a halogenide promoter.

Abstract: The present invention provides an improved process for the production of carboxylic acids by the carbonylation of alcohol. The process involves contacting an alcohol with carbon monoxide in the presence of a nickel compound, a heterocyclic organic compound and an iodide promoter to produce the corresponding carboxylic acid. The improvement relates to the use of heterocyclic organic compound as a promoter containing at least two heteroatoms of which at least one is selected independently from S or N, which provides an inexpensive and stable catalyst system.

Abstract: Methanol is reacted in presence of catalyst system comprising of an iron containing compound and a tin containing compound with or without an organic compound containing C, N, O, P, S, diamine, diketone, and or diphosphines as a ligand to produce acetic acid or methyl acetate. The reaction is effected in a solvent containing nitro or nitrite group.

Abstract: The present invention provides a single step process for the preparation of p-aminophenol by contacting a mixture of nitrobenzene and water with hydrogen over a solid acid catalyst, terminating the reaction to obtain a reaction mixture containing the product, extracting the reaction mixture with an organic solvent, separating the aqueous layer containing the product, and then concentrating the aqueous layer by any conventional method to obtain the product.

Abstract: A process for the hydrogenation of organic compounds using water soluble catalyst in a biphasic media by: (A) forming an organo-water dispersion of (i) an organic phase having (a) an organic compound and (b) an organic solvent, and (ii) an aqueous phase having a water soluble group VIII metal catalyst composition and a water soluble ligand; and (B) contacting said dispersion with hydrogen to provide an interfacial reaction between said organic compound and said hydrogen, giving significant enhancement in the rate of reaction to produce saturated organic compound as compared to a reaction carried out in the absence of said water immiscible ligand.
