OXIDATION METHOD OF PRODUCING CARBOXYLIC ACIDS AND ALKENES AND OPTIONALLY ALKENYLCARBOXYLATE OR ALKYLCARBOXYLATE Russian patent published in 2009 - IPC C07C51/215 C07C53/08 C07C69/15 C07C51/25 

FIELD: chemistry.

SUBSTANCE: proposed is a method of oxidising alkane from C₂ to C₄, obtaining the corresponding alkene and carboxylic acid and/or oxidising alkene from C₂ to C₄, obtaining the corresponding carboxylic acid. The method involves addition into the reaction zone of the above mentioned alkane and/or alkene, containing molecular oxygen gas, carbon monoxide and optionally water, in the presence of a catalyst, effective for oxidising the alkane to the corresponding alkene and carboxylic acid and/or effective for oxidising the alkene to the corresponding carboxylic acid at temperature between 100 and 400 °C. Concentration of carbon monoxide is kept between 1 and 20% of the total volume of the initial material added to the oxidation reaction zone. The method can optionally involve further reaction in a second reaction zone.

EFFECT: new oxidation method for producing carboxylic acids and alkenes.
