PROCESS OF PRODUCING CARBOXYLIC ACIDS, ALCOHOLS, OR ESTERS (OPTIONS) Russian patent published in 2006 - IPC C07C51/14 C07C53/126 B01J31/22 

FIELD: industrial organic synthesis.

SUBSTANCE: subject of invention is continuous carbonylation of long-chain aliphatic hydrocarbons to produce alcohols, acids, and other oxygen-containing products such as esters. Process comprises paraffin dehydrogenation, carbonylation, and fraction distillation-mediated end product recovery. Advantageously, mixture of paraffins containing different number of carbon atoms isolated from kerosene fraction is processed. Non-converted paraffins are recycled into dehydrogenation zone. Prior to be fed into carbonylation zone, stream is processed by selectively hydrogenating diolefins. In the carbonylation stage, homogenous catalytic system is used containing palladium/imidazole or palladium/triphenylphosphine complex, aliphatic acid (preferably formic acid), and solvent. Catalytic system further includes promoter selected from group: lithium iodide, zirconium chloride, tin chloride, and lithium bromide.

EFFECT: simplified technology, increased conversion of raw materials and selectivity in formation of desired products.
