MANUFACTURE OF CARBOXYLIC ACID AND ESTER

Title:

MANUFACTURE OF CARBOXYLIC ACID AND ESTER

Document Type and Number:

Japanese Patent JPS588036

Kind Code:

A

Abstract:

An acyl fluoride, e.g., isobutyryl fluoride, is formed by reacting carbon monoxide, an organic compound (e.g., propylene) and anhydrous hydrogen fluoride, in a liquid mixture while feeding the carbon monoxide and organic compound (e.g., propylene) into the liquid mixture's vapor phase which is maintained above the supercritical temperature of the vapor mixture at substantially the same rate as the carbon monoxide, organic compound (propylene) and anhydrous acid (hydrogen fluoride) react. The temperature is 40 to 90 DEG C and the pressure 109-340 bars. The final mole ratio of anhydrous hydrogen fluoride to organic compound in the reacting mixture is 1 to 100 moles of anhydrous hydrogen fluoride to 1 mole of organic compound and the mole ratio of carbon monoxide to organic compound is from 1 to 25 moles of carbon monoxide to 1 mole of organic compound.
