METHOD FOR THE FRACTIONAL CONDENSATION OF A HOT GAS MIXTURE CONTAINING ACRYLIC ACID OR METHACRYLIC ACID AND HAVING A HIGH PROPORTION OF NON-CONDENSABLE CONSTITUENTS

摘要

A PROCESS FOR FRACTIONAL CONDENSATION OF A HOT GAS MIXTURE CONTAINING ACRYLIC ACID OR METHACRYLIC ACID AS A CONDENSABLE COMPONENT AND AT LEAST A SECOND CONDENSABLE COMPONENT AND FUTHERMORE A HIGH PROPORTION OF AT LEAST ONE UNCONDENSABLE COMPONENT, WHICH COMPRISES PASSING THE GAS MIXTURE THROUGH A COLUMN HAVING SEPARATORY INTERNALS AND CONDENSING OUT THE CONDENSABLE COMPONENTS BY COOLING.
