Abstract

Continuous process involves (a) directly contacting the gas mixture (contng. is not >5% dicyanobenzene) with a stream of finely divided water in the upper part of a non-filled column, at a temp. at least 10 degrees C higher than crystallisation temp. of dicyanobenzene, (b) allowing the gas mixture and the water to flow downwards together in the column, the amt. of water being such that the cooling rate down the column is not greater than 100 degrees C/sec., so that the dicyanobenzene forms no smoke, (c) cooling the downwardly flowing gas mixture to below the crystallisation temp. of the dicyanobenzene, (d) contacting the dicyanobenzene crystals with another water stream in the lower part of the column, so that an aqs. suspension of dicyanobenzene crystals is formed, (e) discharging the suspension, and (f) separating the dicyanobenzene crystals from the suspension.
