Abstract: Gas coolers in which hot gasses are brought into contact with a moving cooling liquid film are used for cooling hot gasses and thus for preventing the formation of condensation cores. In a process for cooling hot gaseous reaction products from gas phase reactions for preparing glyoxal of compounds of general formula (I): H2C=C(R )-C(R )=O, in which R is hydrogen or methyl and R is hydrogen or OH, in particular acrolein, methacrolein, acrylic acid and methacrylic acid, hot gaseous reaction products are brought into contact with a cooling liquid in a gas cooler, and the cooling liquid is present in the form of a moving liquid film.

Abstract: A process for the rectification and sepn. of unsatd. carboxylic acids (I) from the solvents in which (I) are absorbed after the synthesis reaction. The process involves interrupting the rectification and flushing out the rectification column with basic soln.

Abstract: IN A PROCESS FOR THE SEPARATION BY RECTIFICATION OF UNSATURATED CARBOXYLIC ACIDS FROM SOLVENTS IN WHICH THE ACIDS WERE ABSORBED AFTER THE SYNTHESIS REACTION, THE RECTIFICATION IS BRIEFLY INTERRUPTED AND THE RECTIFICATION COLUMN IS FLUSHED WITH A BASIC SOLUTION. THE INTERRUPTION IS CARRIED OUT AT REGULAR TIME INTERVALS. THE BASIC SOLUTION USED IS AN AQUEOUS SOLUTION OF ALKALI METAL AND/OR ALKALINE EARTH METAL HYDROXIDE, PREFERABLY NAOH, KOH, CA(OH)2 OR THEIR ANHYDROUS OXIDES; A1KA1INE POLAR ORGANIC SOLVENTS AS AMINES OR AMIDES CAN BE USED, TOO.

Abstract: Phosphorus-free inhibitor compositions containing (a) N-oxyl radical(s) and (b) a phenol, optionally substituted with up to three 1-4C alkyl, 2-4C alkenyl or 7-10C aralkyl groups. Phosphorus-free inhibitor compositions (I) containing (a) N-oxyl radical(s) and (b) a compound of formula (X). n = 0-3; R = 1-4C alkyl, 2-4C alkenyl or 7-10C aralkyl. Independent claims are also included for: (i) a method for stabilizing materials containing ethylenic double bond(s) against unwanted polymerisation by adding (I) to the material; (ii) a mixture containing an ethylenically unsaturated compound and an effective amount of (I) as polymerisation inhibitor.
