Abstract: 1,195,877. Separation of vaporous aldehydes obtained in the oxo process. BADISCHE ANILIN- & SODA FABRIK A.G. 29 Nov., 1967 [30 Nov., 1966], No. 54282/67. Heading C2C. Vaporous aldehydes are separated from offgas formed in the oxo process, by scrubbing the offgas with an oxonation product boiling above 95 C. and/or a hydrogenated oxonation product boiling above 95 C. Preferably 0À1-2 kg. of the scrubbing material is used per cubic metre of offgas to be scrubbed. Examples recover (a) propionaldehyde by scrubbing the oxo product obtained from ethylene, carbon monoxide and water with a mixture comprising npropanol, para-propionaldehyde and higher boiling condensation products of propionaldehyde, (b) n - butyraldehyde and isobutyraldehyde. Valeraldehyde is also particularly suitable for separation by the method of the invention.

Abstract: Production of beta -ionone by reaction of 3,7-dimethylocten-(7)-yn-(1)-ol-(3) with a lower alkanol ester of acetoacetic acid at a temperature of from 100 DEG to 400 DEG C and treating the reaction mixture with an acid catalyst at a temperature of from 100 DEG to 400 DEG C and cyclizing the 6,10-dimethylundecatrien-(3,5,10)-one-(2) obtained by contacting with concentrated sulfuric acid at temperatures of from -30 to +20 DEG C.
