Abstract: The use of ether nitriles (I) as odourants is claimed. (I) are of formula: R-(CH2)m-A-(CH2)n-O-(CH2)2-CN (where R = H, (CH3)2CH- or CH3C(=CH2)-; A = a C-C bond or -C(CH3)=CH-; m = 1-8 and n = 1-5 with the proviso that the total no. of C in (I) = 7-15). (I) may be prepd. (see DT 2121325 and DT 2217494) by reacting corresp. alcohols with acrylonitrile. (I) have a floral-aromatic-fruity odour.

Abstract: In continuous prodn. of poly(alkoxypropylamines) of formula (H2N-CH2CH2CH2O)nR (where n is an integer 2 to 6, and R is residue of a 2-6-hydric alcohol), using a Co-catalyst e.g. Co-oxide on a silica gel carrier, in the liquid phase, the catalyst is pre-treated with some other nitrile (e.g. an aliphatic or aromatic nitrile) in presence of H2. Claimed process minimises risk of decomposition of catalyst.

Abstract: To remove phosgene from off-gases, the former is reacted in a washing zone with a liquid which contains or is composed of compounds of the formula where R1 and R2 are identical or different and are each aliphatic or cycloaliphatic alkyl of 1 to 8 carbons, or R1 and R2 are -(CH2)n- where n is 4 or 5, R3 is hydrogen or aliphatic or cycloaliphatic alkyl of 1 to 6 carbon atoms, or R1 or R2 and R3 are -(CH2)m- where m is 3, 4 or 5. The liquid can be regenerated by the addition of water, and the regenerated liquid can be returned to the washing zone.
