    Abstract: 1,139,634. Glycol monoesters. BADISCHE ANILIN- & SODA-FABRIK A.G. 27 May, 1966 [29 May, 1965; 23 Oct., 1965], No. 23886/66. Heading C2C. Carboxylic acid monoesters of aliphatic, cycloaliphatic or arylaliphatic vicinal diols are obtained by reacting a carboxylic acid with an epoxide derived from an aliphatic, cycloaliphatic or arylaliphatic olefine at elevated temperature in the presence of a thioether or a sulphoxide. Suitable carboxylic acids are aliphatio mono- or poly-carboxylic acids, cycloaliphatic, araliphatic and aromatic mono- or poly-carboxylio acids. Suitable epoxides are aliphatic, cycloaliphatic and araliphatic epoxides. Specified thioethers and sulphoxides are those of the formulµ R-S-R 1 and R-SO-R 1 wherein R and R 1 represent organic radicals and they may together form a ring. The thioethers may be formed in situ from H 2 S, mercaptans or thiophenols and alkylene oxide reactant. The sulphoxides may also be formed in situ from thioethers and oxidizing agents. Examples are given for the production of glycol monoacetate, glycol monoacrylate, glycol monobenzoate, bis- (hydroxyethyl)-terephthalate and the monoglycol ester of terephthalic acid.

    Abstract: Prepn. of glycine nitriles of formula R3R4N.CR5R6.CN (I) comprises reacting amnes R3R4NH (III) with carbonyl cpds R5COR6 (IV) and HCN in presence of water for 0.1-4 hrs. at 0-80 degrees C. The condn. of HCN never exceeds 0.9 wt. % of the reaction mixt. In the formulae, R3-6 are aromatic, cycloaliphatic or araliphatic gps.; R3 and R4 may together complete a heterocycle; R4-6 may also be H, and R5 and R6 may also be aliphatic, and when R5 and/or R6 is aliphatic aromatic, cycloaliphatic or araliphatic, then R3 and R4 can also be aliphatic. Pref. the products where R3-6 are aromatic gps., R5 and R6 may also be H, aliphatic, cycloaliphatic or araliphatic, and R4 may be H, are subsequently treated with an acid at pH 1-7. (I) are stabilisers; intermediates for dyes (e.g. indigo) fungicides, bactericides, textile auxiliaries and antigelling agents; and by saponification give glycine salts useful as selective adsorbents for CO2, SO2 and H2S, and by hydrogenation give assymetric diamines useful for making pharmaceuticals and plant protection agents. Cf. the process of DT 1543342. This method is simpler and more economic giving better yields of purer products. Water pollution and formation of resinous by-products are minimised, and subsequent acid treatment obviates expensive purification steps and avoids losses of solvent.
