Abstract: An improved process for the continuous production of alpha -chloropropionic acid by reaction of propionic acid with chlorine in the presence of halides or acid halides of the elements phosphorus and sulfur at elevated temperature, the improvement consisting in carrying out the reaction in the presence of alpha -chloropropionic acid as solvent and distilling the resultant reaction mixture using the gas formed in the reaction as carrier gas. alpha -chloropropionic acid is used for the production of plant protection agents.

Abstract: Alkanes substituted by chlorine atoms and/or sulfochloride groups are prepared by reacting alkanes with chlorine, with or without sulfur dioxide, in a particular throughput ratio, in a reaction chamber inclined to the horizontal, the starting materials being passed through the reaction chamber in co-current, from below. The substituted alkanes or paraffins obtainable by the process of the invention are pesticides, plasticizers, solvents and starting materials for the preparation of such products, as well as of fat liquors, detergents, lubricating oils, synthetic resins and slip agents.

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.

Abstract: The new 1-monochloro- and 1,1-dichloro-prop-2,3-ene-3-sulfonic acids and their metal salts, and a process for their manufacture by reacting chloropropanesulfonic acid compounds with alkali metal carbonates, alkali metal bicarbonates and/or alkaline earth metal hydroxides at from 5 DEG to 100 DEG C to give 1-chloro-prop-2,3-ene-3-sulfonates which may then be reacted with acid compounds in a second step.
