    Abstract: PRODUCTION OF N-SUBSTITUTED 2-CARBAMOYL PHOSPHINIC ACIDS. Production of N-substituted 2-carbamoyl phosphinic acids of the general formula: (I) in which R1 stands for an alkyl group having 1 to 4 carbon atoms or an aryl group; R2 and R3 stand independently of each other for an alkyl group having 1 to 4 carbon atoms, an aryl group- or a hydrogen atom; R4 stands for an alkyl group having 1 to 18 carbon atoms, an aryl group or a hydrogen atom; and R5 stands for an alkyl group having 1 to 18 carbon atoms or an aryl group. More specifically, a 2-chloroformyl phosphinic acid chloride of the general formula (II) is reacted at 120 to 170.degree.C with an amine of the general formula (III) and resulting N-substituted 2-carbamoyl phosphinic acid chloride of the general formula (IV) the latter compound being obtained while hydrogen chloride is split off, is hydrolyzed with water.

    Abstract: Water-soluble salts of acid carboxylic acid esters of bivalent aliphatic or olefinically unsaturated carboxylic acids or hydroxycarboxylic acids and at least trihydric aliphatic alcohols are used as builders for detergent and cleansing agents. Each hydroxylic group of the alcohol or optionally of the carboxylic acid has a carboxylic acid-molecule attached thereto.

    Abstract: 1397957 Detergents containing builders HOECHST AG 14 Sept 1972 [24 Sept 1971] 42706/72 Heading C5D [Also in Division C2] Builders for detergent and cleansing agents comprise water-soluble salts of acid carboxylic acid esters prepared by reacting at least trivalent, 6-10C, aliphatic olefinically unsaturated carboxylic acids or hydroxy-carboxylic acids with aliphatic alcohols (3-6 OH groups), and in which each hydroxylic group of the alcohol and optionally the hydroxycarboxylic acid is esterified with a carboxylic acid molecule. Citric, aconitic, tricarballylic, dihydroxy-tricarballylic, nitrotriacetic and ethylenediamine-tetracetic acids may be used with glycerol, erythritol, pentaerythritol, mannitol, sorbitol or sugar alcohol (4-6 C) and the salts are of alkali metal or ammonium ion. A proportion of 10-80% by weight of salts may be used and then ion-active and/or non-ionic tensides and further conventional additives may be present. Examples describe the use of builders prepared from glycerol, sorbitol or pentaerythritol with nitric acid used with dodecylbenzene sulphonate, tallow fatty alcohol and hardened tallow soap, and also with additional magnesium silicate, sodium silicate, sodium perborate, sodium sulphate and tylose in detergent wash liquors.

    Abstract: The invention provides novel oligomers and/or polymers containing carboxylic and hydroxylic groups - the latter groups being partially lactonized, if desired - and a predominant proportion of C-C bonds in their principal chain. The oligomers and/or polymers are produced by hydrolyzing halogenated copolymers which have substantially between 5 and 60 weight % of halogen therein and a principal chain based on structural units, in any desirable sequential arrangement, of the following general formulae I and II or I and III in which X, Y and Z stand for a hydrogen and/or halogen atom with the proviso that at least one of the X, Y and Z substituents stands for a halogen atom, R stands for a carboxyhalide radical, a carboxylic group, ester group, nitrile group or anhydride group, and the mole fraction m stands for a number greater than zero and smaller than 1.
