    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: Production of poly- Alpha -oxyacrylic acid by contacting a solution of Alpha -chloracrylic acid with one or more radicalyielding polymerization catalysts, heating and thereby hydrolyzing the resulting poly- Alpha -chloracrylic acid in queous solution with the resultant precipitation of solid polyAlpha -oxyacrylic acid and separating the poly- Alpha -oxyacrylic acid. More particularly, and aqueous Alpha -chloracrylic acid solution is contacted with the radical-yielding polymerization catalysts for a period of at least 30 minutes and, while leaving the resulting poly- Alpha -chloracrylic acid unseparated, it is heated for a period of at least 1 hour to temperatures within the range 80* and 110*C.

    Abstract: PRODUCTION OF 2-(HALOGENOFORMYL)-VINYL!-ORGANYL- PHOSPHINIC ACID HALIDES 2-(halogenoformyl)-vinyl!-organyl-phosphinic acid halides of the general formula in which R1 stands for an alkyl group having 1 to 8 carbon atoms, an aryl group or a substituted derivative of these groups, R2 stands for a hydrogen atom, an alkyl group having 1 to 8 carbon atoms. an aryl group or a substituted derivative of these groups, and X stands for a chlorine or bromine atom, are produced. To this end, a 2 halogenoacrylic acid or a substitution product thereof of the general formula in which R2 and X have the meanings given above, is reacted at 15 - 90.degree.C with an organyldihalogenophosphane of the general formula R1 - PX2 in which R1 and X have the meanings given above.

    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.
