Abstract: Use of iminodiacetic acid derivs. (I) as complexing agent or builder in alkaline cleaning formulations for the drinks and food industries is new. R=H, 1-4C alkyl, CH2CH2X, CH2CHOHX, -C(CH2OH)2X or CHY(-CH2)-nX; X= COOH (opt. as alkali metal or (substd.) ammonium salt) or CONH2 (opt. N substd.); Y = COOH (opt. in salt form as X); Z = H or OH; n = 1 or 2. Also new is an aq. cleaning formulation contg. 0.05-30 wt.% (I); 2-50 wt.% alkali metal hydroxide, carbonate and/or silicate, and 1-30 wt.% surfactant. USE/ADVANTAGE - The compsns. are used to clean bottles and machinery used in dairies, breweries or industries which mfr. and process preserved foods, baked goods, sugar, fat and meat. They give good results for removal of e.g. Ca salt deposits, hop resins, fat and dough residues etc. Unlike known iminodiacetic acid derivs., (I) can be formulated without organic solvents and also have an improved spectrum of activity. (I) are extraordinarily effective chelating agents for alkaline earth metals, e.g. Ca, and have extremely high Ca-binding capacity. They are readily biodegradable and have low toxicity.

Abstract: Prepn. of N-alkanoyl-polyhydroxyalkylamines of formula Z-N(R1)C(=O)R2 (I) comprises reacting polyhydroxyalkylamines of formula Z-NH-R1 (II) with alkyl esters of carboxylic acids of formula R3-O-C(=O)-R2 (III), in presence of a basic catalyst. In the prepn. of (a) the total amt. of (III) is heated to 90-130 deg.C and an aq. soln. of (II) is added, with the water introduced being continuously removed by distn. (b) the catalyst is added to the fine suspension of (II) in (III) and conversion to (I) is carried out at 70-100 deg.C with continuous removal by distn. of the alcohol, R3-OH formed and (c) conversion is in absence of organic solvents. In the formulae, Z = polyhydroxyalkyl residue of a mono- or oligo-saccharide; R1 = H or 1-8C alkyl; R2 = 1-21C alkyl; R3 = 1-4C alkyl. USE/ADVANTAGE - (I) are surfactants, used in washing and cleaning compsns. Colourless or light coloured prods. with a high (I) content and smaller amts. of starting materials and by-prods. are obtd. needing no further purification. Formation of clumps and deposits in the reactor is avoided, and the process can be used on the large scale.
