Abstract
1479381 Hydroxy propylene polynitrilo polymethylene phosphonic acids; 1,3-diamino-2- hydroxypropane PHILIP A HUNT CHEMICAL CORP 4 Aug 1975 [30 Sept 1974] 32478/75 Headings C2P and C2C [Also in Division C1] Polymethylene phosphonic acids have the formula where n = 1-5 together with their alkali metal, ammonia, amino and hydroxyalkylamine salts. The compounds are prepared by reacting PCl 3 with the appropriate amine/formaldehyde condensation product followed by hydrolysis. Preferred compounds are those in which n = 1-4 and also compositions containing compounds in which n= 1-3. The compounds are used to chelate metal ions having a valency of 2 or more, particularly to inhibit the formation of calcium sulphate precipitate in aqueous systems. 1,3 - Diamino - 2 - hydroxypropane is prepared from ammonium hydroxide and epichlorhydrin followed by distillation. The crude reaction product is a mixture of amines of formula where n = 1-5.
