Abstract
1276822 Preparing solid aliphatic amino di(alkylene phosphonic acids) MONSANTO CO 4 Sept 1970 42483/70 Heading C2P A solid aliphatic amino di(alkylene phosphonic acid) is obtained from a crude liquid reaction product obtained by reacting together a primary amine, an aldehyde or ketone, and orthophosphorous acid by containing the said reaction product in liquid form with at least intermittent agitation, with at least twice its weight of a liquid diluent maintained at a temperature of at least just above the freezing point of the reaction product, thereby forming a slurry in the liquid phase of a solid phase containing the said amino di(alkylene phosphonic acid), heating the slurry to from 80‹ to 100‹ C., maintaining it at that temperature for at least one minute, and separating the solid phase from the slurry. Specified liquid diluents are water, methanol, ethanol, n or iso-propanol, acetone and methyl ethyl ketone. If desired the liquid slurry may be cooled, e.g. to 70‹ C. or lower, e.g. 20‹ C., before separation of the solid phase which may be effected by filtration or centrifugation. The liquid slurry before separation of the solid phase may be admixed with an aqueous solution containing an alkali metal hydroxide to form the alkali metal salt of the phosphonic acid in solution and the latter may then be contacted with activated carbon to remove colour-forming impurities. The activated carbon is then separated from the purified salt solution and the solution then treated with a mineral acid to convert the salt to the free acid. The activated carbon may be contacted with the salt solution in either a batch-wise or continuous manner and may be in powder.or granular form.
