Title: Compounds and compositions of low hygroscopicity derived from sodium aluminium phosphate
IPC: C01B25/45
Filed: 1962-10-24
Abstract: Compounds and compositions of low hygroscopicity are produced by treating sodium aluminium phosphate with an ionizable potassium compound.  The compounds may contain 0.1 to 37% of potassium and the compositions from 0.5 to 20% of the potassium compound. Neither will increase in weight by more than 20% on exposure to 35 DEG  C. and 75% relative humidity for 140 hrs. Suitable potassium compounds may have organic or inorganic anions and may be soluble in organic or inorganic solvents, e.g. 50% water-alcohol mixture.  Salts specified are KCl, KBr, KI, KF, K3PO4, potassium tartrate, potassium acid tartrate, potassium acid phthalate, potassium acetate, KNO3, K2SO4, KH2PO4. Sodium aluminium phosphate may be produced by adding to phosphoric acid aluminium or an aluminium compound e.g. Al2O3 or Al(OH)3 in stoichiometric excess and NaOH or Na2CO3 sufficient to provide a 1:3-Na:Al ratio. The potassium ions may be introduced at any stage during or after preparation.  A solution of the potassium ions may be sprayed on to crystals of sodium aluminium phosphate in a denze fluidized bed, in a mildly agitated bed, e.g. a rotary kiln, conveyer or drier, or a thin static bed.  The potassium ions may be concentrated within the surface of the sodium aluminium phosphate crystals by slurrying the preformed crystals in a potassium salt solution. The amount of potassium ion introduced in this way may be increased by pulverizing the treated crystals before a second treatment. The sodium aluminium phosphate may be mixed dry with a potassium compound. For example, KCl milled and screened to - 400 mesh, sodium aluminium phosphate and glass beads were mixed under vacuum in a flask rotated about a horizontal axis.ALSO:Baking acid compounds and compositions, of low hygroscopicity are produced by treating sodium aluminium phosphate with an ionisable potassium compound.  The compounds may contain 0.1-37% of potassium and the compositions 0.5-20% of the potassium compound.  The potassium may be spread uniformly throughout the crystals of sodium aluminium phosphate or concentrated at their surfaces.  The compounds and compositions may have neutralizing values of 96-103 and may be used with sodium bicarbonate in baked goods.  Potassium compounds specified are: KCl, KBr, KI, KF, K3PO4, potassium tartrate, potassium acid tartrate, potassium acid phthalate, potassium acetate, KNO3, K2SO4, KH2PO4.  In examples the compounds of the invention are incorporated in doughnut dough, water and milk biscuit doughs, a cake mix containing flour, milled sugar, non-fat dry milk, salt, ground soda, gelatinised wheat starch, corn sugar, mono-and di-glyceride, lactic acid, egg white and water, and a pancake mix also containing hardwheat flour, softwheat flour, corn flour, rye flour, wheat starch, salt, corn sugar, soda, eggs and milk.

Title: Improved method of making phenol modified amino condensation resins
IPC: C08G14/06
Filed: 1962-11-12
Abstract: A colourless phenol-modified amino condensation resin is made by neutralising an aqueous solution of an aldehyde with a carbonate of Mg, Ca, Si, Ba or Zn, reacting urea with the resulting solution, adding phenol to the aqueous solution of the precondensate thus produced and reacting the mixture to the desired degree of condensation. The preferred molar ratio of (1) urea/phenol is from 1:0.2 to 1:1, (b) urea/aldehyde is from 1:0.9 to 1:1.2.  Aldehydes specified are formaldehyde, paraformaldehyde, trioxymethylene, hexamethylenetetramine and acetaldehyde.  Urea can be partially replaced by thiourea, dicyandiamide or melamine.  Moulding compositions can be made by impregnating fillers, e.g. a -cellulose, wood flour, walnut shell flour, asbestos and cloth cuttings, with aqueous solutions of the resins, and subsequently drying the impregnated fillers. Dyes, pigments, lubricants and hardening agents may also be added.  In a typical example (1) formalin, which had been neutralised with MgCO3, was reacted with urea at 90 DEG C, and then with phenol at a pH of 6.6 to 6.8, and the condensation was completed after 1 hour at 80 DEG C.  The pH of the resulting solution was adjusted to 6.9 by adding aqueous formic acid and then to 5.4 by adding aqueous ammonium thiocyanate, and used for impregnating a -cellulose. Uses: for making laminated articles; in treating paper; as components of lacquers; coating compositions; and adhesives.
