Abstract: A product consisting essentially of an acid orthophosphoric acid ester salt and containing at most about 1 weight % of water is made. The ester group R contains 1 to 50 carbon atoms, and the salt-forming cation M is a mono- or bivalent metal ion or an ammonium ion. To make the product, molar proportions of P2O5 and of a compound of the general formulae M2O, M2CO3, MO or MCO3 are reacted at about 0 DEG to 150 DEG C, with thorough agitation, with 2/m mol of an at least partially liquid or molten organic hydroxyl compound of the general formula R(OH)m, in which formulae the substituents M and R have the meanings given above and m is a number of 1 to 4. The reaction is terminated and the reaction product is cooled.

Abstract: STABILIZED RED PHOSPHORUS AND PROCESS FOR MAKING IT Production of stabilized pulverulent red phosphorus. The phosphorus so stabilized comprises a homogeneous blend of red phosphorus particles with a size of at most about 2 mm and a metal compound of the second or third group of the Periodic System as an oxidation stabilizer, wherein the metal compound is the aluminum, calcium or zinc salt of a phosphinic acid of the general formula in which R1 and R2 each stand for an alkyl, cycloalkyl, aryl or aralkyl group having 1 to 20 carbon atoms, the metal compound being present in the homogeneous blend in a proportion of about 0.5 to 5 weight %.

Abstract: The invention relates to a process wherein an alcohol and/or phenol is reacted with phosphorus pentasulfide in the presence of a catalyst which is selected from (a) phosphonium salts of the general formula: I (b) ammonium salts of the general formula: II (c) phosphine oxides of the general formula: III (d) phosphine sulfides of the general formula: IV (e) phosphinic acid derivatives of the general formula: V In formulae I through V, the substituents R1, R2, R3 and R4 each stand for identical or different alkyl-, aryl-, alkaryl- or aralkyl- groups having from 1 to 22 carbon atoms. A stands for an inorganic or organic acid, and X and Y, respectively, stand for both oxygen and sulfur, and M stands for a monovalent metal or oxygen.

Abstract: 1519929 Red phosphorus HOECHST AG 27 May 1977 [17 July 1976] 22500/77 Heading C1A Stabilized pulverulent red phosphorus comprises a homogeneous blend of red phosphorus particles with a size of at most about 2mm and as an oxidation stabilizer a metal compound of the second or third group of the Periodic System, the metal compound being the aluminium, magnesium, calcium or zinc salt of an alkyl-, cycloalkyl-, aryl- or aralkyl-phosphonic acid having 1 to 20 carbon atoms, the metal compound being present in the homogeneous blend in a proportion of 0À5 to 5 weight per cent. Red phosphorus particles may-be intimately blended with 0À5 to 5 weight per cent, based on red phosphorus, of an alkyl-, cycloalkyl-, aryl- or aralkyl-phosphonic acid having 1 to 20 carbon atoms; the blend suspended in water and the suspension heated to 60 to 95‹ C.; the suspension gradually admixed with at least stoichiometric proportions of an aqueous solution of a water-soluble aluminium, magnesium, calcium or zinc salt to cause precipitation of the respective phosphoric acid salt from the aqueous suspension at a pH of 3À0 to 6À0 and preferably at a temperature of from 80 to 90‹ C.; the resulting mixture filtered, and the filter residue dried at elevated temperature, suitably at 80 to 130‹ C., and if desired, under reduced pressure. Preferred water-soluble salts are Al 2 (SO 4 ) 3 .18H 2 O, Ca(NO 3 ) 2 .4H 2 O, ZnSO 4 .7H 2 O and MgSO 4 .7H 2 O, which may be used in the form of 5 to 20 weight per cent aqueous solutions. The aluminium salt is suitably precipitated at pH 3À0 to 3À5 and the salts of the other metals at pH 5À0 to 6À0.
