Description

Metal phosphate resins process for their preparation ISRAEL MINING INDUSTRIES FOR RESEARCH AND DEVELOPMENT This invention consists in insoluble synthetic resins being polymers or copolymers derived from metal diallyl phosphates of the formula where is a metal having a valency of from 1 to 4 and may also be and n is an integer of from 1 to Typical representatives of monovalent metals are the alkali metals divalent metals include a wide range of metals of different groups of the Periodic Table of alkaline earth metals such as transition such as and example of tervalent metals is aluminium and of valent metals is Metal diallyl phosphate resins according to the tion are valuable In addition they have been found to poesees a property which has been quite that they can absorb water selectively from organic wet gases and the and that they can readily be freed from the absorbed water with a small expenditure of energy by various different such as retransfer of the water to a solvent This property can be used either for the tion of the matter or for the recovery of pure water as described in an Israel Patent Specification They also exhibit selective absorption with respect to organic eolvents and may therefore be used for the separation of such solvents from each for poly diallyl can be used for the separation of mercaptanee from a Attempts made hitherto to prepare diallyl phosphate resins have Efforts to prepare resins with an approximately similar structure have been reported by Kennedy at This consisted in saponifying polytriallyl phosphate with aqueous alkali metal then acidulating the reaction mixture and neutralizing the resultant polyacid with inorganic salt of the desired though one of the allyloxy groups of the polytriallyl phosphate is more readily saponifiable than the remaining diallyl phosphates could not be produced in this The invention thus provides a process for the preparation of the new metal or ammonium polydiallyl phosphates and their which is a initiated merization or eopolymerisation of monomeric metal diallyl phosphate by itself or together with another monomer such as triallyl phosphate or Polymerization can be initiated by the irradiation of the reaction mixture with ultraviolet rays or any other conventional means for producing free The invention is illustrated by the following Examples to which it is not Example 1 10 g of sodium diallyl phosphate was refluxed with stirring in 20 ml of benzene containing g of benzoyl peroxide as an initiator at about under a nitrogen atmosphere for The mixture obtained was washed first with ethyl then with and whereby g of colourless insoluble polymeric sodium diallyl phosphate resin was It contained and organic such as ether and Its solubility in water was less than by In a aqueous no solubility could be Example 2 10 g of sodium diallyl phosphate was heated with stirring in 30 ml of xylene containing g of peroxide as an initiator under a slow stream of dry nitrogen at for 24 while being constantly exposed to The resultant mixture was further treated as in Example whereby 5 g of dry polymeric sodium diallyl phosphate resin was The properties of the resins were the same those of the resin obtained according to 3 Portions of the polymeric sodium diallyl phosphate obtained in accordance with Example 2 were mixed with aqueous solutions of aluminium or ferric After approximately minutes the mixtures were washed with water until and The solids obtained were analyzed and found to contain respectively aluminium and Example 4 A solution of 10 g of sodium diallyl phosphate in 5 ml of water containing ml of a aqueous solution of hydrogen peroxide was heated under nitrogen at for 30 hours while being irradiated by a source of After washing and 5 g of polymeric sodium diallyl phosphate resin was whose properties were the same as those of the resin obtained according to Example 1 ν Example 5 a solution of cobaltous diallyl phosphate in containing benzoyl peroxide in an amount of by weight of the monomer was refluxed for 12 hours in an inert The resultant benzene insoluble formed was washed and dried as described in Example This resin thus produced is blue when dry and turns upon contact with Similar colour changes were not observed upon contacting this resin with dry Example 6 A aqueous solution of diallyl was with under a nitroge The polymer obtained purified as described in Example It was insoluble in furan and If the of magnesium diallyl phosphate was carried out under the conditions of Bxample the polymer was virtually the same as described in the preceding Example 7 9 g of cobaltous diallyl phosphate and 1 of triallyl phosphate were copolymerized under the conditions described in Example The resultant resin was equally insoluble in common organic solvents as well as in With the teristic colour change described in Bxample 5 was Example 8 10 g of silicon diallyl phosphate in 30 ml of benzene and g of peroxide were refluxed under for five The viscosity of the solution increased 6 ethyl Example 10 g of titanium phosphate dissolved in 50 ml of containing also of benzoyl was refluxed under a nitrogen atmosphere for 10 The product obtained was washed with hydrofuran and The resinous product was insoluble in common organic solvents as well as in insufficientOCRQuality
