| titleOfInvention | Method for the manufacture of organo substituted phosphonium salts |
| abstract | Substituted phosphonium salts such as tetrakis(hydroxymethyl)phosphonium chloride are prepared by reacting a metal phosphide selected from the group consisting of lithium phosphide, sodium phosphide, potassium phosphide, beryllium phosphide, magnesium phosphide, calcium phosphide, strontium phosphide, barium phosphide, boron phosphide, aluminum phosphide, gallium phosphide, and zinc phosphide, with an aldehyde having from 1 to 12 carbon atoms, the proportion of the aldehyde being at least 4 moles per gram atom of the phosphorus in the said phosphide. The reaction is conducted with at least one and a half moles of water per gram atom of phosphorus in the said phosphide and at least one mole of mineral acid being present per gram atom of phosphorus in the said phosphide, with or without a catalyst, and in the presence of an inert gas atmosphere. The products are fire retardants. |
