  • Process for the preparation of polyphosphates of organic bases
    Patent number: 7345168
    Abstract: A simple and economical process for the preparation of polyphosphates of organic bases consists of reacting a mixture of phosphorus pentoxide and at least one organic nitrogen base with at least one compound which releases water accompanied by decomposition under the prevailing conditions in such a molar ratio that upon decomposition of the water-releasing compound at most essentially 2 mol. water are produced per mol. phosphorus pentoxide. Thus-prepared polyphosphates are particularly suitable as flame-protection agents for plastics.

  • Derivative of phosphoric acid ester salt or phosphoric acid ester adduct or mixtures thereof, method for the production thereof and their use
    Patent number: 7214811
    Abstract: A derivative of phosphoric acid ester salt or adduct or a mixture thereof is obtained from a reaction product, polycondensed with at least one aldehyde, of at least one polyol phosphoric acid ester with at least one organic nitrogen base. The derivative is advantageously used as a flame-inhibiting and/or intumescent treatment in plastic mouldings, on porous carriers or in paint or coating systems. The production of the derivative or a mixture thereof by reacting at least one polyol with phosphorus pentoxide and reacting the polyol phosphoric acid ester obtained in that way with at least one organic nitrogen base forming a phosphoric acid ester salt or adduct, is characterized in that the amount of phosphorus pentoxide required for the esterification operation is suspended in an amount of the ester or ester mixture to be produced, then at a temperature in the range of 20–180° C.
