METHOD FOR OBTAINING AMINO-CONTAINING ARYLOXYCYCLOPHOSPHAZENES IN THE MASS OF AMINES Russian patent published in 2022 - IPC C07F9/659 

FIELD: material engineering.

SUBSTANCE: invention relates to a method for producing amino-containing derivatives of cyclophosphazenes in the mass of amines, which can be used for the manufacture of polymer composite materials with reduced flammability. The method involves the interaction of formylphenoxycyclophosphazenes of the general formula (component A), , where m is from 3 to 10, n is from 1 to 2m inclusive, X and Y are either -H, or -Cl, or -Br, or -F, or -I, or -CH₃, or -H₃, with an excess of an aliphatic or aromatic amine containing more than one amino group, or a mixture of these amines (component B) with a mass ratio of components A and B equal to 1÷40 : 60÷99, in the presence of an auxiliary substance (component C), which is a mineral salt, in an amount of 20, wt.%, of the total mass of components A and B, maintaining the temperature so that the reaction mass is in a liquid state.

EFFECT: proposed method eliminates the use of toxic and combustible organic solvents, additional stages of solvent regeneration, isolation and purification of target products.
