Изобретение относится к способу стабилизации кристаллического органического фосфонита или фосфита от воздействия гидролиза, отличающееся тем, что нагретую до 50 - 100oС смесь, содержащую фосфит или фосфонит, растворитель или смесь растворителей и 0,1 - 100 вес.% (по отношению к фосфиту или фосфониту) амина, вводят в виде гомогенного расплава в жидкую кристаллизационную среду, температуру которой во время введения добавки поддерживают на уровне, лежащем на 10 - 70oС ниже температуры расплава. Стабилизированные фосфиты или фосфониты отличаются исключительно высокой стойкостью к гидролизу и обладают хорошей стабильностью даже при хранении в условиях высокой влажности воздуха. Они могут эффективно применяться в качестве стабилизаторов органических материалов от вредного воздействия тепла, кислорода и/или света.The invention relates to a method for stabilizing a crystalline organic phosphite or phosphonite against hydrolysis, exposure, characterized in that heated to 50 - 100 o C a mixture comprising phosphite or phosphonite, a solvent or solvent mixture and 0.1 - 100 wt% (relative to the phosphite. or phosphonite) amine, is introduced in the form of a homogeneous melt into a liquid crystallization medium, the temperature of which during the introduction of the additive is maintained at a level lying at 10 - 70 o C below the temperature of the melt. Stabilized phosphites or phosphonites are extremely resistant to hydrolysis and have good stability even when stored in high humidity. They can be effectively used as stabilizers of organic materials from the harmful effects of heat, oxygen and / or light.
