Description

Предложен способ получени  окисей ди-(оксиметил)-алкилфосфинов взаимодействием ди-(оксиметил)-алкилфосфинов (на примере ди-(оксиметил )-метилфосфина) с разбавленной перекисью водорода. Способы получени  ди-(оксиметил)-алкилфосфинов до насто щего времени не были известны. Соединени  в литературе не описаны.A method is proposed for producing oxides of di- (hydroxymethyl) alkylphosphines by reacting di- (hydroxymethyl) alkylphosphines (by the example of di- (hydroxymethyl) methylphosphine) with dilute hydrogen peroxide. Methods for preparing di- (hydroxymethyl) alkylphosphines have not been known to date. Compounds are not described in the literature.

Синтезированный препарат может найти применение в качестве мономера при изготовлении негорючих полимеров.The synthesized product can be used as a monomer in the manufacture of non-combustible polymers.

Пример. К 26,4 мл 6%-ного раствора перекиси водорода (уд. вес 1,021 при 19°, вес 25,7 г-0,045 мол ), охлажденного льдом, при непрерывном перемешивании постепенно приливают раствор 4,9 г сырого ди (оксиметил)-метилфосфина, полученного из параформальдегида и метилфосфина , в 0 мл воды. Водный раствор отфильтровывают и фильтрат упаривают в вакууме до посто нного веса.Example. To a 26.4 ml of 6% aqueous hydrogen peroxide solution (sp. Weight 1.021 at 19 °, weight 25.7 g-0.045 mol) cooled with ice, with continuous stirring, a solution of 4.9 g of crude di (hydroxymethyl) - methylphosphine, obtained from paraformaldehyde and methylphosphine, in 0 ml of water. The aqueous solution is filtered and the filtrate is evaporated in vacuo to constant weight.

При этом получаетс  4,65 г (98,5%) окиси ди-(оксиметил)-метилофосфина в виде в зкой сиропообразной жидкости, при охлаждении и трении полностью кристаллизирующейс  в форме бесцветных игольчатых кристаллов, расплывающихс  от влаги воздуха.This yields 4.65 g (98.5%) of di- (oxymethyl) -methylphosphine oxide as a viscous syrupy liquid, which, when cooled and rubbed, completely crystallizes in the form of colorless needle-like crystals, spreading from the moisture of the air.

Полученное вещество не перегон етс  в вакууме 3 мм рт. ст. при нагревании до 200° и не разлагаетс  при этом. Оно растворимо в воде и спирте, нерастворимо в бензоле эфира.The resulting material is not distilled under a vacuum of 3 mm Hg. Art. when heated to 200 ° C and does not decompose. It is soluble in water and alcohol, insoluble in benzene ether.
