Description
Эфиры кислот трехвалентного фосфора и лигнина в литературе не описаны.Esters of acids of trivalent phosphorus and lignin are not described in the literature.
Предложенный способ получени фосфитов и фосфииитов заключаетс в том, что лигнин подвергают взаимодействию с эфирами или амидами кислот трехвалентного фосфора нри нагревании до ПО-150°С.The proposed method for the preparation of phosphites and phosphonites is that the lignin is reacted with esters or amides of trivalent phosphorus acids when heated to PO-150 ° C.
Процесс можно вести в присутствии катализаторов (щелочные реагенты).The process can be conducted in the presence of catalysts (alkaline reagents).
Пример 1. Фосфорилирование лигнина диметилфосфитом.Example 1. Phosphorylation of lignin with dimethylphosphite.
В перегонный прибор помепдают 5 г высушенного лигнина, 25 г диметилфосфита и маленький кусочек метилата натри , и нагревают смесь в атмосфере инертного газа 1,5 час при 130°С и 1,5 час при 150°С. После этого вещество фильтруют и промывают эфиром (можно метанолом, бензолом и т. д.). Выход 5,1 г. Содержание фосфора 7,42о/о. Из фильтрата перегонкой выдел ют не вступивщий в реакцию фосфит.5 g of dried lignin, 25 g of dimethylphosphite and a small piece of sodium methoxide are put into the distillation unit, and the mixture is heated in an inert gas atmosphere for 1.5 hours at 130 ° C and 1.5 hours at 150 ° C. After that, the substance is filtered and washed with ether (can be methanol, benzene, etc.). Output 5.1 g. The content of phosphorus 7,42o / o. Unreacted phosphite is recovered from the filtrate by distillation.
Пример 2. Фосфорилирование лигнина моноэтилметилфосфинитом.Example 2. Phosphorylation of lignin with monoethylmethyl phosphinite.
В аиалогичных услови х из 5 г лигнина и 25 г фосфинита получают 5,2 г продукта с содержанием фосфора 8,150/0.Under similar conditions, out of 5 g of lignin and 25 g of phosphinite, 5.2 g of product with a phosphorus content of 8.150 / 0 are obtained.
Пример 3. Фосфорилирование лигнина гексаэтилтриамидом фосфористой кислоты.Example 3. Phosphorylation of lignin with hexa ethyl triamide phosphorous acid.
В аналогичных услови х, но при 5-часовом нагревании до 110°С 5 г лигнина и 30 г амида получают 5,5 г продукта с содержанием фосфора 6,70/0.Under similar conditions, but under 5-hour heating to 110 ° C, 5 g of lignin and 30 g of amide give 5.5 g of product with a phosphorus content of 6.70 / 0.
