Description
СПОСОБ ПОЛУЧЕНИЯ СРЕДНИХ ФОСФИТОВ АМИЛОПЕКТИНАMETHOD OF OBTAINING AMYLOPECTIN MEDIUM PHOSPHITES
1one
Изобретение относитс к способу получени неизвестных ранее средних фосфитов амилопектина (полисахарида, вход щего в состав крахмала).The invention relates to a method for producing previously unknown medium phosphites of amylopectin (a polysaccharide incorporated into starch).
Средние фосфиты амилопектина обладают высокой реакционной способностью и могут быть использованы как исходные вещества в синтезе новых ионообменников и физиологических активных вендеств с пролангирующим действием.Medium phosphites of amylopectin have a high reactivity and can be used as starting materials in the synthesis of new ion exchangers and physiological active species with a prolonging effect.
Описываемый способ основан на известной реакции фосфорилировани с помощью диалкилкарбамоилфосфитов .The described method is based on the known phosphorylation reaction using dialkylcarbamoyl phosphites.
Способ заключаетс в том, что амилопектин подвергают взаимодействию с диалкилкарбамоилфосфитом с последующим выделением пелевого продукта известными приемами.The method consists in that amylopectin is reacted with dialkylcarbamoyl phosphite, followed by isolation of the pellet product by known methods.
Процесс провод т в среде органического растворител , например, диметилформамида при комнатиой температуре.The process is carried out in an organic solvent medium, e.g. dimethylformamide, at room temperature.
Пример 1. К 0,5 г абсолютно сухого амилопектина добавл ют 0,65.г диметилкарбамоил-1 ,3-бутиленфосфита и смесь выдерживают в атмосфере сухого воздуха 48 час при комнатной температуре. Полученный продукт обрабатывают сухим эфиром не менее трех раз и сушат в вакууме. Содержание фосфора в нем составл ет 0,8%.Example 1. To 0.5 g of absolutely dry amylopectin, 0.65 g of dimethylcarbamoyl-1, 3-butylene phosphite is added and the mixture is kept in a dry air atmosphere for 48 hours at room temperature. The resulting product is treated with dry ether at least three times and dried in vacuum. Its phosphorus content is 0.8%.
Пример 2. 0,5 г абсолютно сухого амилопектина в 10 мл растворител (диметплформамида или тетрагидрофурана) оставл ют при комнатной температуре на 4 час дл набухани амилопектина. Затем к смеси прибавл ют 1,95 г диметилкарбамоил-1,3-бутиленфосфита и выдерживают 48 час при комнатной температуре в атмосфере сухого воздуха. Далее полученный продукт обрабатывают согласно примеру 1.Example 2 0.5 g of absolutely dry amylopectin in 10 ml of solvent (dimethylformamide or tetrahydrofuran) are left at room temperature for 4 hours to swell amylopectin. Then, 1.95 g of dimethylcarbamoyl-1,3-butylene phosphite is added to the mixture and incubated for 48 hours at room temperature in a dry air atmosphere. Next, the resulting product is treated according to example 1.
Полученный продукт содержит 4,4% фосфора в случае ведени реакции в среде диметилформамида и 2,4% - в случае ведени реакции в среде тетрагидрофурана.The resulting product contains 4.4% phosphorus in the case of conducting the reaction in dimethylformamide and 2.4% in the case of conducting the reaction in tetrahydrofuran.
