Description

Пример 2. К смеси 9,66 ч. 3 - нитрофтагювого ангидрида и 2,25 ч, 1,2,4 трихлорбенэола, негретой до 230° С, добавл ют 0,3 ч. jffiipHTa натри , выдерживают 50 мин при 230-236° С, наблюда  выделение окиси азота, охлаждают, раствор ют реакцисншую смесь   100ч. 5%-ного водного раствора едкого натра, разбавл ют 100ч. воды и экстрапфуют эфиром. Водаую фазу подкисл ют небольшим избытком концентрированной сол ной кислоты и продолжают зкстракфю. Экстракт вытривают в вакууме и получают в жое масло, которое кртсталлизуето  при сто нии. Получают дифеншювый 3 1, тетрак бонов( кислоты , Т.Ш1. 148-162° С, который раствор ют в 25 мл кип щего уксусного ангидрида, выпаривают досуха, кристалпи скнй остаток промывают уксусной кислот( и получают 2,2,3,3 .- тетракарбоксидиангид1Н1Д дифенилового желтого цвета с выходом ,1%.Example 2. To a mixture of 9.66 parts of 3 - nitroftaic anhydride and 2.25 hours, 1,2.4 of trichlorobeneol, unheated to 230 ° C, add 0.3 parts of sodium jffiipHTa, incubated for 50 minutes at 230-236 ° C, observed the release of nitric oxide, cooled, dissolving the reaction mixture 100 h. 5% aqueous solution of caustic soda, diluted 100h. water and extracted with ether. The water phase is acidified with a slight excess of concentrated hydrochloric acid and continued to crystallize. The extract is wiped off in vacuo and obtained in joj oil, which crystallizes upon standing. Blend 3 1, tetra booms (acids, T.Sh1. 148-162 ° C) are obtained, which is dissolved in 25 ml of boiling acetic anhydride, evaporated to dryness, and the crystalline residue is washed with acetic acids (and 2.2.3.3 .- tetracarboxydianide1H1D diphenyl yellow color with a yield of 1%.

Полученное вешество (45% от веса всей смеси) добавл ют к эпсжс джй уыкак, Полуниной из диглицидилсизого Сюсфенош - 1, в нагреваю1 до 160° С. Полученна  смола твердеет до отсутстви  отлипа.The obtained material (45% of the weight of the whole mixture) is added to the mixture of jy uykak, Polunina from the diglycidyl systine syusphenosh-1, in heating 1 to 160 ° C.

Можно проводить ксшденсацию в дафениловом эфире и трнхлорбензоле в присутствии 0,05-0,2 ч. нитрита кали , рубиди  и цези  при 2 -245°С.It can be carried out in daphenyl ether and trichlorobenzene in the presence of 0.05-0.2 parts of potassium nitrite, rubidium and cesium at 2 -245 ° C.

Выход целевого продукта 28,5-50,7%. Максимальный выход достигнут при применении 0,1 ч. нитрита рубиди  и проведении реакции при в течение 30 мин в трихлорбензоле.The yield of the target product 28,5-50,7%. The maximum yield was achieved by using 0.1 parts of rubidi nitrite and carrying out the reaction for 30 minutes in trichlorobenzene.
