Description
Изобретение касаетс способа получени нового соединени бис-(1-бензоил-2,4-диоксифенил-5 )-метана общей формулыThe invention concerns a process for the preparation of a novel compound, bis- (1-benzoyl-2,4-dioxyphenyl-5) -methane, of the general formula
ОНОНONON
которое может быть использовано в производстве полимерных материалов.which can be used in the production of polymeric materials.
-Предлагаемый способ получени бис-(1-бензоил-2 ,4-диоксифенил-5)-метана основан на взаимодействии 2,4-диоксибензофенона с водным раствором формальдегида при кип чении в спиртовом растворе в присутствии кислого катализатора, например сол ной кислоты, в течение 4 час.The proposed method for producing bis- (1-benzoyl-2, 4-dioxyphenyl-5) -methane is based on the interaction of 2,4-dioxybenzophenone with an aqueous solution of formaldehyde by boiling in an alcohol solution in the presence of an acidic catalyst, for example hydrochloric acid, in for 4 hours
Пример. В трехгорлую колбу емкостью 0,25 л, снабженную обратным холодильником, мешалкой, термометром « капельной воронкой , загружают 26,77 г (0,125 г-м) 2,4-диоксибензофенона , 125 мл этилового спирта, 35 мл концентрированной сол ной кислоты и 5,5 млExample. In a three-necked flask with a capacity of 0.25 l, equipped with a reflux condenser, a stirrer, and a dropping funnel thermometer, 26.77 g (0.125 gm) of 2,4-dioxybenzophenone, 125 ml of ethyl alcohol, 35 ml of concentrated hydrochloric acid and 5 , 5 ml
(0,062 г-м) 34%-ного водного раствора фор20(0,062 gm) 34% aqueous solution of form20
мальдегида (d4 1,097).Maldehyde (d4 1.097).
Реакционную массу нагревают до кипени , выдерживают при температуре кипени в течение 4 час, затем охлаждают до комнатной температуры и выливают в воду. Выпавший продукт отфильтровывают и промывают на фильтре водой до исчезновени хлор-иона. Продукт сушат при температуре 40-60°С. Получают 24,9 г бис-(1-бензоил-2,4-дноксифенил-5 )-метана, что составл ет выход 85,8%, счита на 2,4-Д оксибензофенон. Т. пл. - 201-203°С.The reaction mass is heated to boiling, maintained at boiling point for 4 hours, then cooled to room temperature and poured into water. The precipitated product is filtered and washed on the filter with water until the chlorine ion disappears. The product is dried at a temperature of 40-60 ° C. 24.9 g of bis- (1-benzoyl-2,4-dinoxyphenyl-5) -methane are obtained, which is 85.8% yield, calculated as 2,4-D hydroxybenzophenone. T. pl. - 201-203 ° C.
