Description
Изобретение относитс к способам получени р-фталоилакриловой кислоты (2-карбоксиметилениндандиона-1 ,3), который, с одной стороны , как 2-илиденпроизводное индандиоиа1 ,3 может быть использован дл синтеза много дерных гетероциклических систем; с другой - как производное акриловой кислоты, может найти применение в реакци х полимеризации .The invention relates to methods for producing p-phthalo-acrylic acid (2-carboxymethylenedi-dian-1, 3), which, on the one hand, as a 2-ylidene derivative of indandio-ia, 3, can be used for the synthesis of multi-nucleic heterocyclic systems; on the other hand, as a derivative of acrylic acid, it can be used in polymerization reactions.
Цель изобретени - разработка способаThe purpose of the invention is to develop a method
получени не известноГ в литературе р-фталоилакриловой кислоты (2-карбоксиметилениндандиопа-1 ,3), что достигаетс путем гидролиза 2-(а-окс11-р,р,р-трпхлорэтил)-индандиона-1 ,3 (I) с водным раствором карбоната кали и последующим отщеплением молекулы воды от полученной калиевой соли ипдандионил-1 ,3-гликолевой кислоты (П) концентрированной серной кислотой в растворе уксусной кислотыp-phthaloyl acrylic acid (2-carboxymethylenindian diopa-1, 3) is not known in the literature, which is achieved by hydrolysis of 2- (a-ox11-p, p, p-trphloroethyl) -indandion-1, 3 (I) with an aqueous solution potassium carbonate and subsequent removal of a water molecule from the potassium salt obtained, ipdandionyl-1, 3-glycolic acid (P) with concentrated sulfuric acid in an acetic acid solution

Пример. Перемешивают 5 г 2-(а-оксиР ,р,р-трихлорэтил)-индандиона-1,3 (I) и 15 г карбоната кали в 88 мл водного раствора диоксана (10 : 1) до нолного растворени . Реакционную смесь оставл ют при комнатной температуре на 3 час. Выпадают желтые кристаллы калиевой соли индандионил-1,3-гликолевой кислоты. Выход 3 г (68,3%) вещества II (из воды).Example. 5 g of 2- (a-hydroxyP, p, p-trichloroethyl) -indandion-1,3 (I) and 15 g of potassium carbonate in 88 ml of an aqueous solution of dioxane (10: 1) are stirred to dissolve. The reaction mixture was left at room temperature for 3 hours. Yellow crystals of the potassium salt of indandionyl-1,3-glycolic acid fall out. Yield 3 g (68.3%) of substance II (from water).
1 г калиевой соли индандионил-1,3-гликолевой кислоты (И) раствор ют в 15 мл смеси уксусной кислоты и концентрированной серной кислоты (2:1). Перемешивают 30 мин,1 g of the potassium salt of indandionyl-1,3-glycolic acid (I) is dissolved in 15 ml of a mixture of acetic acid and concentrated sulfuric acid (2: 1). Stirred for 30 minutes
и выливают в 20 мл воды. Осадок перекристаллизовывают из уксусной кислоты-и получают 0,45 г (57,5%) оранжевых кристаллов р-фталоилакриловой кислоты (III); т. нл. 215-216°С (разложение). Q Предмет изобретени Способ получени р-фталоилакриловой кислоты , отличающийс тем, что 2-{а-окси-р,р,|3трихлорэтил )-индандион-1,3 подвергают пос- 5 4 ледовательной обработке карбонатом кали в водном растворе диоксана и концентрнрованной серной кислотой в растворе уксусной кислоты с последующим выделением целевого продукта известными приемами.and poured into 20 ml of water. The precipitate is recrystallized from acetic acid, and 0.45 g (57.5%) of orange crystals of p-phthalo-acrylic acid (III) are obtained; so nl 215-216 ° C (decomposition). Q Subject of the invention. A method for producing p-phthaloyl acrylic acid, characterized in that 2- {a-hydroxy-p, p, | 3-trichloroethyl) -indandion-1,3 is subjected to post-treatment using potassium carbonate in an aqueous solution of dioxane and concentrated sulfuric acid. acid in a solution of acetic acid, followed by separation of the target product by known techniques.
