Изобретение относитс к з овершойстабЁанию способа получени ацетиленди ка1збонЬ:Б ,ой «ислоты; примен юш,ей|С Б полимернои промышленности.This invention relates to an overstatement of a process for the preparation of acetylidene carbon: B, oi islota; Apply Yush to her | S B polymer industry.
Известный способ получени ацетилендикарбоновой кислоты электрохимическим окислением бутиндиола в растворе серной кислоты требует применени специального &л ёкт р о X и м.ич еокоГО обор удов а к и .The known method of producing acetylenedicarboxylic acid by the electrochemical oxidation of butynediol in a solution of sulfuric acid requires the use of a special & lterct X and m. Equipment that satisfies and.
С целью упрощени процесса, предлагаетс Ё качестве окислител примен ть перекись никел в :Вод1-ю-,гцело.чной среде, преимущественно при 30-50°С в течение 1 час. Выход целевого (продукта 65%.In order to simplify the process, it is proposed to use as Nickel peroxide as an oxidizing agent in: Water 1-th-, whole-cell medium, preferably at 30-50 ° C for 1 hour. The yield of the target (product 65%.
Пример. К раствору 25 г бутиндиола JB 20 мл воды, содержащей 25 г едкого кали, прибавл ют порци ми 160 г перекиси никел , перемешивают 1 час при 30-50°С, отфильтровывают перекись никел , промьюаЮт 30 мл воды, подкисл ют фильтрат серной, кислотой по (КОНГО, экстрагируют эфиром; сушат экстракт MgSO, растворитель отгон ют И получают 21,5 г (66%) ацетилендикарбоновой кислоты, т. пл. 189-192°CiExample. To a solution of 25 g of butyndiol JB, 20 ml of water containing 25 g of potassium hydroxide, 160 g of nickel peroxide are added in portions, stirred for 1 hour at 30–50 ° C, nickel peroxide is filtered off, washed with 30 ml of water, the filtrate is acidified with sulfuric acid, acid (CONGO, extracted with ether; the MgSO4 is dried, the solvent is distilled off, and 21.5 g (66%) of acetylenedicarboxylic acid are obtained, mp 189-192 ° Ci
Предмет и з о б р е т е .н и Subject and s o rt e.
Способ получепи ацетиленднкарбонОВОй кислоты окислением бутиндиола, отличающийс тем, что, с целью упрощени , процесса , в качестве окислител используют перекись никел и процесс ведут в воднощелочной среде с последующим выделение-М целевого продукта известными приемами. АЦЕТИЛЕНДИКАРБОНОВОЙ КИСЛОТЬThe method of obtaining acetylidenecarboxylic acid by the oxidation of butynediol, characterized in that, in order to simplify the process, nickel peroxide is used as an oxidizing agent and the process is carried out in an aqueous alkaline medium followed by isolation of the desired product by known techniques.
