Пример 2. В стекл нную банку , снабжекпую мешалкой, загружают 50 вее. ч. еол покпелого диметнланилина , 165 вее. ч. ЗОУо-ного раствора сол ной кислоты, 62,5 вес. ч. спирта и катализатор, состо пхий из 0,12 вес. ч. хлористого марганца и 0,15 вес. ч. хлористой меди.Example 2. A glass jar supplied with a stirrer was charged 50 ve. including eol pokpely dimetnlanilina, 165 BEE. part of the hydrochloric acid ZOUo-solution, 62.5 wt. including alcohol and catalyst consisting of 0.12 wt. including manganese chloride and 0.15 weight. including copper chloride.
Затем при работающей мешалке в течение трех часов подают смесь из 37,5 вес. ч. спирта, 65 вес. ч. ,№ 95176 гва кола и раствора 16 вес. ч. уротропина в 24 вес. ч. воды и выдерживают в течение одного часа. Конденсацию ведут при температуре 40-45°. Предмет и Способ получени ароматическид оксиальдегидов из фенолов и их пройзв5дных конденсацией с формальдегидом и нитрозосоединени ми в кислЪй среде без воестанойлени питрозосоединени .. формал-ьдегидом или металлом, о тПо окончании реакции в полученную смесь добавл ют 80 вес. ч. воды, перемешивают в течение одного часа и образовавшийс вани извлекают известным способом . обретени личаюгцийс тем, что дл увеличени выходов продукта реакцию конденсации провод т в присутствии катализаторов солей двухвалентных металлов первой- седьмой группы периодической системы или смеси этих солей.Then, with the mixer running, a mixture of 37.5 wt. Is fed for three hours. h. alcohol, 65 wt. h., No. 95176 gva cola and solution 16 wt. including hexamine in 24 wt. including water and incubated for one hour. Condensation is carried out at a temperature of 40-45 °. Subject and Method for the preparation of aromatic oxaldehydes from phenols and their proisal by condensation with formaldehyde and nitroso compounds in an acidic environment without decomposition of the pitroso compound. Formaldehyde or metal, 80% of the mixture is added to the resulting mixture. water, stirred for one hour and the resulting vanium is removed in a known manner. gaining lesions with the fact that in order to increase the product yields, the condensation reaction is carried out in the presence of catalysts of divalent metal salts of the first and seventh groups of the periodic system or a mixture of these salts.
