Description
Известен способ получени 1,1,3,3-тетрациаппропана , заключающийс во взаимодействии динитрила малоновой кислоты с формалином в присугствнн пинеридииа.A method of producing 1,1,3,3-tetracyapropane is known, which consists in the interaction of malonic dinitrile with formalin in the presence of pineridium.
Дл ускорени процесса получени 1,1,3,3тетрациаипропана предлагаетс в качестве катализатора использовать |3-аланин.In order to accelerate the process of obtaining 1,1,3,3 tetracionic propane, it is proposed to use | 3-alanine as a catalyst.
Пример. К раствору 150 г динитрила малоновой кислоты в 750 мл этанола при размешивании прибавл ют 86 мл 36,5а/о-иого формалина и 0,5 г р-аланина. Температура реакционной смеси ноднимаетс за полчаса па 10-12°С. Одповременно с подъемом температуры начинаетс выделение крнсталлов тетрацианпропана; реакци заканчиваетс за 4 час, нричем темнература реакционной смеСИ ностепеппо снижаетс до комнатной. Осадок тетрацианпропана отфильтровывают, промывают водой, тщательно отжимают и сушат в вакууме прп 100°С до посто нного веса.Example. To a solution of 150 g of malonic acid dinitrile in 750 ml of ethanol, while stirring, 86 ml of 36.5a / o formalin and 0.5 g of p-alanine are added. The temperature of the reaction mixture rises within half an hour at 10-12 ° C. Along with the rise in temperature, the release of tetracyanpropane crystals begins; the reaction is completed in 4 hours, and the temperature of the reaction mixture is reduced to room temperature. The precipitate of tetracyanpropane is filtered off, washed with water, squeezed thoroughly and dried in a vacuum of 100 ° C to constant weight.
