Carbon nanotubes with a pore diameter 7-11 Å as a heterogeneous cocatalyst. Therein synthesis of DMD is carried out in the presence of 5.0-5.5 wt.% of phosphoric acid, based on the weight of the reaction mixture taken as the basic acid catalyst.EFFECT: increasing the selectivity of the formation of 4,4-dimethyl-1,3-dioxane.1 cl, 1 tbl, 2 ex Изобретение относится к области основного органического и нефтехимического синтеза и может быть использовано в производстве 4,4-диметил-1,3-Диоксана путем конденсации изобутилена и формальдегида. Предложены углеродные нанотрубоки с диаметром порв качестве гетерогенного сокатализатора. При этом синтез ДМД проводят в присутствии в присутствии 5,0-5,5 мас.% фосфорной кислоты от массы реакционной смеси, взятой в качестве базового кислотного катализатора. Технический результат: увеличение селективности образования 4,4-диметил-1,3-диоксана. 1 табл., 2 пр.
