Изобретение относится к применению углеродных нанотрубок с диаметром пор 7-11в качестве гетерогенного сокатализатора в процессе производства 4,4-диметил-1,3-диоксана (ДМД) путем конденсации трет-бутанола и формальдегида. При этом синтез ДМД проводят в присутствии фосфорной кислоты, взятой в качестве базового кислотного катализатора. Технический результат: увеличение селективности образования 4,4-диметил-1,3-диоксана. 1 з.п. ф-лы, 1 табл., 2 пр. |
