Beschreibung
Zusammenfassung:	EFFECT: organic synthesis.SUBSTANCE: invention relates to the use of carbon nanotubes with a pore diameter of 7-11as a heterogeneous co-catalyst in the production of 4,4-dimethyl-1,3-dioxane (DMD) by condensation of tert-butanol and formaldehyde. In this case, the synthesis of DMD is carried out in the presence of phosphoric acid, taken as a base acid catalyst.EFFECT: increase in the selectivity of the formation of 4,4-dimethyl-1,3-dioxane.1 cl, 1 tbl, 2 ex 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.
