Zusammenfassung:FIELD: chemistry.SUBSTANCE: invention relates to basic organic and petrochemical synthesis, namely to use of porous polyarylenephthalide as a heterogeneous cocatalyst in amount of 3.5-5.0 wt. % of the reaction mass during formation of 4,4-dimethyl-1,3-dioxane by condensation oftert-butanol and formaldehyde.EFFECT: increased selectivity of 4,4-dimethyl-1,3-dioxane formation.1 cl, 1 tbl, 2 ex Изобретение относится к области основного органического и нефтехимического синтеза, а именно к применению пористого полиариленфталида в качестве гетерогенного сокатализатора в количестве 3,5-5,0 мас.% от реакционной массы при образовании 4,4-диметил-1,3-диоксана путем конденсациитрет-бутанола и формальдегида. Технический результат: увеличение селективности образования 4,4-диметил-1,3-диоксана. 1 з.п. ф-лы, 1 табл., 2 пр.
