Путем последовательной интеркаляции каолина диметилсульфоксидом и метанолом с после дующей обработкой раствором хлорида цетилтриметиламмония получены алюмосиликатные нанотрубки (АНТ) длиной 600–1000 нм и диаметром 15–25 нм. Впервые показано, что обработка АНТ смесью H2SO4–H2O2 приводит к удалению из них органических примесей и появлению каталитической активности в реакции изомеризации эпоксида α-пинена, продуктами которой являются камфоленовый (41,4 %) и изо-камфоленовый (22,7 %) альдегиды в циклогексане и транс-карвеол (до 56,0 %) в диметилсульфоксиде.

Aluminosilicate nanotubes (ANT) with a length of 600–1000 nm and a diameter of 15–25 nm were obtained by successive intercalation of kaolin with dimethyl sulfoxide and methanol followed by treatment with a cetyltrimethylammonium chloride solution. It is shown for the first time that the treatment of ANT with a mixture of H2SO4 –H2O2 leads to removing organic impurities from them and appearing catalytic activity in the α-pinene epoxide isomerization, the products of whicn are campholenic (41.4 %) and iso-campholenic (22.7 %) aldehydes in cyclohexane and trans-carveol (up to 56.0 %) in dimethyl sulfoxide.
