description FIELD: chemistry.SUBSTANCE: process of condensation is carried out with aldehydes glycol of various buildings in supercritical conditions at a temperature of 390°C and a pressure of 300 atmospheres in the presence of the following components, wt %: ethylene glycol 87.4; butyric (isobutyric) aldehyde 12.6; or ethylene glycol 84 benzaldehyde 16.EFFECT: increase in output as well as quality of the end product.1 dwg,1 tbl, 1 ex Изобретение относится к новому способу получению циклических ацеталей, которые находят применение в качестве растворителей, компонентов лакокрасочных материалов и субстратов в тонком органическом синтезе. Способ заключается в том, что проводят процесс конденсации этиленгликоля с альдегидами различного строения в сверхкритических условиях при температуре 390°C и давлении 300 атм в присутствии следующих компонентов, мас.%: этиленгликоль 87,4; масляный (изомасляный) альдегид 12,6; или этиленгликоль 84 бензальдегид 16. Технический результат - увеличение выхода целевого продукта при повышении его качества. 1 ил., 1 табл., 1 пр.
