Изобретение относится к технологии органической химии, а именно к способам очистки этилового синтетического технического спирта от примесей альдегидов и кетонов. Целью изобретения является возможно более полная очистка синтетического этилового спирта от примесей уксусного и кротонового альдегидов и ацетона. Это достигается обработкой этилового синтетического технического спирта с последующим кипячением и перегонкой реагентом, выбранным из ряда: резорцин, мочевина, гидроксиламин сернокислый, гидразингидрат, гидразин сернокислый, сульфит натрия, димедон, масло соевое, масло подсолнечное, едкий натр или едкое кали при определенном соотношении реагент - едкая щелочь. Очищенный этиловый синтетический технический спирт пригоден для использования в аэрозольных препаратах.The invention relates to the technology of organic chemistry, and in particular to methods of purification of ethyl synthetic industrial alcohol from impurities of aldehydes and ketones. The aim of the invention is the most complete purification of synthetic ethyl alcohol from impurities of acetic and crotonaldehydes and acetone. This is achieved by processing ethyl synthetic industrial alcohol, followed by boiling and distillation with a reagent selected from the range: resorcinol, urea, hydroxylamine sulfate, hydrazine hydrate, hydrazine sulfate, sodium sulfite, dimedon, soybean oil, sunflower oil, caustic soda or potassium hydroxide in a certain ratio of reagent - caustic alkali. Purified ethyl synthetic technical alcohol is suitable for use in aerosol preparations.
