Abstract
1. Способ получения гексафторизопропанола, включающий восстановление гексафторацетона восстановителем, отличающийся тем, что восстановление осуществляют с использованием в качестве восстановителя гидразина с последующим введением пероксида водорода.2. Способ по п.1, отличающийся тем, что мольное соотношение гексафторацетона и гидразина поддерживают равным 1:1,1-1,5.3. Способ по п.1, отличающийся тем, что пероксида водорода используют в виде 36-50%-ного раствора пероксида водорода.1. A method of producing hexafluoroisopropanol, comprising reducing hexafluoroacetone with a reducing agent, characterized in that the reduction is carried out using hydrazine as a reducing agent, followed by the introduction of hydrogen peroxide. 2. The method according to claim 1, characterized in that the molar ratio of hexafluoroacetone and hydrazine is maintained equal to 1: 1.1-1.5.3. The method according to claim 1, characterized in that the hydrogen peroxide is used in the form of a 36-50% solution of hydrogen peroxide.
