Process for preparing nitric acid esters of 1,1,2,2-tetrahydro-perfluoro-alkanols

摘要

2-Perfluoroalkyl ethanols are obtained by reacting 2-perfluoro-alkyl ethyliodides with at least the two-fold molar amount of nitric acid of about 70 to 98 percent strength and hydrogenating the intermediates, which are the nitrates of the desired ethanols. The products are useful as starting materials for the production of hydrophobic and oleophobic textile finishing agents, e.g. the polymer acrylates and methacrylates of said 2-perfluoroalkyl-ethanols.
