Ethylene fluorhydrin - Nature
Open Data Verified Data
a colorless liquid with an alcohol odor. Stable nature, distillation does not decompose, and water and many organic solvents miscible. Boiling point 103.5 °c. Melting Point -26. 45 °c. The relative density (d20) was 1. 1040. Refractive index 3647. The chemical properties are similar to those of ordinary alcohols, and the corresponding aldehydes and acids can be obtained by oxidation. An alkoxide is formed by reaction with an alkali metal or an alkaline earth metal, thereby forming an ether.
