2-Fluoroethanol is the organic compound with the formula CH 2 FCH 2 OH. This colorless liquid is one of the simplest stable fluorinated alcohols. It was once used as a pesticide. The related difluoro- and trifluoroethanols are far less dangerous. [4]
Phenethyl alcohol is prepared commercially via two routes. Most common is the Friedel-Crafts reaction between benzene and ethylene oxide in the presence of aluminium trichloride. C 6 H 6 + CH 2 CH 2 O + AlCl 3 → C 6 H 5 CH 2 CH 2 OAlCl 2 + HCl. The reaction affords the aluminium alkoxide that is subsequently hydrolyzed to the desired product.
Most primary and secondary perfluoroalcohols are unstable, for example trifluoromethanol eliminates hydrogen fluoride, forming carbonyl fluoride. [2] This reaction is reversible. [3] CF 3 OH → COF 2 + HF. Stable perfluorinated alcohols include nonafluoro-tert-butyl alcohol ((CF 3) 3 COH) and pentafluorophenol (C 6 F 5 OH).

Phenoxyethanol has germicidal and germistatic properties. [6] It is often used together with quaternary ammonium compounds.. Phenoxyethanol is used as a perfume fixative; an insect repellent; an antiseptic; [7] a solvent for cellulose acetate, dyes, inks, and resins; a preservative for pharmaceuticals, cosmetics and lubricants; [8] an anesthetic in fish aquaculture; [9] [10] and in organic ...
Hexafluoro-2-propanol has very low acute toxicity, hence its use as a precursor to anesthetics. Although it has low acute toxicity, it is a strong irritant to skin and eyes. [2] Animal experiments show possible adverse effects on fertility, [10] placing HFIP as a reproductive toxicity category 2 material. [11]
2,2,2-Trifluoroethanol is the organic compound with the formula CF 3 CH 2 OH. Also known as TFE or trifluoroethyl alcohol, this colourless, water-miscible liquid has a smell reminiscent of ethanol. Due to the electronegativity of the trifluoromethyl group, this alcohol exhibits a stronger acidic character compared to ethanol.
