Trihydric alcohols (i.e. Triols) are organic compounds containing three hydroxyl groups. The simplest trihydric alcohol is 1,2,3-propane-triol, CH2(OH)CH(OH)CH2(OH), which is also known as glycerol (from the Greek glykys meaning sweet) or glycerin. Glycerol is commercially produced by the hydrolysis of fats.
Glycerol is a by-product in the soap industry and is recovered by suitable means.
