含三氟甲基的化合物应用在染料工业上,是比较新近的发展。三氟甲基常能提高染料的耐光坚牢度而可不减低其他方面的性质。含三氟甲基的染料现在应用较多的是偶氮染料及蒽醌染料,亦见于其他类别,但比较次要。氟和芳香族化合物作用,通常不是全成取代物,而是同时进行着加成作用与取代作用,因此生成的产物有饱和的环烃氟衍生物。有时由于碳链的破裂而生成脂肪族烃的衍生物。例如苯与氟在用氮稀释的情况下在气相中作用,生成物中有饱和的氟衍生物(由甲烷至戊烷),亦有氟代环己烷(例如
Trifluoromethyl compounds used in the dye industry, is a relatively recent development. Trifluoromethyl often enhances the fastness to light without reducing other properties. Trifluoromethyl-containing dyes are now more commonly used azo dyes and anthraquinone dyes, also found in other categories, but more importantly. Fluorine and aromatic compounds, usually not a complete replacement, but at the same time the addition and substitution, so the resulting product is a saturated cyclic hydrocarbon fluorine derivatives. Derivatives of aliphatic hydrocarbons sometimes result from the rupture of the carbon chain. For example, benzene and fluorine act in the gas phase when diluted with nitrogen and have saturated fluorine derivatives (from methane to pentane) and fluorocyclohexanes (for example,
