Solvent Red 26, also known as C.I. 26120, is a purplish red synthetic azo dye. It is soluble in oils and insoluble in water. Its main use is as a standard fuel dye in the US mandated by the US IRS to distinguish low-taxed or tax exempt heating oil from automotive diesel fuel, and by the EPA to mark fuels with higher sulfur content; it is however increasingly replaced with Solvent Red 164, a similar dye with longer alkyl chains, which is better soluble in hydrocarbons. 〔http://www.chevron.com/products/prodserv/fuels/bulletin/diesel/L2_3_9_rf.htm 〕 The concentration required by IRS is a spectral equivalent of 3.9 pounds per 1000 barrels, or 11.13 mg/l, of Solvent Red 26 in solid form; the concentrations required by EPA are roughly 5 times lower. ==See also ==
