light yellow to white oily liquid. The solid is a leaf-like crystal. Melting point 15 °c. Boiling point 194.3 °c. The relative density was 1. 041. Refractive index 1.5780. Flash Point 63. Soluble in ethanol, soluble in ether, insoluble in water. Can be volatilized with water vapor. She has extra odor.
after diazotization, o-toluidine is esterified with ethyl xanthate potassium to obtain O-toluate ethyl ester, which is made into O-toluenethiol potassium salt and then hydrolyzed by sulfuric acid.
