Chemical properties Colorless or light yellow flammable liquid. It smells of phenol. Soluble in about 40 times water (water solubility of 2.5% at 40 ° C, 5.5% at 100 ° C). Soluble in caustic soda and common organic solvents. Use GB2760-1996 for permitted use of edible spices. Uses M-cresol, also known as m-cresol, is mainly used as a pesticide intermediate to produce insecticides such as mephos, fenthion, sofenocarb and pyrethroid alcohol partial m-phenoxybenzaldehyde. It is mainly used as an intermediate of pesticides, producing insecticides such as pyrimetrone, fenthion, sofenocarb, permethrin, and also an intermediate of color film, resin, plasticizer and spice. Uses M-cresol can be used as an analytical reagent, organic synthesis, fungicide, anti-mold agent, developer. The production method is mainly synthetic Chemicalbook method in foreign countries, and can also be separated from mixed cresol, a by-product of coking, oil shale distillation and city gas. The azeotrope method, urea method, benzene dissociation method, sulfonation hydrolysis method, phenol crystallization method, alkylation method and other methods can be used to separate the para-cresol.
