3-nitro-4-methylphenol prodn - by nitrating para-cresol carbonate, diluting with water and saponifying with ammonia

摘要

3-Nitro-4-methylphenol (I) is produced in high purity and high yields by reacting p-cresol carbonate with HNO3, pptg. the resulting 3-nitro-4-methylphenyl carbonate by diluting with H2O at 85-100 degrees C, and saponifying the prodt. with aq. NH4OH at 65-80 degrees C. (I) is an inter. for dyes and herbicides.
