NOVELTY - Preparing 2-bromo-4-methylphenol, comprises: e.g. (a) selecting a 1000 l reaction vessel, adding 390-410 kg of chloroform and 350-370 kg of cresol to the reaction vessel and then stirring, and introducing frozen brine into the stirred mixture at a temperature of 8-12 degrees C; (b) adding 45-55 kg of iron powder and a bromine solution to the mixture at 10-20 degrees C; (c) reacting the mixture under the presence of hydrogen bromide gas to obtain hydrobromic acid; and (d) dropwisely adding hydrobromic acid to 500-520 kg of bromine for 5.5-6.5 hours, and heating the mixture at 45-55 degrees C for 5.5-6.5 hours.    USE - The method is useful for preparing 2-bromo-4-methylphenol (claimed).    ADVANTAGE - The method is capable of reliably, conveniently and simply preparing the 2-bromo-4-methylphenol with high purity and without environmental pollution. The raw material of the 2-bromo-4-methylphenol is easy to obtain and is cost-effective.    DETAILED DESCRIPTION - Preparing 2-bromo-4-methylphenol, comprises: (a) selecting a 1000 l reaction vessel, adding 390-410 kg of chloroform and 350-370 kg of cresol to the reaction vessel and then stirring, and introducing frozen brine into the stirred mixture at a temperature of 8-12 degrees C; (b) adding 45-55 kg of iron powder and a bromine solution to the mixture at 10-20 degrees C; (c) reacting the mixture under the presence of hydrogen bromide gas to obtain hydrobromic acid; (d) dropwisely adding hydrobromic acid to 500-520 kg of bromine for 5.5-6.5 hours, and heating the mixture at 45-55 degrees C for 5.5-6.5 hours to obtain a reaction product; (e) centrifugating the reaction product to separate an internal iron mud, and filtering the product in a 1500 l steam distillation kettle; (f) washing the product with 10% sodium bicarbonate solution and anhydrous sodium sulfate and then filtering; and (g) heating the filtered product and then performing vacuum distillation to distill chloroform, collecting distillate of 2-bromo-4-methylphenol, and packaging the 2-bromo-4-methylphenol and then storing.
