FIELD: chemistry.
SUBSTANCE: invention relates to an improved method of producing 2-[(dimethylamino)methyl]phenol used in the food industry and medicine, as well as lubrication and engine oil additives, corrosion inhibitors for different types of steel, stabilisers of motor car and rocket fuel, monomers, plastic and different types of rubbers. The method involves reacting phenol with N,N,N,N-tetramethylmethylenediamine. The reaction is carried out in the presence of a copper (I) chloride catalyst in molar ratio phenol: N,N,N,N-tetramethylmethylenediamine: CuCl=10:(10-11):(0.2-0.4) at atmospheric pressure, mainly at temperature of 50°C for 3.5-4.5 hours.
EFFECT: increased selectivity of the process and output of the desired product, reduced reaction temperature.
