摘要： A method for the production of 2,4,6-tri(3,5-ditertiary butyl-4-hydroxybenzyl)mesitylene which resides in treating a mesitylene solution in chloroalkane simultaneously with sulfuric acid used as a catalyst and a solution of 2,6-ditertiary butyl-4-methoxymethylphenol or bis-3,5-ditertiary butyl-4-hydroxybenzyl ether in chloroalkane at a temperature of -20.degree. to +20.degree. C. This results in a reaction mixture consisting of an acid phase and an organic phase including the target product. The phases are separated. The organic phase is subjected to neutralization by the treatment thereof with gaseous ammonia used as an alkaline agent. The precipitate of ammonium sulfate is separated and chloroalkane is removed from the remaining solution.The proposed method makes it possible to obtain the target product with a yield of 88 to 90% and a melting temperature of 239.degree. to 239.5.degree. C.The method prevents the formation of effluents, and the amount of phenol wastes is considerably reduced.
