ABSTRACT:
A method of producing 2,2'-methylenebis(4,6-dialkylphenols) residing in that 2,4-dialkylphenols interact with acetals in the presence of an acid catalyst at a temperature from 30.degree. C to 140.degree. C with the formation of a reaction mixture containing the desired product and with subsequent separation of the desired product from said mixture, the starting reagents being taken in amounts of 1 mole of 2,4-dialkylphenol per 1-10 moles of acetal.
The method is technologically simple and accomplished without the formation of waste water.
