Abstract
A process for the preparation of 3, 5-di-tert-butyl-4-hydroxy-methoxybenzyl alcohol by reacting 2, 6-di-tert-butylphenol with formaldehyde and methanol in the presence of a basic catalyst at elevated temperature characterized in that used as a catalyst is N, N, N(, N(-tetra-methyl-di- aminomethane compound and the process is carried out at a temperature in the range of 60-100]C with the molar ratio of 2, 6-di-tert-butylphenol to formaldehyde to methanol to catalyst as of 1.0:1.0-1.5:10-15:0.01-0.50.
