Reaction Conditions:

with hydrogen;platinum at 160; for 4 h;Reagent/catalyst;Temperature;

Steps:

1

Add 2.6 g of platinum catalyst to a 1 L reactorAnd 260 g of 2,6-di-tert-butyl-4(dimethylaminomethyl)phenol,Then hydrogen is introduced, and the hydrogenolysis process maintains the system temperature at 160 ° C.The molar ratio of hydrogen to 2,6-di-tert-butyl-4(dimethylaminomethyl)phenol is 2:1,Hydrogenation reaction for 4 hours, hot filtration to remove the catalyst,The crystal was cooled to give 215.16 g of 2,6-di-tert-butyl-p-methylphenol.
