Paragraph 0041; 0042, (2018/07/30)
The invention discloses a preparation method of 2,6-ditertbutyl p-alkylphenol. The preparation method comprises the following steps of: 1) adding aqueous or alcohol solution of aldehyde and dimethylamine and alcohol solution of 2,6-ditertbutylphenol into a reaction kettle, and reacting to obtain 2,6-ditertbutyl-4-(dimethylaminoalkyl)phenol, wherein the aldehyde is fatty aldehyde with 1-5 carbon atoms; 2) carrying out catalytic hydrogenolysis on 2,6-ditertbutyl-4-(dimethylaminoalkyl)phenol prepared by the step 1) in the reaction kettle to obtain 2,6-ditertbutyl p-alkylphenol. The preparation method disclosed by the invention has the advantages that the raw materials are low in cost and easy in obtaining, no corrosive waste water is caused, the reaction yield is high and the purity and the yield of a product can be up to 98% or more.
