PURPOSE:To produce alkylphenols in high yield with single step reaction, by reacting a phenolic compound with an aldehyde and hydrogen in the presence of an alkali metal carbonate and/or bicarbonate and a hydrogenation catalyst. CONSTITUTION:An alkylphenol (e.g. 2,6-di-t-butyl-4-methylphenol) can be produced by reacting a phenolic compound with an aldehyde and hydrogen in the presence of an alkali metal carbonate (e.g. sodium carbonate, potassium carbonate, etc.) and/or an alkali metal bicarbonate (e.g. sodium bicarbonate) and a hydrogenation catalyst (especially preferably palladium-carbon catalyst or platinum-carbon catalyst). The compound is useful as an antioxidant, a raw material for chemicals, etc. |
