Abstract A process for preparing alkylphenol includes such steps as reaction of C8-C16 olefin with phenol under the action of cationic exchange resin catalyst, removing catalyst, adding calcium oxide (0.1-5 wt.%), optional reaction at 50-150 deg.C for 10-120 min, removing dregs and separating out the olefin and phenol which did not take part in reaction. The resultant alkylphenol features light colour (ASTM 1500 chromaticity is less than or equal to 1), and high chromaticity stability.
