The invention, aiming at problems in current preparation of a propargite technical intermediate namely 2-(4-tert-butyl phenoxy) cyclohexanol, provides a preparation method of 2-(4-tert-butyl phenoxy) cyclohexanol. According to the preparation method, condensation with phenol is adopted at first, then alkylation is performed, and because of a steric hindrance effect, an isomer is hardly generated, and the content of the intermediate namely 2-(4-tert-butyl phenoxy) cyclohexanol is greatly improved. The 2-(4-tert-butyl phenoxy) cyclohexanol adopts phenol as a raw material subjected to condensation with epoxy cyclohexane at first, and then alkylation on benzene rings is performed, and because of the increase of the steric hindrance effect of a substituent namely cyclohexyl, the generation of ortho-alkylation and meta-alkylation isomers is avoided, thereby improving the content of the product.
