The present invention relates to a selective preparation method of di-styrenated phenol. In the selective preparation method of the present invention, a phenol compound represented by chemical formula 2 and a styrene monomer are reacted in the presence of a solid acid catalyst with sulfate ions loaded on a mixed metal oxide, wherein the solid acid catalyst is prepared by impregnating a mixed metal oxide in an aqueous sulfuric acid solution, wherein the mixed metal oxide is a mixture of titanium dioxide and zirconium oxide and represented by chemical formula 1. In the chemical formulas 1 and 2, R_1 and R_2 are each independently selected from hydrogen, an alkyl group having 1-20 carbon atoms, an alkoxy group having 1-20 carbon atoms, a cycloalkyl group having 3-30 carbon atoms, and an aryl group having 6-30 carbon atoms. 본 발명은 혼합금속산화물을 황산수용액에 함침하여 제조된 황산이온을 담지한 혼합금속산화물 고체 산촉매 하에서, 하기 화학식 2로 표시되는 페놀 화합물과 스티렌 단량체를 반응시킨 것이고, 상기 혼합금속산화물은 이산화티타늄과 산화지르코늄의 혼합물인 하기 화학식 1로 표시되는 디-스티렌네이티드 페놀의 선택적 제조방법에 관한 것이다. [화학식 1][화학식 2](상기 화학식 1 내지 2에서, R및 R는 각각 독립적으로 수소, C-C의 알킬기, C-C의 알콕시기, C-C의 시클로알킬기 및 C-C의 아릴기에서 선택된다.)
