제올라이트 Y촉매에서의 페놀의 t-부틸화 반응
T-butylation of Phenol over Zeolite Y Catalyst
Alkylation of phenol with t-butanol on zeolite Y in liquid phase batch reactor was studied. The main products were 2,4-di-t-butylphenol, o-t-butylphenol, p-t-butylphenol, last of these was wanted product. In order to enhance the selectivity of p-t-butylphenol, optimum conditions were recommended 600℃ calcination temperature, 140℃ reaction temperature, 0.5 molar ratio of reactants over zeolite Y. P-t-butylphenol was formed with 87% isomer selectivity at optimum conditions after reaction 4 hrs.
