Supported molecular sieve catalyst for synthesis of 4-methyl-2, 6-ditert butyl phenol and application thereof

The invention discloses a supported molecular sieve catalyst for synthesis of 4-methyl-2, 6-ditert butyl phenol and application thereof, and the supported molecular sieve catalyst is prepared by usinga molecular sieve modified by any one of sodium fluoride, potassium fluoride and ammonium fluoride as a carrier to support active components A and B. The molecular sieve is H beta molecular sieve, H-mordenite, HY molecular sieve, USY molecular sieve, REY molecular sieve or SAPO-5 molecular sieve, the active component A is Co, Cu, Ni or Fe, the active component B is Pt, Au, Ag, Pd, Ru and Rh, theloading of the active component A is 4%-10%, and the loading of the active component B is 0.1%-1% calculated on the basis of the carrier. The supported molecular sieve catalyst is used in production of the 4-methyl-2, 6-ditert butyl phenol from p-methylphenol and isobutene or tert-butanol, and has the advantages of low catalyst cost, high raw material conversion rate, high product selectivity, catalyst service life, simple
