| description | The invention relates to the technical field of fine chemical synthesis, in particular to a Cu/HZSM-5 molecular sieve, preparation thereof and application of the Cu/HZSM-5 molecular sieve in raspberry ketone synthesis. The preparation method comprises the following steps: dissolving a copper salt, uniformly mixing the dissolved copper salt with an HZSM-5 molecular sieve, carrying out ammonia distillation treatment, and carrying out post-treatment to obtain a CuO/HZSM-5 molecular sieve; and then carrying out hydrogenation reduction treatment on the CuO/HZSM-5 molecular sieve to obtain the Cu/HZSM-5 molecular sieve. The Cu/HZSM-5 molecular sieve prepared by the method is used as a catalyst to catalyze H2 and 4-(4-hydroxyphenyl)-3-butene-2-ketone to generate raspberry ketone, the catalytic efficiency is high, the conversion rate of the 4-(4-hydroxyphenyl)-3-butene-2-ketone can reach 100%, the selectivity of the raspberry ketone can reach 99.8% at most, and the Cu/HZSM-5 molecular sieve has the advantages of low |
