| Abstract: | Musk DDHI was prepared by the cyclialkylation with 2,6 diisopropylphenol and isoprene catalyzed by heteropoly acid. The influences of types and amounts of catalysts, the proportion of the ingredients the time and temperature of the reaction on the experimental results were studied. The optimium reaction condition was as follows: catalyst C 1 which is a phosphotungstate heteropoly acid supported on activated carbon , 2,6 diisopropylphenol / isoprene=2.0(mol/mol), C 1 cat / isoprene=0.8～0.9(wt/wt), temperature 36 ℃～42 ℃,dropping time 2 h,heat preservation time 1 h,the yield based on isoprene was 83.7%. |
