Abstract
1-Indanone was obtained from 3-phenyl-propanoic acid in 92.3% yield by intramolecular Friedel-Crafts acylation under catalysis of polyphosphoric acid(PPA).Its thermostability was investigated using differential scanning calorimetry and thermogravimetry.Results showed that in nitrogen atmosphere with a heating rate of 10 K.min-1,1-indanone could produce an intense thermolysis at 82.4℃.At 168℃ 99.8% of 1-indanone decomposed.
