Abstract: Isolongifolane ketone Schiff base was synthesized with isolongifolane ketone and hydrazine as raw materials. The effects of different conditions on the reaction were studied by single factor and orthogonal experiments with the yield of the isolongifolane ketone Schiff base as the investigation index. The results showed that the optimized technological parameters were the catalyst dosage 0.6% (use the volume of all the material as the reference), ethanol as the solvent, reaction time 24 h, reaction temperature 78 ℃ and n(isolongifolane ketone):n(hydrazine) 1:5. Under these conditions, the yield of the product was 87.84%, and its chemical structure was analyzed by GC-MS,FT-IR and 1H NMR spectra. They proved that the isolongifolane ketone Schiff base was synthesized.

Key words: isolongifolane ketone, hydrazine, Schiff base, turpentine
