The structure and properties of the catalysts were characterized by BET, powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy analysis (FT-IR), NH3-TPD and Py-FTIR. When the molar ratio of amount of substance of α-pinene to oxalic acid is 1∶0.4, the mass ratio of CNMS-SO3H catalyst to turpentine oil is 7∶100, the temperature is 100 ℃ and the time is 8 h, the conversion of α-pinene is 100% and the yield of borneol is 49.89% and the amount of borneol is 4 times of that of isoborneol. The solid acid catalyst has good catalytic activity and stability. After 8 times of reuse, the conversion of α-pinene is over 99%. %U http://yyhx.ciac.jl.cn/EN/10.11944/j.issn.1000-0518.2020.12.200097
