查询词典 amount

When the amount of SO(superscript 2- subscript 4)/ZrO2 catalyst was 7% of the mass of β-pinene, the yield of product was 62.0%, and the mass ratio of borneol to isoborneol in the product was 13.6:48.7. When the amount of S2O(superscript 2- subscript 8)/ZrO2 catalyst was 7% of the mass of β-pinene, the yield of product was 66.7%, the mass ratio of borneol to isoborneol in the product was 11.5:49.5. Both two catalysts were poor for borneol selectivity.

在上述反应条件下，当催化剂SO(上标 2-下标 4)/ZrO2用量为7%时（以β-蒎烯质量计，下同），粗龙脑产率为62.0%，产品中正、异龙脑比为13.6：48.7；当催化剂S2O(上标 2-下标 8)/ZrO2用量为7%时，粗龙脑产率为66.7%，正、异龙脑比为11.5：49.5；这两种催化剂对正龙脑选择性比较差。
