You will convert the carvone to its semicarbazone for use in a polarimetric analysis.
为了作旋光度分析，你将会把香芹酮转变为缩胺基脲。
You will obtain infrared spectra of the carvone and limonene fractions and interpret the results.
你将得到香芹酮和柠檬烯馏份的红外光谱图。并且要解析其结果。
Which features in the IR spectrum can be assigned to limonene? To carvone? Identify as many functional groups as you can in each sample.
在红外光谱图中有哪些特征可以归属于是柠檬烯的？哪些可以归属于香芹酮？尽可能确认出在你的样品中出现的官能团。
When carvone begins to distill, the condensation can be seen inside the thermometer adapter, thus the progress of carvone distillation can be readily monitored.
当香芹酮开始蒸馏时，在温度计转接器内可看到有冷凝，因此能够容易地监察香芹酮的蒸馏过程。
This may create a problem because peppermint, with its menthol and derivatives, is an effective digestive aid whereas spearmint, which contains mainly carvone, is not.
会造成这一个问题是因为薄荷与其衍生物，是一种有效的消化援助，而留兰香，其中包含主要香芹酮，并没有这种功效。
Using the refractive index data determine the approximate composition of your oil, your carvone fraction and your limonene fraction with respect to limonene and carvone.
利用折光率的数据确定你的油中，你的香芹酮馏份和与柠檬烯和香芹酮有关的柠檬烯组份的大概成份。
The compounds are obtained by using carvone as an initial raw material through chlorination reaction, condensation reaction, sodium borohydride reduction and Huang Min-lon reduction reaction.
