含氧化合物

The essential oil was prepared from the peel by solution extraction, and separated into fractions of hydrocarbon and oxygenated compounds through a silicagel column. As the oxygenated fraction had the characteristic aroma of the peel oil, odor quality of the fraction was estimated on the basis of a odor unit value. Twenty five compounds such as geranial, neral, linalool and aliphatic aldehydes were selected as the components contributed to the aroma of the peel oil.

用溶剂萃取法提取白柠檬果皮的精油，并用硅胶柱将精油分成碳氢化合物和含氧化合物两大部分，由于含氧化合物部分具有果皮油的特征香气，利用各成分的香气值对该部分进行了评价，明确了香叶醛、橙花醛、沉香醇以及一些脂肪族醛等25种成分对白柠檬果皮油香气起着重要作用。

Methane, oxygen and H_2O molecules are activated, ionized and dissociated into active particles such as CH_3~+, O~-, H_2O~+, CH_3, CH_2, CH, H,OH and O, by nonelastic collision with high energy electrons. The particles react with each other in the reactor to synthesize chemically products including gaseous oxy-hydrocarbons.We study the rule of reaction by changing electrical parameter, gas flow etc. Study the conversion of methane, selectivity of gaseous hydrocarbons and yield of methanol under different reaction condition.
