含氧汽油混合燃料蒸气压对环境影响及快速检测方法研究

Influence of Vapor Pressure of Oxygenated Gasoline Mixture on Environment and Its Rapid Measurement Method

蒸气压是检验汽油品质的重要物理性质之一,其大小对汽油的存放、运输和使用有重要影响。过高蒸气压的石油产品,由于挥发性较高容易对生态环境造成污染。随着大家保护环境意识日益增强,因此对汽油蒸气压的测定也尤为重要。本实验采用微量法快速测定汽油饱和蒸气压,与传统测定方法雷德法相比,具有测定速度快、取样量少、精密度好的特点。

The vapor pressure is one of the important physical properties to test the quality of gasoline,and its size has an important influence on the storage,transportation and use of gasoline.Petroleum products with high vapor pressure tend to pollute the ecological environment due to their high volatility.With the increasing awareness of environmental protection,the determination of gasoline vapor pressure is particularly important.In this experiment,the micro-method is used to determine the saturated vapor pressure of gasoline rapidly.Compared with the traditional method,the method has the characteristics of fast determination speed,less sampling volume and good precision.
