摘要
常压蒸馏制备二元恒沸混合物溴丙烷/正己烷,并作恒沸物与标样的气相色谱分析.拟合标样两组分体积比与峰面积比的函数关系,进而计算出恒沸物两组分的体积比为89.9∶10.1.进行外观、物理稳定性、相对密度、黏度、残留量、挥发速度、pH值、绝缘电阻值、含水质量分数、表面张力、污垢洗净率等性能测定,结果显示各项性能均达到了带电清洗剂的要求,可以作为新型带电清洗剂推广.
The azeotropes bromopropane/n-hexane was prepared by atmospheric distillation, and the azeotrope and samples were analyzed by gas chromatography. The functional relationship between the volume ratio and peak area ratio of the samples was fitted. As a result, the volume ratio of two components of azeotrope was calculated as 89.9： 10. 1. All kinds of the cleaning performance of the azeotrope cleaning agent such as appearance, physical stability, relative density, viscosity, violating speed, pH value, insulation resistance, water content, surface tention and wash-ratio were measured. The results show that all the performances meet the requirements of the on-line cleaning agent, and the azeotrope bromopropane/n-hexane can be widely applied as new on-line cleaning agent.
