摘要
用质量隙透法测定了偏苯三酸 -三 -(2 -乙基己 )酯、偏苯三酸三异辛酯和偏苯三酸三异壬酯三种苯多酸酯增塑剂在 5 0~ 10 0℃内的蒸汽压数据 ,并回归出了三种物质的Antoine方程。测定装置以正十六烷和 1-十八烯作标准物质进行了校验 ,测定系统误差约为 5 %
The vapor pressures of three plasticizers including tri 2 ethylexyltrimellitate,tri isooctyltrimellitate and tri isononanyltrimellitate were measured with Kundsen mass effusion method at temperatures from 50 ℃ to 100 ℃, and correlated by Antoine equation. The experimental apparatus was checked with the very low vapor pressures of n hexadecane and 1 octadecene. The measurement error of the system is about 5%. [
