乙酸乙烯醋密度温度校正系数的测定及其应用

The Determination and Application of the Temperature Correction Coefficient for the Density of Vinyl Acetate

通过比重瓶法和密度计法相结合的方案,测定了外售乙酸乙烯酯的密度,并根据最小二乘法的原理,运用线性回归法,求得乙酸乙烯酯密度的温度校正系数,并在外售乙酸乙烯酯的液体重量计量工作中得到应用。

The density of V_(AC) product was determined viacombination of the gravity bottle method and the densimeter method. The temperature correction coefficient for the fdensity of VAC was obtained by least-square method and the linear regression method and has been ap- plied to the liquid gravity metering for the VAc products.
