中文摘要 | 本文以一般的Ostwald比重瓶及黏度計,量測純質MIBK及2-EH及25,30,35,40,45,50,55在60 ℃的密度與黏度。這些實驗數據,不只準確度高,且為目前文獻上所欠缺。四種依據官能基貢獻方法的經驗推測方程式中,以Thomas方程式最能準確的估算MIBK黏度,但對於2-EH,則四種推測方程式皆失效,關於溫度-黏度效應,本文採用的二種二參數經驗式的推測值,都能和實驗值獲得相當程度的共聯。 |
英文摘要 | Densities and viscosities of pure MIBK and 2-EH have been determined at temperatures of 25, 30, 35, 40, 45, 50, 55 and 60℃ by means of a commercially available Otswald pycnometer and Ostwald viscometer. These measurements are not only with high degree of accuracy but are also lacking in the current literature. Assessment of four group-contribution estimation methods reveals that the Thomas method far outstrips the others in predicting the viscosities of MIBK, but all fail in the case of 2-EH. In regard to the temperature-viscosity behavior, observed viscosity data of both MIBK and 2-EH are well correlated by two frequently employed two-parameter empirical equations. |
