N-Decane+n-Undecane+n-Tridecane 계의 인화점 측정과 계산

Abstract

Flash point is the most important property that characterize the explosion and fire hazard of liquid mixture. In this paper, flash points of ternary liquid mixture, which is n-decane+n-undecane+n-tridecane system, were measured with Seta flash tester. Measured values were compared with calculated values through Raoult’s law and multiple regression analysis. Absolute average error of the result calculated by Raoult’s law is 1.2 ℃. Absolute average error of the result calculated by multiple regression analysis is 1.0 ℃. As can be seen from absolute average error, the values calculated through multiple regression analysis are more effective than those calculated according to Raoult’s law.
