有机物闪点计算方法初探

Discussion on Calculation Methods of Organic Flash Point

运用闪点与沸点较好的线性关系,将A.P.Kudehadkert等人提出的计算沸点的方法用来计算闪点,即将lg(11078-Tb)=3.031191-0.499191N2/3转换为一般公式lg(A-Tf)=B-CN12/3,通过二分法和最小二乘原理进行数据拟合,分别得到直链饱和烷烃、直链末端单烯烃、一元醇以及直链饱和一元醛的闪点计算方法。该方法计算制约因素少,平均误差小于3%。

It use the boiling point ealeulation method offered by A.P.Kudehadkert etc. to ealeulate the flash point using the good linear relationship of flash point and boiling point. It ab straets the lg （1 078-Tb）=3.031 91-0.499 91 N^2/3 into lg（A-Tf） =B-CN2/3, and carries out data fitting by dichotomy and princi- ple of least squares. Finally, it get the flash point calculation methods of straight-chain alkanes, straight-chain terminal alkenes, single alcohol and straight-chain saturated fatty aldehyde. This method Constraints is less and average error is within 3%
