结果表明,这六种醇在20°C~60°C的温度范围内:每一种醇的纯液体表面张力的随温度的升高而呈直线下降现象;相同温度下,醇表面张力的大小依次为乙醇<甲醇< 1-丙醇< 1-丁醇< 1-戊醇< 1-庚醇;醇类密度随温度的变化趋势和醇类表面张力随温度的变化趋势极相同。

Study the different temperature the surface tension of the pure liquid of the 醇 , to choose to use in keeping with pure the measurement method of the liquid surface tension:The capillary rises the method, William's rice hangs a slice of method, the wreath method or the bubble presses the method.Among them, William's rice hangs a slice of method is the most in common use, and more accurate method.This experiment use according to the full-automatic surface tension instrument( BZY-1) that William's rice hangs a slice of method principle to methyl alcohol, have no ether of water,1- C 醇 ,1- the D 醇 ,1- E 醇 ,1- these six kinds of 醇s of G 醇s carry on the measurement of its surface tension number within the scope of 20 ° Cs~60 the temperature of the ° C.After according to the diagraph data, make a following trend diagram:Each surface tension of 醇 changes the curve diagram with the temperature, the series of 醇 is under the different temperature surface tension with the trend di
