在文献中有关正戊醇及正庚醇黏度特性的记载为数不多,要根据现有的实验数据来确定黏度与温度的关系是相当困难的。本工作的目的即是在比较大的温度范围内测定上述两个醇的黏度及密度,并推求实验数据的经验方程式。本实验所用的正戊醇系将市售最纯品加氧化钙干燥、精馏而得,其沸点范围是135.0—135.5℃(721.5毫米汞柱);正庚醇系按照[4]中所记载的方法由还原正庚醛 In the literature, there are only a few records on the viscosity characteristics of n-pentanol and n-heptanol. It is quite difficult to determine the relationship between viscosity and temperature based on the available experimental data. The purpose of this work is to measure the viscosity and density of the above two alcohols in a relatively large temperature range and to derive empirical equations for the experimental data. The n-amyl alcohol used in this experiment was obtained by drying the most pure calcium oxide commercially available and having a boiling range of 135.0-135.5 ° C (721.5 mmHg). The n-heptanol was obtained as described in [4] The method consists of reducing n-heptanal
