焦油水分测定方法的改进

Improved Method for Determining Moisture Content in Tar

介绍了直接加入电石测定焦油水分的称量法,并且与蒸馏法进行了对照,用新方法测定的焦油样,其精密度和准确度较高。

The gravimetry method by directly adding calcium carbide to determine the moisture content in tar was introduced, and was compared with the distillation method. The new method is more accurate and precise.
