| 摘 要： | 本文采用经改进了的差分最大气泡压力法建立了一套表面张力测定装置，并对装置进行了测试。用该装置测定了对二甲苯和醋酸体系在常压下，30℃～70℃范围内，不同浓度下的表面张力，并用两种方法对数据进行了关联，为PTA的工程设计提供既方便又可靠的基础数据。

| Abstract: | The equipment for surface tension measurement by the improved differential maximum bubble pressure method was built and tested. The surface tension of a binary mixture of p-xylene and acetic acid was measured over the entire concentration range from 303.15 K to 343.15 K under atmospheric pressure. The experimental values were correlated with two methods. It is useful for PTA plant design. |
