Abstract

Vapor-liquid equilibrium data for pure species 1‑methoxy-2-propanol, 1‑methoxy-2-propyl acetate, toluene and binary mixtures with toluene was generated using a modified ebulliometer at six different pressures in the range of (100.82 to 60.08) kPa. The parameters of Antoine equation were obtained by regression based on the experimentally determined boiling points of pure species at different pressures. The binary VLE data for the two binary pairs was modeled using Margules 3-suffix, Wilson, NRTL, UNIQUAC and UNIFAC models. NRTL model gave better fit with the experimental data as compared to other models. Toluene – 1‑methoxy-2-propanol system exhibits an azeotrope.

甲苯与1-甲氧基-2-丙醇和1-乙氧基-2-乙酸丙酯等压汽液平衡的库仑法测定

在(100.82至60.08)kPa范围内的六种不同压力下，使用改进的气泡计生成了纯物质1 -甲氧基-2-丙醇、1 -甲氧基-2-丙基乙酸酯、甲苯和甲苯二元混合物的气液平衡数据。根据实验确定的不同压力下纯物质的沸点，通过回归得到了Antoine方程的参数。采用Margules 3-suffix、Wilson、NRTL、UNIQUAC和UNIFAC模型对两对二进制VLE数据进行建模。与其他模型相比，NRTL模型与实验数据的拟合效果较好。甲苯- 1‑甲氧基-2-丙醇体系具有共沸性。

期刊介绍： Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
