非电解质体系汽液相平衡数据库

非电解质系统汽液相平衡数据库（NEDB）包括约1000种有机化合物的189,000 条二元至四元混合物体系的汽液相平衡实验数据及3000多个活度系数模型参数。NEDB的21个活度系数可以用于相图计算。非电解质体系气液相平衡数据库曾获中国科学院科技进步二等奖和国家自然科学三等奖。该库广泛应用于化工和石油化工分离工程的科学研究、过程开发和工程设计。作为化学主题数据库化合物信息整合的一部分，通过化学主题数据库门户集成检索，可访问到相关信息。

The Non-electrolyte Systems Vapor-Liquid Equilibrium Database (NEDB) contains 189,000 sets of experimental vapor-liquid equilibrium (VLE) data for binary to quaternary mixture systems involving approximately 1,000 organic compounds, alongside over 3,000 activity coefficient model parameters. Twenty-one of the activity coefficients stored in NEDB are applicable for phase diagram calculations. This database has won the Second Prize of the Scientific and Technological Progress Award of the Chinese Academy of Sciences and the Third Prize of the National Natural Science Award. It is widely utilized in scientific research, process development and engineering design for chemical and petrochemical separation engineering. As part of the integrated compound information initiative of the Chemical Themed Database, relevant information can be accessed via the integrated retrieval portal of the Chemical Themed Database.
