We are very pleased to present a Virtual Special Issue collecting together manuscripts from the 16th International Conference on Properties and Phase Equilibria for Product and Process Design which took place in La Pineda, Tarragona, Spain, on May 21–25, 2023 (PPEPPD-2023). PPEPPD is arguably the most prestigious international meeting in the field of molecular thermodynamics and phase equilibria. The community is very grateful to Lourdes Vega (chair), Félix Llovell (vice chair), and Ioannis Economou (vice chair) for organizing PPEPPD-2023, providing great hospitality, and bringing the community together at the beautiful Costa Dorada. The PPEPPD conference series began in 1977 to provide an effective forum for academic and industrial researchers to meet and communicate on the status and future trends in properties and phase equilibria, important to the design of products or processes. PPEPPD-2023 featured a series of invited talks led off by an inspirational keynote talk on Circular chemistry–reengineering our relationship with the planet presented by Javier García-Martínez, President of IUPAC. Much knowledge was shared during oral and poster sessions and two workshops. PPEPPD-2023 also included the bestowing of the Young Researcher Award on Otto Moultos, Delft University of Technology, The Netherlands, and of the John M. Prausnitz Award on Ilja Siepmann, University of Minnesota, USA. We are grateful to the PPEPPD-2023 conference chairs, International Organizing Committee, and International Advisory Board for the opportunity to publish manuscripts from this important conference in the Journal of Chemical& Engineering Data. Additional articles can be found in a special issue of Fluid Phase Equilibria. The following five papers report results presented at PPEPPD-2023: Density, Viscosity, CO2 and CH4 Solubility, and CO2/CH4 Selectivity of Protic and Aprotic Imidazolium and Ammonium Bis(trifluoromethanesulfonyl)amide and Tetrafluoroborate Ionic Liquids; Yuki Suzuki, Masaki Watanabe, Daisuke Kodama, Takashi Makino, Mitsuhiro Kanakubo, and Masakazu Sasaki High Pressure Densities and Derived Thermodynamic Properties of Pure (1R)-(+)-α-Pinene, (1S)-(−)-β-Pinene, and Linalool: Experiment and Modeling; Nikola Grozdanić, Zoran Simić, Mirjana Kijevčanin, and Ivona Radović Estimation of the Compressibility Factor of Nanoconfined Alkanes along Vapor–Liquid Coexistence; Sudhir Kumar Singh Liquid–Liquid Extraction of Some Biomolecules in the ATPS {Ethyl Lactate (1) + Sodium Potassium Tartrate (2) + Water (3)} at 298.15 K and 0.1 MPa; Pedro Velho and Eugénia A. Macedo Vapor–Liquid Equilibrium Phase Behavior of Binary Systems of Carbon Dioxide with Eugenol or Guaiacol; Ardila Hayu Tiwikrama, Salal Hasan Khudaida, and Ching-Yu Long This article has not yet been cited by other publications.

PPEPPD 2023 虚拟特刊序言

我们很高兴推出虚拟特刊，收集了 2023 年 5 月 21 日至 25 日在西班牙塔拉戈纳拉皮内达举行的第 16 届产品和工艺设计性能与相平衡国际会议 (PPEPPD-2023 ）。PPEPPD 可以说是分子热力学和相平衡领域最负盛名的国际会议。社区非常感谢 Lourdes Vega（主席）、Félix Llovell（副主席）和 Ioannis Economou（副主席）组织 PPEPPD-2023，提供热情的款待，并将社区聚集在美丽的黄金海岸。PPEPPD 会议系列始于 1977 年，旨在为学术和工业研究人员提供一个有效的论坛，让他们就性能和相平衡的现状和未来趋势进行会面和交流，这对产品或工艺的设计很重要。PPEPPD-2023 包括一系列受邀演讲，由IUPAC 主席哈维尔·加西亚·马丁内斯 (Javier García-Martínez) 发表的关于循环化学——重新设计我们与地球的关系的鼓舞人心的主题演讲拉开帷幕。在口头和海报会议以及两次研讨会上分享了很多知识。PPEPPD-2023 还包括向荷兰代尔夫特理工大学的 Otto Moultos 授予青年研究员奖，以及向美国明尼苏达大学的 Ilja Siepmann 授予 John M. Prausnitz 奖。我们感谢 PPEPPD-2023 会议主席、国际组委会和国际顾问委员会给我们机会在《化学与工程数据杂志》上发表本次重要会议的手稿。其他文章可以在Fluid Phase Equilibria特刊中找到。以下五篇论文报告了 PPEPPD-2023 上发表的结果：质子和非质子咪唑鎓、双(三氟甲磺酰基)酰胺铵和四氟硼酸盐离子液体的密度、粘度、CO2 和 CH4 溶解度以及 CO2/CH4 选择性；Yuki Suzuki、Masaki Watanabe、Daisuke Kodama、Takashi Makino、Mitsuhiro Kanakubo 和 Masakazu Sasaki 纯 (1R)-(+)-α-蒎烯、(1S)-(−)-β-蒎烯的高压密度和衍生热力学性质和芳樟醇：实验和建模；Nikola Grozdanić、Zoran Simić、Mirjana Kijevčanin 和 Ivona Radović 气液共存时纳米受限烷烃的压缩系数估计；Sudhir Kumar Singh 在 298.15 K 和 0.1 MPa 下对 ATPS {乳酸乙酯 (1) + 酒石酸钠钾 (2) + 水 (3)} 中的一些生物分子进行液-液萃取；Pedro Velho 和 Eugénia A. Macedo 二氧化碳与丁子香酚或愈创木酚二元体系的汽液平衡相行为；Ardila Hayu Tiwikrama、Salal Hasan Khudaida 和 Ching-Yu Long 本文尚未被其他出版物引用。
