Today, there is an exponential increase in the number of publications devoted to the study of the properties of deep eutectic solvents (DES). According to google.scholar, the total number of scientific articles and patents is approximately 70,000, that contain phrase «deep eutectic solvent». Despite the huge amount of information on the properties of DES, there is no systematic presentation of the physicochemical properties of this type of solvent in the scientific literature. The goal of this project is to create a database that will contain information on the basic physico-chemical properties of DES with the ability to export values for their further use for both scientific and technological purposes. The following properties were included in database: density, isobaric heat capacity, viscosity, speed of sound, thermal conductivity, surface tension, refractive index. The database displays the dependence of the listed properties on temperature, concentration of solution components and pressure. The database pays special attention to the reliability of the values it contains. For each property, the experimental method is indicated, as well as the uncertainties of the properties and the conditions under which the measurements were made. Data search is carried out for two-component anhydrous DES or for their three-component systems with water. For this purpose, the program has created search lines with the ability to write down component systems in the form of common names in Russian or English, CAS numbers and empirical chemical formulas. It is possible to select systems with maximum or minimum property values under given conditions.The database also provides links to primary sources in the form of an article title and a link in doi format. The program has several reporting methods: in the form of tables and graphs. The structure of database is presented in Figure 1. The database was implemented in MySQL and was filled out through a form created using the Yii framework in PHP. The work was supported by the Ministry of Science and Higher Education of the Russian Federation (State Assignment No. 075-01252-22-03 dated 26.10.2022)
