Behaviour of dichloromethane in solution with hydrocarbons and esters using a database with properties generated in the mixing processes

Abstract

This work studies the behaviour of a set of binary systems formed by dichloromethane, as the common compound, with six alkanes with an even number of carbon atoms (from hexane to hexadecane), as well as twenty-three alkyl (methyl to pentyl) alkanoates (methanoate to pentanoate). The energetic/volumetric effects produced by the mixing processes were determined point-by-point and represented analytically and graphically using a correlation equation that considers the physical nature of the compounds involved in the binary solutions. This study is a part of a working project investigating the behaviour of halogenated compounds with other compounds and, in this case, expanding knowledge of their interactions in solution. The information used, in the form of ( x1 , y(E) /Jmol(-1) ) with y(E) = h(E) or pv(E) is considered to be original and consists of over 10 0 0 discrete points measured isothermally at T = 298.15 K and isobarically at atmospheric pressure of similar to 98 kPa. The information used is of interest and provides significant value to different sectors, both academic and industrial. The impact of the information provided on the theoretical modeling of behaviour of compounds in fluid state, both pure and in solution, is especially valued. (c) 2025 The Author(s).
