Tyger, Tyger, burning bright, In the forests of the night What immortal hand or eye, Could frame thy fearful symmetry? William Blake (london, 28 November 1757-12 august 1827) the poem The Tyger (six stanzas in length, each stanza four lines long) was published in 1794 as part of Blake's illuminated book Songs of Experience (a sequel to Songs of Innocence, published in 1789). reproduced from Songs of Experience, quotation in the public domain.

“…The infinite dilution activity coefficient (IDAC) is a common attributor of all other excess thermodynamic properties, including partial molar excess functions such as enthalpy, entropy, and Gibbs free energy, as well as selectivity and capacity values . IDAC measurements can be determined by several techniques, including inert gas stripping, differential static cell, head space chromatography, and gas–liquid chromatography (GLC). , This study used GLC to determine the infinite dilution activity coefficient values of different organic solutes of different functional groups, including alkanes, alkenes, alkynes, cycloalkanes, cycloalkenes, aromatics, alcohols, ketones, and water in ethaline (1:2 molar ratio) at different temperatures and ambient pressures. In addition, the present study uses the method adopted from the previous studies, such as Manyoni, Kabane, and Redhi, Manyoni and Redhi, and Nkosi, Tumba, and Ramsuroop …”

This paper presents excess thermodynamic data of a mixture of choline chloride, a hydrogen bond acceptor (HBA), and ethylene glycol, a hydrogen bond donor (HBD), with a molar ratio of 1:2, correspondingly. This mixture is popularly known as ethaline. A gas−liquid chromatograph (GLC) fitted with a thermal conductivity detector (TCD) was used to determine infinite dilution activity coefficient (IDAC) values of different functional groups (e.g., alkanes, alkenes, alkynes, cycloalkanes, aromatics, alcohols, ketones, and water) for 32 different organic solutes at different temperatures (T = 313.15−343.15 K) and air pressures. The partial excess molar properties, including Gibbs free energy, enthalpy, and entropy, were computed from the infinite dilution activity coefficient measurements at T = 323.15 K. Furthermore, the separation performance of common separation problems, i.e., hexane/ benzene, cyclohexane/hexane, ethanol/toluene, and acetone/methanol, was evaluated through the selectivity and capacity values, and this was also computed from the infinite dilution activity coefficient values. It was found that ethaline could not be suitable for prospective separation issues, as a result of the poor thermodynamic data that were measured.
