Thermochemistry of Solution, Solvation and Hydrogen Bonding of Chloroform in Linear and Cyclic Ethers

Abstract

In this work the thermochemistry of solution, solvation and hydrogen bond formation of chloroform in linear and cyclic ethers was studied. The infinite dilution solution enthalpies of chloroform in diethyl ether, diglyme, 1,4-dioxane, tetrahydrofuran, 12-crown-4 and 15-crown-5 were measured at 298.15 K. The solvation and hydrogen bonding enthalpies of chloroform in the ethers were calculated. It was found that the hydrogen bonding enthalpies of chloroform in the ethers are significantly higher for linear than for cyclic ethers. The hydrogen bonding of ethers with chloroform was discussed in cases when ethers act as a solute or solvent.
