In work a thermochemistry of solution, solvation and hydrogen bond formation of linear (diethyl ether and diglyme) and cyclic ethers (1,4-dioxane, 12-crown-4, 15-crown-5 and 18-crown-6) in proton acceptor and proton donor solvents were studied. The infinite dilution solution enthalpies of ethers in cyclohexane, carbon tetrachloride, benzene, ethyl acetate, N,N-dimethylformamide, dimethylsulfoxide, acetone, pyridine, chloroform and methanol were measured at 298.15 K. The solvation and hydrogen bonding enthalpies of ethers in the solvent are calculated. The influence of number of active centers in ethers on thermochemical parameters is shown. It was found that the formation of hydrogen bonds for linear and cyclic ethers with proton donors are different.
