Abstract / Full Text

The kinetics of oxyethylation of ethanol and propanol-1 was studied under conditions of base catalysis in the absence of a solvent and in solvents (dodecane, para-xylene, and 1,4-dioxane) at ethylene oxide concentrations in the starting mixture of ~1 M and 10–1–10–3 M of sodium alkoxide catalyst (pressure 1.4 MPa, temperature 80–150°С). As in the case of alcohols С4–С7, the results of experiments are adequately described by the first-order kinetic equation based on the concentration of alcohol associates. The association parameters and their temperature dependences were determined. The behavior of the associates in various solvents was studied. It was assumed that the difference between the association parameters of alcohols С2–С3 and those of alcohols С4–С7 lies in the fact that the former are hydrophilic, while the latter are hydrophobic.
