The rate of formation of the tetrahydrofuran hydrate has been followed by the concentration changes in a solution having other than 17 moles of water per mole of tetrahydrofuran; the hydrate concentration. The concentration was found to vary in a stepwise manner with breaks at concentrations which correspond to water to tetrahydrofuran mole ratios of 10:1, 8:1, 7:1, 5.5:1, 5:1, 3.5:1, 3:1 and 2.5.1. For each concentration range the slope of the concentration time curve was found to be stirrer rate dependent. It is postulated that the observed results are due to hydrogen bonding in the solution, causing association complexes of definite molar ratios of water to tetrahydrofuran corresponding to the breaks in the concentration‐time curves. The rate would therefore be controlled by diffusion of reactant from one complex to the other.
