     the effect of acetone on chclf2 hydrate equilibrium conditions has been investigated. a full view equilibrium cell and associated equipment are designed, fabricated and used for this purpose. adding acetone caused an increase of the equilibrium pressure. the equilibrium conditions were measured in the pressure range of 32 to 112 psia. the investigated concentrations of acetone in water were 2, 4, and 6 mole%. in contrast to methane hydrate in the presence of acetone, the system of chclf2 + acetone + water shows inhibition effect for all of the above concentration of acetone.the existing model for structure ii hydrates in the ternary mixtures of methane + water + acetone has been applied for the above system.the measured dissociation temperatures have been compared with the results of this model.
