The 103d regular meeting of the society was held on May 12, 1898. The first paper of the evening was presented by Messrs. F. K. Cameron and H. A. Holly and was entitled Acetone-chloroform, Ist paper." Acetone-chloroform is produced by bringing together acetone and chloroform, and adding powdered potassium hydroxide to the cooled mixture in small portions at a time, allowing to stand until the reaction is completed, and fractionating the liquid products. The experiments which are described by the authors have led them to the following conclusions: I. The existence of but one acetone-chloroform, a white, crystalline solid, a derivative of trimethylcarbinol. II. The substance is not a simple addition-product and cannot be resolved into its original constituents by direct means. III. The substance forms no definite hydrate. IV. The temperature of the quadruple point for solid, two solutions and vapor in the system acetone-chloroform-water, is 75.2°. V. The melting-point is near, but above 97°, and in all probability perfectly anhydrous material has not yet been obtained. VI. The system acetone-chloroform and water seems to present the remarkable case of a solid solution and two liquid solutions. The next paper was presented by Messrs. P. Fireman and E. G. Portner and was entitled "The Action of Normal Propyl Alcohol on Phosphonium Iodid." The authors, having undertaken to fill up some of the most important gaps in our knowledge of individual phosphius, communicated, as the first contribution, the method by which they prepared tri-n-propylphosphin and tetra-n-propylphosphonium iodide, and described the properties of these bodies. Messrs. F. K. Cameron and E. F. Thayer presented a paper on "The Boiling-point Curve for Benzene-alcohol Solutions." When a mixture of pure benzene and alcohol containing more than 66.5 per cent. of benzene is partially distilled, it will yield a distillate richer in alcohol. Complete fractional distillation will yield a mixture with a minimum constant boiling-point of 66.7 and containing. 66.5 per cent. of benzene, and a residue of pure benzene. If the original solution contained less than 66.5 per cent. of benzene, it will yield a distillate richer in benzene, and complete fractioning will ultimately yield a distillate of the constant boiling solution, and a residue of pure alcohol. Under no circumstances can a complete separation of the two compounds be obtained by any process of distillation. The last paper of the evening was presented by Mr. F. K. Cameron and was entitled "The Benzoyl Ester of Acethydroxamic Acid." The benzoyl ester of acethydroxamic acid was obtained by Jones as a product of the reaction between sodium isonitroethane and benzoyl chloride. If ligroïn be added to the motherliquor obtained by the crystallization of the substance from ether, another compound is precipitated, isomeric with the first. The isomer is, on standing, gradually but completely converted into the first modification. Jones regards it as a probable ester of acethydroximic acid, the relative orientations of the molecules being indicated thus: The authors have studied the two modifications, designating, for purposes of convenience, the former as the a-compound and the latter as the B-compound, and have arrived at the following conclusions: I. Both modifications exist in the liquid phase. II. The a, or less fusible modification, is the stable one at ordinary temperatues. III. Crystals of the ẞ compound can be obtained by dissolving the a compound and precipitating the ester suddenly from solution. IV. The equilibrium concentration changes with the temper ature. V. The a compound is converted into the ẞ compound with absorption of heat. VI. By raising the temperature of the system, and cooling suddenly, the point of solidification may be brought below the stable triple point. It was not possible to realize the eutectic point in this manner, because of decomposition of the substance. VII. The eutectic point of the system was shown to be below 66°, and is near 65°.
