Gas Reactions

Ethylidene dibutyrate and heptylidene diacetate decompose in the vapor state at temperatures between 200° and 300 °C. to form an aldehyde and an anhydride. The reactions are homogeneous, unimolecular, and complete. The activation energy is the same as that previously found for other members of this homologous series. Ethylidene dibutyrate decomposes at the same rate as ethylidene diacetate, and thus provides further evidence that the specific reaction velocity is independent of the size of the anhydride radicals. Heptylidene diacetate decomposes at the same rate as butylidene diacetate. This indicates that after the aldehyde radical has attained a certain size (three or four carbon atoms) the addition of –CH2− groups leaves the specific reaction velocity unchanged. The velocity constants are given by the equations[Formula: see text]

Normal Coordinate Calculation

The infrared spectra of 1-chloropropyne and 1-chloropropyne-d3 have been investigated in the vapor state, in solution, and, in part, in the liquid over the spectral region 3 to 35 μ. Intensities of the infrared bands have been measured from the spectra of the solutions. The Raman spectra of the compounds in the liquid state, together with standard intensities and depolarization ratios of the Raman bands, were obtained. A complete assignment, based on a normal-coordinate calculation of the fundamentals, has been made. Coriolis coupling coefficients of three of the perpendicular-type fundamentals of CH3≡CCl were determined and those of the other two shown to be near unity. Two coupling coefficients for CD3C≡CCl were obtained. The potential function and isotope effects on Raman intensity and Raman displacement of the CCl stretching vibration are discussed.
