    Notes: Die Nitrogruppe tritt in 4- und 3-Stellung des Benzocyclobutens ein. Im letztgenannten Fall öffnet sich der Vierring zwischen 1, 7. Eine Ringsprengung an der gleichen Stelle wird bei-der Einwirkung von Salzsäure auf 4-Acetamino-benzo-cyclobuten beobachtet. Ausgehend vom 4-Nitro-benzocyclobuten wurde über die Amino- und Hydroxyverbindung hinweg mit Frémy-Salz Benzocyclobuten-o-chinon-(3.4) dargestellt. Es werden einige Reaktionen mitgeteilt, die mit diesem Strukturvorschlag in Einklang stehen. Zur Erklärung des unsymmetrischen Spaltungsverlaufes wird die Elektronenaffinität des Aromaten im Übergangszustand verantwortlich gemacht.

    Notes: Enthalpies of components in ideal gas mixtures can be computed from existing data. However the isothermal effects of pressure and composition on partial enthalpies of mixture components have not been completely characterized. An investigation of the application of the Redlich-Kwong equation of state to the calculation of partial enthalpies is reported here. Methods are developed for convenient hand calculations and for computations on the IBM-650.Calculated partial enthalpies are compared with values derived from experimental P-V-T-C data for binary hydrocarbon mixtures. The calculated values agree fairly well with the derived data for pressures up to 2,500 lb./sq. in. abs. Best agreement is generally obtained when the mixture is well above the critical temperature of the more abundant component. No consistent bias was indicated however.

    Notes: In continuation of earlier work, another chelating agent containing two different chelating systems in the same molecule (p-nitrobenzeneazotyrosine) was synthesized. 2:1 coordination monomers of this molecule were made and characterized with divalent copper, lead, cobalt, nickel, uranyl, and zinc ions. From these compounds, two types of coordination polymers were synthesized and studied: those involving the ions of one metal bound with both chelating groups in the ligand, and those having two different metals bound in the same polymer chain. Thermal analysis data showed that (among the group under consideration) the bimetallic polymeric chelates have no exceptional stability.
