Optimum conditions for the vapor phase conversion of 1,1-diphenylethane to styrene and benzene over activated Morden bentonite have been found to be a temperature of 600 °C., rapid feed rates, and the use of water vapor as diluent. Ethylbenzene has been found in the reaction products as a hydrogenation product. Styrene content has been found to be dependent directly upon vapor velocity while the conversion efficiency was found to be related directly to the use of water vapor as an inhibitor of carbon deposition on the catalyst.

Cliona Celata

Clionamide, the major metabolite of the burrowing sponge Cliona celata, has been isolated. The structure of clionamide (1) was shown to be (2S)-N-((1E)-5,6,7-trihydroxystyr-1-yl)-2-amino-3-(6-bromoindol-3-yl)propionamide by spectral analysis and by interconversion to its tetracetyl derivative 2. The structure of 2 was determined from spectral data and extensive chemical degradation and was confirmed by the synthesis of its ultimate hydrogenation product, N-(5,6,7-triacetoxypheneth-1-yl)-2-acetamido-3-(indol-3-yl)propionamide (11).

Minor Alkaloid

(+)-Sparteine, (–)-N-methylcytisine, (–)-anagyrine, (–)-baptifoline, (±)-piptanthine and (–)-16-epiormosanine have been isolated as alkaloids of H. linearis R.Br. The absolute configuration of (–)-16-epiormosanine has been established by its formation as an hydrogenation product of the alkaloid (–)-podopetaline. Another minor alkaloid may be a new isomer of ormosanine.

. In connection with the emerging demand for gasoline solvent with a low content of aromatic hydrocarbons we carrier out the analysis of intermediate products obtained in JSC " ANHK " suitable for the producing of the solvent. The most suitable for the separation of the fraction are gaso line fractions producing from the hydrogenation product of the hydrocracking of light vacuum gas oil and the hydrogenation product of high conversion hydrogenation of the heavy middle distillate frac tions. We performed work on the recovery of a narrow fraction of gasoline solvent and its tests for compliance with the requirements.
