The metathesis of 1,5-cyclooctadiene (COD) was investigated over supported rhenium oxide catalysts in terms of carrier effects, acid properties of the catalysts, product distributions, and the reversibility of the reaction. Only alumina plays an effe

The properties of the heavy organic products (b.p. above 420°C, coal liquid bottom, CLB) derived from Victorian brown coal under various liquefaction conditions (temperature of 430–470°C, pressure of 9.8–24.5 MPa and solvent or bottom recycle m

The esterification of b6nzaldehyde has been studiedi over solid NaOH, NaOH-SiO2, A120s, SrO2, BaOz, SrO and CaO. The catalytic'activity was found not. only to closely relate with the basic properties, but also to relate, with the acidic proPerties (F

The metathesis of cyclooctadiene was studied over fourteen kinds of oxides or binary oxides at 40°C in a liquid phase. Only Re2O7–Al2O3 was found to be active. The conversion was 100 % when the concentration of cyclooctadiene was low and the selec

Comparison of laboratory-deashed samples of solvent-refined lignite, subbituminous and bituminous coals on the basis of gross combustion analysis, acid and basic titres, molecular weight, nuclear magnetic resonance, ultraviolet and electron spin reso

Aromaticities (fa) determined for several solvent-refined coals (SRC) by 13C n.m.r. in sym-triazine solution and by the Brown and Ladner 1H n.m.r. technique have been found to be the same within experimental error (0.01). Use of sym-triazine to deter

When benzaldehyde was treated at 120-200 C over BeO, MgO, CaO, SrO or BaO without any solvent, a large amount of benzyl benzoate and a very small amount of benzyl alcohol were found as the raction products. The time variation of the ester formation g

Solvent-refined lignite (SRL) and bituminous coals (SRC) are only partially soluble in good standard carbon-13 n.m.r. solvents. A survey of other possible solvents for SRLs and SRCs showed that sym-triazine at 86 °C solvated SRL as well as pyridine,
