Instrumentation and procedures for the cold-vapor atomic absorption determination of mercury have been modified. Samples are analyzed by syringe injection under reducing and non-reducing conditions so as to allow mercury valence state differentiation

A method for the determination of the individual concentrations of mercury(II) and RHg(II) in aqueous solutions is described. The mercury metal produced by reduction with tin(II) is measured by flameless atomic absorption. Selective reduction of merc

Solvent-refined lignite (SRL) can be produced by treating lignite (not dried) with CO-H2, donor solvent and high temperature. This reactive black solid softens at about 150°C, is soluble in many organic solvents, is very low in ash and sulfur, and a

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

As part of a project involving synthesis of model oligomers of coal derived asphaltenes and preasphaltenes, we required bis(2-dibenzofuranyl)methane (1). The successful preparation of 1 was carried out via coupling of 2-lithio-dibenzofuran with 2-for

Anthracene is reduced by CO-H/sub 2/O, CO-H/sub 2/O-H/sub 2/, or H/sub 2/ at 425/sup 0/C and an initial pressure of 1500 psi to dihydroanthracene, 1,2,3,4-tetrahydroanthracene, and methylbenzohydrindene. Hydrocracked products and dimers are formed to

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
