Biomass, a renewable carbon source which can be processed using biorefinery system as an alternative of the conventional petroleum-based refineries. Aromatic precursor molecule synthesis involves chemical fossil-fuel-based starting materials, such benzene and xylene. These energy-intensive processes are usually producing many byproducts along with desired molecule. If aromatic molecules extract...

1. A number of tissues, in particular, brain, liver, and kidney, incubated aerobically in vitro as slices or ground suspensions produce a compound which combines with p-aminobenzoic acid in acid solution to form a yellow color. 2. A study of this reaction in rat brain has shown that this compound can be produced when washed boiled brain protein is incubated aerobically with ascorbic acid. The l...

The stability constants and related thermodynamic functions characterizing the formation of divalent Ni, Cu, Zn, Cd and Hg complexes with oand p-aminobenzoic acid hydrazide were determined potentiometrically at different temperatures. The formations of the complexes are endothermic processes. The formed bonds are mainly electrostatic. Conductometric titration was carried out to determine the st...
