Aromatic reduction

For gas oil sulfur and aromatics reduction serves to increase the cetane number and to improve color and thermal stability. [Pg.402]

The close electrochemical relationship of the simple quinones, (2) and (3), with hydroquinone (1,4-benzenediol) (4) and catechol (1,2-benzenediol) (5), respectively, has proven useful in ways extending beyond their offering an attractive synthetic route. Photographic developers and dye syntheses often involve (4) or its derivatives (10). Biochemists have found much interest in the interaction of mercaptans and amino acids with various compounds related to (3). The reversible redox couple formed in many such examples and the frequendy observed quinonoid chemistry make it difficult to avoid a discussion of the aromatic reduction products of quinones (see Hydroquinone, resorcinol, and catechol). [Pg.403]

The hydroisomerization of light paraffins (C5-C6-C7) to produce their branched isomers is an important industrial process aimed at improving the octane number of the light straight mm stream (LSR). Reformulated gasolines with their impact on olefins and aromatics reduction [26, 27] have increased the number of LSR isomerization units. Table 5.1 gives the octane number of the different C5-C7 linear and branched paraffins. [Pg.137]

Complexes of lapachol with diverse metals like copper (II), iron (II), iron (III), chromium (III), aluminium (IE), yttrium (El), samarium (IE), gadolinium (IE), and dysprosium (IE) have been investigated [141-144]. Direct electrochemical synthesis of some metal derivatives of lapachol have been carried out [145]. Several P-lapachone hydrazo compounds were synthesized and characterized using spectroscopic techniques including X-ray analyses [146]. Selective aromatic reduction in pyranonaphthoquinones has also been reported [147-148]. [Pg.739]

They include aromatic hydroxylation, hydrocarbon and alcohol oxidation, alkene epoxidation, nitro-aromatic reduction, dehydrogenation, carbonylation, cyclization, heterocycle functionalization, etc. [Pg.367]
