Mineral degradation mechanisms

Biological. A proposed microbial degradation mechanism is as follows 4-hydroxy-3-methylbenzyl alcohol to 4-hydroxy-3-methylbenzaldehyde to 3-methyl-4-hydroxybenzoic acid to 4-hydroxyisophthalic acid to protocatechuic acid to p ketoadipic acid (Chapman, 1972). In anaerobic sludge, diethyl phthalate degraded as follows monoethyl phthalate to phthalic acid to protocatechuic acid followed by ring cleavage and mineralization (Shelton et al, 1984). [Pg.452]

Prior to discussing the mechanism of thermal degradation of a hybrid system composed of a mineral deposit and an organic modifier, it is advisable to consider the thermal stability and degradation mechanism of neat components. [Pg.30]
