Flip-flops in fluorinated o-cresol
Chemical Physics Letters, 2000Abstract Ab initio geometry optimizations are used to investigate the side chain fluorinated cis o-cresols, HOC6H4CH3−nFn (n=1, 2, and 3). The three ground states are found to contain hydrogen bonded hexagon, which may flip flop between two equivalent positions relative to the phenyl ring.

Acylation of o-Cresol with Pyromellitic Dianhydride
Petroleum Chemistry, 2019The acylation of o-cresol with pyromellitic dianhydride (PMDA) has been experimentally studied. The optimum conditions of the acylation reaction of o-cresol with PMDA have been determined. The synthesis has been performed in o-cresol melt at 120°C for 30 h at a reactant molar ratio of PMDA : o-cresol : SnCl4 = 1.0 : 4.1 : 2.0.

Ozonation of o-cresol in aqueous solutions
Water Research, 1990Abstract The o -cresol aqueous solution ozonation of concentrations similar to those encountered in some wastewaters has been studied. The degradation rate of o -cresol is increased with temperature, pH, gas flow rate, agitation speed and ozone partial pressure.

Crystallization behavior of α-phenyl o-cresol
Journal of Crystal Growth, 1972The crystallization behavior of α-phenyl o-cresol (o-benzyl phenol) has been investigated over the range of undercooling up to 90 °C. The growth rate reaches a maximum value of about 10-3cm sec-1 at an undercooling of about 30 °C and decreases to about 10-7 cm sec-1 at the lowest temperature of study.

Similarities of toluene and o-cresol neuroexcitation in rats
Neurotoxicology and Teratology, 1989Exposure to high concentrations of toluene vapors, or to intravenous o-cresol (a toluene metabolite) at about 0.9 mg/min, caused excitation of the somatosensory evoked potential (SEP) and EEG of Fischer 344 rats. SEP excitation was characterized by a large increase in a positive waveform at about 20-50 msec. Prolonged exposure to either compound caused

TOXICITY OF o-CRESOL TO MINK AND EUROPEAN FERRETS
Environmental Toxicology and Chemistry, 1986Abstract The toxicity of o-cresol to mink (Mustela vison) and European ferrets (Mustela putorius furo) was evaluated through dietary LC50 and reproduction tests. Twenty-eight-day LC50 tests with each species resulted in no overt signs of toxicity or mortalities, with the highest dietary concentrations being 2,520 ppm for mink and 4,536 ...

The chlorination of O-cresol in organic solvents
Tetrahedron, 1965Abstract A study has been made of the effect of solvent on the mechanism of chlorination of o-cresol. The ratio of 4 chloro-o-cresol:6 chloro-o-cresol produced has been correlated with steric hindrance of the 6-position by hydrogen bonded solvent molecules. Anomalous high yields of 4–6 dichloro-o-cresol in polar solvents at low temperatures have been

Biodegradation of o-Cresol by a Pseudomonas spp
2015The o-cresol is one of the VOCs toxic compounds, it is used as pharmaceutical intermediates, reagents, custom synthesis and as a solvent, disinfectant and chemical intermediate for a wide variety of products including resins, paints and textiles. Efficient treatment technologies are required to reduce o-cresol concentration in wastewater to acceptable ...
