Similarities of toluene and o-cresol neuroexcitation in rats

Neurotoxicology and Teratology, 1989
Exposure 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, 1986
Abstract 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, 1965
Abstract 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

Acylation of o-Cresol with Pyromellitic Dianhydride

Petroleum Chemistry, 2019
The 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.

Alkenylation of p- and o-cresols with piperylene

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1961
1. The alkenylation of p- and o-cresols with piperylene in the presence of acid catalysts was studied. 2. Under the conditions used the reaction between p- and o-cresol and piperylene occurs as C-alkenylation. 3. The reaction products between p- and o-cresol and piperylene are isomeric mono- and diisopentenylcresols and their

Ozonation of o-cresol in aqueous solutions

Water Research, 1990
Abstract 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.

Biodegradation of o-Cresol by a Pseudomonas spp

2015
The 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 ...

Flip-flops in fluorinated o-cresol

Chemical Physics Letters, 2000
Abstract 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.

Structural and Torsional Properties of o-Cresol and o-Cresol-OD as Obtained from Microwave Spectroscopy and ab Initio Calculations

Journal of Molecular Spectroscopy, 2002
Abstract The microwave spectra of o -cresol and of o -cresol-OD were assigned using molecular beam Fourier transform microwave (MB-FTMW) spectrometers in the frequency range of 3–40 GHz. Two conformers of o -cresol were measured where the hydroxy group is syn with respect to the methyl group in one case and anti in the other.
