Enhancing p-cresol extraction from soil

Chemosphere, 2011
Soil washing is a potential technology for rapid removal of organic hydrocarbons sorbed to soils. In this work, p-cresol desorption with different non-ionic surfactants (Tween 80, Brij 30 and Triton X-100) was compared to cyclodextrine and citrate as solubilizer.

The fate of 2,6-bis-(1′-methyl-14C-heptadecyl)-p-cresol (dioctadecyl-p-cresol-14C) in the rat

Toxicology and Applied Pharmacology, 1967
Abstract The fate of DOPC, 2,6-bis-(1′-methylheptadecyl)-p-cresol, a hindered phenol intended for use as a stabilizer in food packaging, has been studied in rats. Following oral ingestion of 1.0 g/kg doses there are no significant increases in urinary conjugate output, and a large proportion of the dose appears to be unabsorbed. The ingestion of DOPC-

Studies of the physiological effects of 2,6-bis-(1′-methylheptadecyl)-p-cresol (dioctadecyl-p-cresol) in the rat and dog

Toxicology and Applied Pharmacology, 1967
Abstract It has been shown that rats and dogs fed as high as 10,000 ppm of DOPC in the diet for 100 and 90 days, respectively, tolerated the compound with little untoward reaction except for a slight decrease in body weight in one group of rats. No effects were noted on behavior, utilization of food, appearance, and stools nor were there any dose ...

Montmorillonite for selective hydroxyalkylation of p-cresol

Applied Clay Science, 2009
Abstract Performances of montmorillonite titanium silicate (TS-1) and dodecatungstophosphoric acid (DTP) were compared for the hydroxyalkylation of p-cresol into dihydroxydiarylmethane (DAM). Ammonia TPD studies of various catalysts showed that an appropriate combination of both strong and weak acid sites of montmorillonite was mainly responsible ...

Condensation of p-cresol with carbon tetrachloride

Journal of the Chemical Society C: Organic, 1966
p-Cresol has been condensed with carbon tetrachloride in the presence of anhydrous zinc chloride as catalyst. The products were di-p-tolyl carbonate, p-tolyl 2-hydroxy-5-methylbenzoate, 2,7-dimethylxanthone, 2,2′-dihydroxy-5,5′-dimethyldiphenylmethane, and 2,2′,2″-trihydroxy-5,5′,5″-trimethyltriphenylmethane. The predicted dihydroxydimethylbenzophenone

The vibrational spectra of p-cresol

Spectrochimica Acta, 1965
Abstract The infrared and Raman spectra of p-cresol have been obtained and a complete vibrational assignment of this molecule has been made. Three deuterated derivatives of p-cresol have been prepared. The infrared and Raman spectra of the deuterated species have also been studied and the assignments of these molecules were used to substantiate the ...

Tolerance of nitrifying sludge to p-cresol

Biotechnology Letters, 2002
p-Cresol at 17 mg l−1 in a nitrifying culture inhibited by 70% nitrate formation whereas at 10 mg l−1 there was no effect. p-Cresol at 220, 470, and 910 mg l−1 was converted to intermediates after adaptation times of 8 h, 24 h, and 40 h, respectively. The sludge recovered 44% of its activity after transformation of p-cresol.

p-Cresol and Cardiovascular Risk in Kidney Transplant Recipients

Transplantation Proceedings, 2015
p-Cresol Sulphate (pCS) is a uremic toxin that originates exclusively from dietary sources and has a high plasma level related to chronic kidney disease (CKD) and cardiovascular disease (CVD). The aim of our study was to evaluate the plasma levels of pCS in kidney transplant recipients (KTRs) related to estimated glomerular filtration rate (eGFR ...

Catalytic alkylation of p-cresol with dipropenyl

Bulletin of the Academy of Sciences, USSR Division of Chemical Science, 1963
1. Alkylation of p-cresol with dipropenyl in the presence of ethylsulfuric acid and zinc chloride on aluminum oxide takes place more readily than alkylation with divinyl and piperylene. 2. The reaction proceeds as a C-alkylation; formation of neutral products of cyclization of isohexenyl-pcresol has not been detected.

A Sensor for the Detection of p-Cresol in Air

1994
The odor of piggeries is unpleasantly distinctive and derives from the volatile components of pig feces, principally p-cresol, skatole, and hydrogen sulfide. With the increasingly urban location of piggeries, nuisance odor is a cause of concern for neighbors and operators alike.
