The peaks for phenyl acetate and o-cresyl acetate were symmetrical and appeared at 16.12 and 16.63 min, respectively. NIST ThermoData Engine software package

The repeatability, which was represented by relative standard deviations for 10 μg/kg and 100 μg/kg, was 6.24% and 6.14%, respectively (Table 2), indicating a reasonably good accuracy and precision.

Experts answered your questions - watch here! Therefore, the concentration of phenol in fish and in the water needs to be measured in order to protect fish and humans from any possible harmful effects. The reaction between ethanoyl chloride and phenol is similar to the ethanol reaction although not so vigorous. } National Institute of Standards and Technology, Normal boiling temperature (Liquid and Gas), Boiling temperature (Liquid in equilibrium with Gas) as a function of Pressure, Phase boundary pressure (Liquid in equilibrium with Gas) as a function of Temperature, Density (Liquid in equilibrium with Gas) as a function of Temperature, Density (Gas in equilibrium with Liquid) as a function of Temperature, Enthalpy of vaporization or sublimation (Liquid to Gas) as a function of Temperature, Heat capacity at saturation pressure (Liquid in equilibrium with Gas) as a function of Temperature, Heat capacity at constant pressure (Ideal Gas) as a function of Temperature, Enthalpy (Liquid in equilibrium with Gas) as a function of Temperature, Enthalpy (Ideal Gas) as a function of Temperature, Refractive index (Liquid in equilibrium with Gas) as a function of Wavelength and Temperature, Viscosity (Gas) as a function of Temperature and Pressure, Viscosity (Liquid in equilibrium with Gas) as a function of Temperature, Thermal conductivity (Gas) as a function of Temperature and Pressure, Thermal conductivity (Liquid in equilibrium with Gas) as a function of Temperature. Depending on the administered dosage, fish suffer behavioral, respiratory, and lethal effects [4, 5]. The recoveries for 10 μg/kg and 100 μg/kg concentrations were 98.2% and 96.3%, respectively, much higher than those (82.2–86.8%) for fortified 250–1000 μg/kg samples of mackerel [13]. AQA AS Chemistry May 23rd 2019 UNOFFICIAL MARKSCHEME, Chemistry 9-1 GCSE equations and formulae, Chemistry and Physics Paper 1 Equations 9-1, How to get an A* on A-Level Chemistry? Note: These reactions are discussed in rather more detail on a page about reactions of acyl chlorides.

Due to the fact that the concentrations of phenol may be distributed over a large range in the fish tissue samples, two sets of five-point calibration curves were prepared over 2 concentration ranges. margin: 0; Bagheri, H.; Saber, A.; Mousavi, S. R. J. Chromatogr.

This method was essentially developed for analyzing semivolatile organic compounds in water, soil, and municipal sludge, not for biological samples. 1999, 63, 195. To date, no toxicological studies have reported phenol to be carcinogenic for humans. NIST/TRC Web Thermo Tables (WTT) NIST Standard Reference Subscription Database 3 - Professional Edition Version 2-2012-1-Pro This web application provides access to a collection of critically evaluated thermodynamic property data for pure compounds with a primary focus on organics. The mass spectrometer was operated in the electron impact mode for ionization and in the selected ion monitoring mode for quantitation.

Further, the application of this method to other phenol analogs, such as alkylphenols, bisphenols, and chlorinated phenols, can be considered.

The LOQ was lower than the value (100 μg/kg), obtained for mackerel, which was analyzed for phenol itself by GC–MS without a derivatization step [13]. A 2005, 1087, 283.
