Structure, stability, and hydrogen-bonding interaction in phenol, water, and phenol-water clusters have been investigated using ab initio and density functional theoretical (DFT) methods and using various topological features of electron density. Calculated interaction energies at MP2/6-31G level for ...
Phenol-WaterShape- SizePhenol﹚ater system is important considering its resemblances to biological systems. Here, we explore this phenol﹚ater system to get crucial information on ionic liquids (ILs). Comparative studies on the effect of high melting salts, micelles and ionic liquids (ILs) reveal...
USA) equipped with a UV detector at a wavelength of 270 nm with a flow rate of 1.0 mL min−1. The mobile phase was composed of methanol and pure water (60:40, v/v). Separation was accomplished with an Atlantic C18 column (4.6 nm × 150 nm, 3 μm; Waters...
Simulated aqueous wastewater was prepared by dissolving a calculated amount of phenol in distilled water. The solutions with a concentration of 100 mg/L, 200 mg/L, and 300 mg/L were used for the column experiments. The 100 mg/L phenol solution was prepared by weighing 100 mg (0.1 g) of...
Deionized water was used to prepare all aqueous solutions. 2.2. Experimental procedure 2.2.1. Batch experiment The schematic diagram of the experimental setup is shown in Fig. 1. The ultrasonic transducer converts electrical power from the ultrasonic generator into mechanical energy (ultrasonic waves)...
calibration curve of standard phenol solutions of known concentration by high performance liquid chromatography (HPLC, Waters 2489) using an Accurasil C18 column (4.6 mm 3 150 mm inner diameter, 5 mm particle size) with a mobile phase of methyl alcohol/water (3/7, v/v) pumped at 1 ml/...
principally as a phenol-water azeotrope difficult to remove by simple distillation. Since phenol is well known as a powerful oxidation inhibitor, substantially all of the phenol must be separated from the cumene prior to recycle to the oxidation phase of the process. This has heretofore been accom...
The emulsifier can reduce the Gibbs free energy at the interface between the oil and water phase, and keep the emulsion stability. It leads to the increase of the core content of microcapsules. As a result from the experiment based on the core content of microcapsule, the optimum preparation ...
Besides, the method has high accuracy in the detection of cysteine and phenol at low concentrations in serum and tap water, which lays a foundation for application in the fields of environmental protection and biosensors. Graphical abstract
It has been known for many years that the peroxidase activity of cyclooxygenase 1 and 2 (COX-1 and COX-2) can be reactivated in vitro by the presence of phenol, which serves as a reducing compound, but the underlying mechanism is still poorly understood.
