1-Phenylethanol is a chiral flavor compound that has enantiomers, (R)- and (S)-1-phenylethanol, with different flavor properties. Given that isolating these enantiomers from plants is low yielding and costly, enzymatic synthesis presents an alternative approach. However, the genes/enzymes that s...

Whey is a byproduct of the cheese industry, which is potentially dangerous for the environment if it is not treated before its discharge. An alternative use for whey is as raw material to produce compounds with high added value as 2-phenylethanol (2-PE). Experimental production of 2-PE from whey...

Adsorption of 2-phenylethanol from an aqueous solution onto hyper-crossed-linked adsorption resin Macronet MN270 was investigated in a fixed bed column. Adsorption equilibrium was obtained in batch experiments and the results were fitted with the Langmuir isotherm model. A batch adsorption exper...

A quantitative human risk assessment of chloroxylenol was conducted for liquid hand and dishwashing soap products used by consumers and health-care workers. The toxicological data for chloroxylenol indicate lack of genotoxicity, no evidence of carcinogenicity, and minimal systemic toxicity. No o...

Chloroxylenol (PCMX) degradation by thermally activated persulfate (TAP) in aqueous solution and the toxicity changes of the system were investigated. PCMX oxidative degradation followed a pseudo-first-order kinetic model. The apparent activation energy of PCMX degradation was calculated to be 1...

The potential of o-nitrotoluene and p-nitrotoluene to cause cancer in mammalian species was studied in male and female F344/N rats and B6C3F1 mice. These chemicals are on the EPA list of high production chemicals and there is potential for human exposure (High Production Volume Chemical List (20...

The FT-IR and FT-Raman spectra of 2-chloro-4-nitrotoluene and 4-chloro-2-nitrotoluene have been recorded in the regions 4000–400 and 4000–100 cm−1, respectively. The conformational analyses were performed and the energies of the different possible conformers were determined. The geometry of th...

In this paper, H2[email protected] composites were fabricated by the simple hydrothermal method through in-situ growth iron-based metal-organic frameworks (H2N-Fe-MIL-88B) on ordered mesoporous carbon (OMC). Compared with pure H2N-Fe-MIL-88B crystals, the introduction of OMC can shrink the size ...

2-Nitrotoluene (2-NT) is subjected to thermal, photo, and photothermal aging to determine its gas-phase decomposition products via GC/MS. Besides 2-nitrotoluene, the following decomposition products are detected in the gas phase: toluene, 2-nitrosotoluene, 2-cresol, and 2-toluidine. Time resolve...

Novel sandwich PES-SPES/PS-PDVB/PTFE adsorptive membranes were prepared by a filtration/immersion precipitation method and employed for the removal of 4-nitrotoluene from water. The static adsorption thermodynamics, kinetics, dynamic adsorption/desorption and membrane reusability were investigat...

2-nitrotoluene (2-NT) is an important industrial chemical. However, in the past 25 years, serious incidents owing to its thermal decomposition have killed 10 people and injured more than 200. This research focuses on the thermal decomposition of 2-NT using the Advanced Reactive System Screening ...

A new iron-fly ash packing was studied for reductive transformation of p-nitrotoluene. The packing was made of iron, fly ash and kaolin with the mass ratio of 36:7:2. A reactor was designed to investigate the long-term performance of the packing. The results showed that the reduction of p-nitrot...

Carbon “quantum” dots or carbon dots, generally defined as small carbon nanoparticles with various surface passivation schemes, have emerged to represent a rapidly advancing and expanding research field. A wide variety of technological applications of carbon dots have been pursued, including e...

Thermochemical properties of nitrotoluenes are in disarray. New standard (p = 0.1 MPa) molar enthalpies of formation at the temperature T = 298.15 K of the liquid 3-nitrotoluene and crystalline 4-nitrotoluene were measured using high-precision combustion calorimetry. New molar enthalpies of vapo...

In this research, a miniaturized version of matrix solid phase dispersion (MSPD) method was developed for successful extraction of five nitrotoluenes from soil samples. The terpene based deep eutectic solvent (DES) composed of borneol and DL-menthol was used simultaneously as extraction solvent ...

Salicylic acid and three of its derivatives were used to provide antibacterial properties to viscose fabrics. The four bactericides used were bonded to the viscose fabrics using epichlorohydrin or polymer binders. Optimization of the salicylic acid and its derivatives as well as the concentratio...

The compounds Ph4Sb[O(O)CC6H3(OH)2-2,5] (1), Ph4Sb[O(O)CC6H3(OH)2-2,6] (2) and [Ph4Sb]+[Ph4Sb(O2C6H3CO2H)]−(3) were obtained through the interaction of pentaphenylantimony with 2,5-; 2,6- and 2,3-dihydroxybenzoic acids in toluene. The structure of synthesized compounds and the coordination type ...
