Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 707-07-3, Name is (Trimethoxymethyl)benzene, molecular formula is , belongs to ethers-buliding-blocks compound.

Extractive removal of micro and trace nitrofen, 2, 4-dichlorophenol and p-nitrotrophenol from water/soil by humic acid ester ether
The amphiphilic humic acid ester ether (HAEE), as a kind of solid-phase extractant with characteristics of easy separation and hydrophilic-hydrophobic amphiphilic property, was prepared and used to extract micro or trace nitrofen, 2,4-dichlorophenol and p-nitrotrophenol (NIPs) from water and soil. Degradation of NIPs and extractant regeneration were carried out by simple photocatalysis. The adsorption equilibrium of the mono- or three mixed NIPs by HAEE in aqueous could be quickly reached within 20 min. The adsorption process was fit to quasi-second-order kinetics model and Friendlich thermodynamics model. The possible adsorption interaction was discussed. Results suggested that the adsorption of NIPs onto HAEE predominated by hydrogen bonding, hydrophobic interaction and pi-pi interaction. The extraction capacity of mixed NIPs (80 mu g/L each component) by HAEE was up to 0.38 mg/g and tended to be multi-layer adsorption, in which p-nitrotrophenol had higher adsorption competitiveness because of lower resistance to HAEE. When HAEE-NIPs were degraded by photo-catalyst Fe-0/F-TiO2 for 8 h, not only the adsorbed NIPs could be totally degraded and mineralized, but also the HAEE could be effectively regenerated. When the NIPs were continuously extracted from 40-year aging soil for three times (regenerative twice) by combined extractant (48 mL H2O + 2 mL n-hexane + 0.1 g HAEE), the total extraction efficiency of NIPs could reach to 84.66%. This research could supplement the theory and technique for harmless treatment of NIPs contaminated water and soil.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 707-07-3, in my other articles.
