Rapid hydrolysis and electrochemical detection of trace carbofuran at a disposable heated screen-printed carbon electrode was written by Wei, Hang;Sun, Jian-Jun;Wang, Yan-Min;Li, Xiao;Chen, Guo-Nan. And the article was included in Analyst (Cambridge, United Kingdom) in 2008.Synthetic Route of C10H12O2 This article mentions the following:

A disposable heated screen-printed carbon electrode (HSPCE) is fabricated. It demonstrates rapid responses to elec. heating and is easily elevated above the water b.p. by a high frequency a.c. The temperature rise at the HSPCE was strongly dependent on the square of the heating current and the electrode width. Carbofuran (CAF) could be rapidly hydrolyzed to carbofuran phenol at the HSPCE with raised temperature, and then determined at the same electrode at room temperature by differential potential voltammetry (DPV). The factors influencing the detection were examined, including pH, hydrolytic temperature and heating time. Under the optimum conditions, the detection linear range of CAF was from 4.0 × 10^-7 to 4.0 × 10^-4 mol L^-1 and the detection limit was 5.0 × 10^-8 mol L^-1 (S/N = 3). This method was successfully applied to the determination of CAF residues in real samples (spiked water, soil and vegetables), and satisfactory recoveries were obtained. In the experiment, the researchers used many compounds, for example, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8Synthetic Route of C10H12O2).

2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8) belongs to benzofurans derivatives. Benzofuran derivatives are one of the most important oxygen-containing heterocycles. Substituted benzofurans find applications such as fluorescent sensors, oxidants, in drug discovery, and in another field of chemistry and agriculture.Synthetic Route of C10H12O2

Microwave-granular activated carbon (MW-GAC) system for carbofuran degradation: Analysis of characteristics and recyclability of the spent GAC was written by Remya, Neelancherry;Lin, Jih-Gaw. And the article was included in Desalination and Water Treatment in 2015.Reference of 1563-38-8 This article mentions the following:

Granular activated carbon (GAC) is frequently used to remove pollutants from wastewater. However, the mechanism of pollutant removal by GAC is by adsorption and hence spent GAC should be regenerated and used for several cycles for minimizing the cost of treatment. In the present study, the characteristics of GAC and carbofuran removal mechanism were explored in a microwave-GAC (MW-GAC) system. Carbofuran removal by adsorption was 52% at a GAC loading of 0.8 g/L. However, complete carbofuran degradation from aqueous solution as well as from GAC surface was obtained within 30 min in a MW-GAC system. In addition, A COD removal efficiency of 72% was observed in the MW-GAC system at pH 8 and 80!!!C after 30 min. The degradation occurred mainly through cleavage of carbamate group and oxidation of furan ring. Carbofuran removal by adsorption was enhanced with MW exposed GAC due to the improvement in the surface property on exposure to MW. On the other hand, recyclability of MW exposed GAC in the MW-GAC system indicated > 99% degradation of carbofuran in all the three cycles tested. As a whole, complete degradation of carbofuran and the effective recycling of the spent GAC could be achieved in the MW-GAC system. In the experiment, the researchers used many compounds, for example, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8Reference of 1563-38-8).

Promising post-consumer PET-derived activated carbon electrode material for non-enzymatic electrochemical determination of carbofuran hydrolysate was written by Ayyalusamy, Sureshkumar;Mishra, Susmita;Suryanarayanan, Vembu. And the article was included in Scientific Reports in 2018.Product Details of 1563-38-8 This article mentions the following:

In this work, activated carbon (AC) materials, prepared from polyethylene terephthalate (PET) waste bottles were used as the sensing platform for the indirect detection of carbofuran. The morphol. and surface properties of the PET-derived AC (PET-AC) were characterized by N₂ adsorption/desorption isotherm, X-ray diffraction (XRD), field-emission scanning/transmission electron microscopy (FE-SEM/TEM) and Raman spectroscopy. The electrochem. activity of the PET-AC modified glassy carbon electrode (GCE) (PET-AC/GCE) was measured by cyclic voltammetry and amperometry. The enhanced surface area and desirable porosities of PET-AC are attributed for the superior electrocatalytic activity on the detection of carbofuran phenol, where, the proposed sensor shows low detection limit (0.03μM) and remarkable sensitivity (0.11μA μM^-1 cm^-2). The PET-AC/GCE holds high selectivity towards potentially interfering species. It also provides desirable stability, repeatability and reproducibility on detection of carbofuran phenol. Furthermore, the proposed sensor is utilized for the detection of carbofuran phenol in real sample applications. The above mentioned unique properties and desirable electrochem. performances suggest that the PET-derived AC is the most suitable carbonaceous materials for cost-effective and non-enzymic electrochem. sensor.

Cine substitution of arenes using the aryl carbamate as a removable directing group was written by Mesganaw, Tehetena;Fine Nathel, Noah F.;Garg, Neil K.. And the article was included in Organic Letters in 2012.SDS of cas: 1563-38-8 This article mentions the following:

An efficient and controlled means to achieve a rare cine substitution of arenes is reported. The methodol. relies on the strategic use of aryl O-carbamates as readily removable directing groups for arene functionalization. The removal of aryl carbamates is achieved by employing an air-stable Ni(II) precatalyst, along with an inexpensive reducing agent, to give synthetically useful yields across a range of substrates. The net cine substitution process offers a new strategy for analog synthesis, which complements the well-established logic for achieving arene functionalization by ipso substitution. In the experiment, the researchers used many compounds, for example, 2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8SDS of cas: 1563-38-8).

2,2-Dimethyl-2,3-dihydrobenzofuran-7-ol (cas: 1563-38-8) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. As benzofurans are prone to undergo ring opening of the heterocycle, examples of reduction of this type of aromatics by using dissolving metals are rather scarce.SDS of cas: 1563-38-8

Hydrothermal Liquefaction of Loblolly Pine: Effects of Various Wastes on Produced Biocrude was written by Saba, Akbar;Lopez, Brandon;Lynam, Joan G.;Reza, M. Toufiq. And the article was included in ACS Omega in 2018.Product Details of 1563-38-8 This article mentions the following:

In this study, feedstock interaction of cow manure and digested sewage sludge on hydrothermal liquefaction (HTL) of loblolly pine (LP) was evaluated. Noncatalytic HTL experiments were performed at reaction temperatures of 250, 275, and 300 °C at a constant reaction time of 30 min. Cyclohexane and acetone were used for biocrude extraction sep. The study focuses on the characteristics of the produced biocrude, and thus, physicochem. properties of biocrudes were examined by gas chromatog.-mass spectrometry, Fourier-transform IR spectroscopy, d., and viscosity measurements, in addition to comparing mass and energy yields. On a LP basis, the biocrude yield reached as high as 30 and 17% for acetone and cyclohexane extraction, resp., at the highest reaction temperature Elemental carbon and energy contents increased with increasing HTL temperature for all cases. Alkalinity of the HTL process liquid (aqueous phase) increases from the HTL of sludge, and thus, it favored the formation of nonpolar compounds in biocrude. On the other hand, acidity of the reaction medium increases with the HTL of manure and pine, and thus, phenolic compounds in biocrude were increasing. Cyclohexane was more effective for sludge/LP biocrude extraction, whereas acetone was effective for manure/LP. D. of cyclohexane extracted sludge/LP biocrudes at 300 °C was less than 1000 kg m^-3, whereas acetone-extracted biocrudes had densities greater than 1000 kg m^-3. For all the biocrudes, viscosity was reduced considerably for the mixtures when compared to biocrudes from LP alone.
