Usage

General Description

4,4'-Ethylenedianisole is a chemical compound with the formula C14H14O2. It is an aromatic ether that is used primarily as a monomer in the production of poly(arylene ether) resins, which are high-performance thermoplastic materials known for their excellent mechanical, thermal, and chemical properties. 4,4'-Ethylenedianisole is also used as a building block in the synthesis of various specialty chemicals and polymers. 4,4'-Ethylenedianisole has a molecular weight of 214.26 g/mol and is a colorless to pale yellow liquid at room temperature. It is considered to have low acute toxicity, but its long-term effects on human health and the environment are not well documented. Therefore, proper handling and disposal procedures are recommended when working with this compound.

Synthesis of ethylene bis [(2-hydroxy-5,1,3-phenylene) bis methylene] tetraphosphonic acid and their anticorrosive effect on carbon steel in 3%NaCl solution

The inhibition performance of the newly synthesized Ethylene bis [(2-hydroxy-5,1,3-phenylene) bis methylene] tetraphosphonic acid (ETPA) toward carbon steel in 3% NaCl was investigated at different concentrations using potentiodynamic polarization (PDP) and impedance spectroscopy (EIS) methods. It was found that the inhibition capability was increased with increasing inhibitor dose and reach 92% at 10?3 mol/L. Also, Polarization curves showed that ETPA acts as a mixed type inhibitor with predominantly control of anodic reaction. The new inhibitor was investigated by different spectroscopic methods such as 1H, 13C and 31PNMR. The quantum parameters such as absolute electronegativity (χ), energy gap ΔE (EHOMO-ELUMO), global softness (σ), global hardness (η), electrophilicity index (ω) and the number of transfer electrons (ΔN) are calculated by density functional theory (DFT). The experimental also correlated with density functional theory results. The calculations show that ETPA has high density of negative charge located on the oxygen atoms of the phosphonate group facilitating the adsorption of ETPA on the surface of carbon steel. The inhibition efficiency of ETPA was discussed in terms of blocking of electrode surface by adsorption of ETPA molecules through active centers. The adsorption of ETPA on the surface of carbon steel obeyed the Langmuir isotherm paradigm.

A heavy-metal-free desulfonylative Giese-type reaction of benzothiazole sulfones under visible-light conditions

A visible-light-induced desulfonylative Giese-type reaction has been developed. Essential to the success is the employment of Hantzsch ester to activate benzothiazole sulfones without any heavy-metal additives. Not only benzylic benzothiazole sulfones but also alkyl ones were viable substrates and reacted with electron-deficient alkenes and a propiol amide.
