1967-31-3 Usage

General Description

2-chloroterephthalic acid, also known as 2-chloro-1,4-benzenedicarboxylic acid, is a chemical compound classified under the category of benzenoids. Its molecular formula is C8H5ClO4 and it has a molar mass of 202.57 g/mol. It features a benzene ring as part of its structure, with one of the hydrogen atoms replaced by a chlorine atom and two of the carbon atoms on the ring bonded to carboxylic acid groups. This particular acid is not widely discussed in scientific research or literature, hence, detailed information about its properties and usage is limited. As with all chemicals, proper precautions should be taken while handling it due to potential hazards.

Check Digit Verification of cas no

The CAS Registry Mumber 1967-31-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,6 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1967-31:
(6*1)+(5*9)+(4*6)+(3*7)+(2*3)+(1*1)=103
103 % 10 = 3
So 1967-31-3 is a valid CAS Registry Number.

Functionalization in flexible porous solids: Effects on the pore opening and the host-guest interactions

Devic, Thomas,Horcajada, Patricia,Serre, Christian,Salles, Fabrice,Maurin, Guillaume,Moulin, Beatrice,Heurtaux, Daniela,Clet, Guillaume,Vimont, Alexandre,Greneche, Jean-Marc,Le Ouay, Benjamin,Moreau, Florian,Magnier, Emmanuel,Filinchuk, Yaroslav,Marrot, Jerome,Lavalley, Jean-Claude,Daturi, Marco,Ferey, Gerard

The synthesis on the gram scale and characterization of a series of flexible functionalized iron terephthalate MIL-53(Fe) type solids are reported. Chemical groups of various polarities, hydrophilicities, and acidities (-Cl, -Br, -CF3, -CH3, -NH2, -OH, -CO2H) were introduced through the aromatic linker, to systematically modify the pore surface. X-ray powder diffraction (XRPD), molecular simulations, thermogravimetric analyses, and in situ IR and 57Fe Moessbauer spectrometries indicate some similarities with the pristine MIL-53(Fe) solid, with the adoption of the narrow pore form for all solids in both the hydrated and dry forms. Combined XRPD and computational structure determinations allow concluding that the geometry of the pore opening is predominantly correlated with the intraframework interactions rather than the steric hindrance of the substituent. Only (MIL-53(Fe)-(CF3)2) exhibits a nitrogen accessible porosity (SBET ≈ 100 m2 g-1). The adsorption of some liquids leads to pore openings showing some very specific behaviors depending on the guest-MIL-53(Fe) framework interactions, which can be related to the energy difference between the narrow and large pore forms evaluated by molecular simulation.

Paragraph 0025; 0049-0052, (2021/03/11)

The invention provides a preparation method of an aromatic dicarboxylic acid derivative, wherein the preparation method comprises the following steps: step 1, carrying out a coupling reaction on dihalogenated aromatic hydrocarbon and metal cyanide at a temperature of 40-200 DEG C under metal catalysis in a solvent, and carrying out extraction layering concentration to obtain a dicyano compound after the reaction is finished; and step 2, carrying out a hydrolysis reaction on the obtained dicyanogen compound at the temperature of 60-200 DEG C under an acidic condition, and carrying out post-treatment to obtain the final product. According to the preparation method of the aromatic dicarboxylic acid derivative, dihalogenated aromatic hydrocarbon reacts with metal cyanide and then is hydrolyzedunder the acidic condition to obtain aromatic acid or the derivative thereof, and the preparation method has the remarkable advantages that the raw materials are cheap and easy to obtain, operation is easy and convenient, the yield is high, three wastes are easy to dispose, the product quality is high, and the substrate tolerance is good.

Halogen bonding in UiO-66 frameworks promotes superior chemical warfare agent simulant degradation

Kalaj, Mark,Momeni, Mohammad R.,Bentz, Kyle C.,Barcus, Kyle S.,Palomba, Joseph M.,Paesani, Francesco,Cohen, Seth M.

supporting information, p. 3481 - 3484 (2019/03/26)

Herein, a series of halogenated UiO-66 derivatives was synthesized and analyzed for the breakdown of the chemical warfare agent simulant dimethyl-4-nitrophenyl phosphate (DMNP) to analyze ligand effects. UiO-66-I degrades DMNP at a rate four times faster than the most active previously reported MOFs. MOF defects were quantified and ruled out as a cause for increased activity. Theoretical calculations suggest the enhanced activity of UiO-66-I originates from halogen bonding of the iodine atom to the phosphoester linkage allowing for more rapid hydrolysis of the P-O bond.

Tuning the hydrogenation activity of Pd NPs on Al-MIL-53 by linker modification

Zhang, Damin,Guan, Yejun,Hensen, Emiel J. M.,Xue, Teng,Wang, Yimeng

, p. 795 - 802 (2014/03/21)

The hydrogenation activity of 3 wt.% Pd nanoparticles supported on various mono-group (H, OCH3, NH2, Cl, and NO2) substituted Al-MIL-53 materials has been investigated. Substituents enhanced the dispersion of palladium nanoparticles on Al-MIL-53, leading to a narrow particle size distribution in the range of 2 to 4 nm. Pd nanoparticles on fresh catalysts were present as a mixture of Pd(ii) and Pd(0) with different ratios. These Pd species readily became metallic in a hydrogen flow even at room temperature. Their activities in hydrogenation of phenol and phenylacetylene are linked to the substituents on the aromatic ring of the framework. Catalysts with electron-donating groups (OCH3 and NH2) show much higher activity than those containing electron-withdrawing groups (Cl and NO2). This behavior might be explained by the hydrogen dissociation abilities of metallic Pd nanoparticles affected by the organic linkers.
