Recommanded Product: cis-Cyclohexane-1,2-dicarboxylic acid. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: cis-Cyclohexane-1,2-dicarboxylic acid, is researched, Molecular C8H12O4, CAS is 610-09-3, about The effects of cis-trans configuration of cyclohexane multi-carboxylic acids on colloidal forces in dispersions: steric, hydrophobic and bridging. Author is Chandramalar, A. V. M.; Lim, Y. Y.; Leong, Y. K..

The effects of cis- and trans-1,2-, trans-1,4-cyclohexanedicarboxylic acid, 95% cis-1,3,5-cyclohexane tricarboxylic acid and cis-1,2,3,4,5,6-cyclohexanehexacarboxylic acid on the yield stress-pH behavior of concentrated ZrO2 dispersions are reported. Adsorbed cis-1,2,3,4,5,6-cyclohexanehexacarboxylic acid imparts predominantly steric interactions. It forms a steric barrier keeping the interacting particles apart. Adsorbed cis- and trans-1,2 increase the maximum yield stress and this was attributed to a hydrophobic force resulting from the part of the cyclohexane ring sticking out into the solution which is devoid of charged or hydrophilic group. Adsorbed trans-1,4 increases the maximum yield stress by ≥3-fold and its configuration favors strong bridging interaction with an adjacent particle. Predominantly, cis-1,3,5 also increases the maximum yield stress but only by 60% at the same additive concentration This was attributed to a smaller degree of bridging.

As far as I know, this compound(610-09-3)Recommanded Product: cis-Cyclohexane-1,2-dicarboxylic acid can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.

Product Details of 37443-42-8. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: Methyl tetrahydrofuran-2-carboxylate, is researched, Molecular C6H10O3, CAS is 37443-42-8, about Selective hydrogenolysis of 2-furancarboxylic acid to 5-hydroxyvaleric acid derivatives over supported platinum catalysts. Author is Asano, Takehiro; Takagi, Hiroshi; Nakagawa, Yoshinao; Tamura, Masazumi; Tomishige, Keiichi.

The conversion of 2-furancarboxylic acid (FCA), which is produced by oxidation of furfural, to 5-hydroxyvaleric acid (5-HVA) and its ester/lactone derivatives with H2 was investigated. Monometallic Pt catalysts were effective, and other noble metals were not effective due to the formation of ring-hydrogenation products. Supports and solvents had a small effect on the performance; however, Pt/Al2O3 was the best catalyst and short chain alcs. such as methanol were better solvents. The optimum reaction temperature was about 373 K, and at higher temperature the catalyst was drastically deactivated by deposition of organic materials on the catalyst. The highest yield of target products (5-HVA, δ-valerolactone (DVL), and Me 5-hydroxyvalerate) was 62%, mainly obtained as Me 5-hydroxyvalerate (55% yield). The byproducts were mainly ring-hydrogenation compounds (tetrahydrofuran-2-carboxylic acid and its ester) and undetected ones (loss of carbon balance). The catalyst was gradually deactivated during reuses even at a reaction temperature of 373 K; however, the catalytic activity was recovered by calcination at 573 K. The reactions of various related substrates were carried out, and it was found that the O-C bond in the O-C=C structure (1,2,3-position of the furan ring) is dissociated before C=C hydrogenation while the presence and position of the carboxyl group (or methoxy carbonyl group) much affect the reactivity.

Author is Balapoor, Leila; Bikas, Rahman; Dargahi, Maryam.

A new dioxidomolybdenum(VI) complex, [MoO2(L)(CH3OH)] (1), was synthesized by the reaction of MoO3 with ONO-donor hydrazone ligand that was obtained from the condensation of benzolyacetone and furan-2-carbohydrazide in methanol. Both of the ligand and complex were characterized by elemental anal. and FTIR, NMR and UV-visible spectroscopic methods. The structure of complex was also determined by single crystal x-ray anal. Structural anal. showed that the Mo(VI) ion has a distorted octahedral geometry and the ligand is coordinated to the metal ion as dineg. ONO-donor ligand. The obtained molybdenum(VI) complex was used as catalyst in oxidation of benzyl alc. with H2O2 as a green oxidant. The effects of some parameters such as temperature, solvent and ratio of materials were also studied. Catalytic studies indicated that complex 1 can efficiently catalyze the oxidation of benzyl alc. but its activity and selectivity are considerably dependent on the reaction condition.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Condensation of aromatic aldehydes with glycine and acetylglycine》. Authors are Dakin, H. D..The article about the compound:cis-Cyclohexane-1,2-dicarboxylic acidcas:610-09-3,SMILESS:O=C([C@H]1[C@@H](C(O)=O)CCCC1)O).Recommanded Product: cis-Cyclohexane-1,2-dicarboxylic acid. Through the article, more information about this compound (cas:610-09-3) is conveyed.

The condensation referred to in the title is complicated by a competing reaction between CH2(NH2)CO2H and BzH, forming a non-acetylated derivative possibly of a type resembling a Schiff base. The 2 reactions are shown thus: (1) H2NCH2CO2H → AcNHCH2CO2H → MeC:N.C(:CHPh).CO.O → MeCONHC(:CHPh)CO2H, (2) HO2CCH2NH2 + BzH → HO2CCH2N:-CHPh (I) or O.CO.CH2.NH.CHPh. I may be called benzylideneglycine and was isolated and analyzed. Because the 2nd condensation product is a non-acetylated compound its formation can be largely suppressed by acetylating the glycine before the reaction. Correspondingly larger yields of the azlactone of α-acetamidocinnamic acid were obtained. Acetylation was most easily effected by warming glycine suspended in 3 parts of glacial AcOH with the theoretical amount of Ac2O until solution was obtained. A variety of aldehydes was used although the product from salicyl aldehyde was the most interesting. AcOC6H4CH:C.N:CMe.O.CO (II) → HOC3H4CH:C(NHAc)CO2H (III) → O.C6H4.CH:C(NHAc).CO (IV). II on treating with alkali and subsequent acidification forms the transient III which quickly passes over to IV. Detailed exptl. data are given.

COA of Formula: C6H10O3. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: Methyl tetrahydrofuran-2-carboxylate, is researched, Molecular C6H10O3, CAS is 37443-42-8, about Hydrogenolysis of tetrahydrofuran-2-carboxylic acid over tungsten-modified rhodium catalyst. Author is Asano, Takehiro; Nakagawa, Yoshinao; Tamura, Masazumi; Tomishige, Keiichi.

Catalysts for reduction of tetrahydrofuran-2-carboxylic acid (THFCA), which can be synthesized from furfural via oxidation and hydrogenation, were explored among the combinations of noble metal and reducible metal oxide supported on SiO2. Rh-WOx/SiO2 catalysts showed activity in C-O hydrogenolysis at 2-position of THFCA (to δ-valerolactone and 5-hydroxyvaleric acid) and higher yield ratio of these C-O hydrogenolysis products to carboxylic acid hydrogenation products than other bimetallic catalysts. The activity of Rh-WOx/SiO2 catalysts was highest at W/Rh = 0.25 mol/mol. X-ray diffraction, TPR, CO adsorption and XAFS characterizations showed that the Rh-WOx/SiO2 (W/Rh = 0.25) catalyst contained Rh metal particles with surface modification with isolated W2+ oxide species. The mechanism that hydride-like species formed on Rh atom attacks the C atom at the α-position (2-position) of adsorbed carboxylate on W atom is proposed based on the similar kinetics and similar catalyst structure to Rh-MOx/SiO2 (M = Re, Mo) which is known to be active in THFA hydrogenolysis to 1,5-pentanediol.
