And the article was included in Journal of Chemical & Engineering Data in 2010.Name: 5-Chloro-2-methoxybenzoic acid This article mentions the following:
The synthesis and structure determination of the Sm(III) complex with 1,10-phenanthroline (phen) and 5-chloro-2-methoxybenzoate (5-Cl-2-MOBA) are reported. The crystal and mol. structure of the complex, as well as its mol. formula and composition [Sm(5-Cl-2-MOBA)3phen]2, were determined by single-crystal x-ray diffraction, elemental analyses, and IR and thermogravimetric/differential thermogravimetric (TG-DTG) measurements. Meanwhile, the molar conductance and the UV spectra of the complex were measured and depicted. The crystal of the complex belongs to the triclinic crystal system, space group P1虆 with a 10.729(2), b 13.0971(18), c 13.5925(19) 脜, 伪 64.376(5), 尾 84.571(6), 纬 87.733(7)掳, Z = 1, dc = 1.719 t m-3, 渭 = 2.006 mm-1, and F(000) = 882. Each Sm(III) ion in the crystal is nine-coordinate with a distorted monocapped square antiprismatic conformation. The Sm(III) ion in the complex is coordinated by two O atoms of one chelating bidentate carboxylate group, five O atoms of two bridging bidentate, and two bridging-chelating tridentate carboxylate groups and two N atoms of one 1,10-phenanthroline mol. The thermal decomposition of [Sm(5-Cl-2-MOBA)3phen]2 can be divided into three stages. By the Malek method, SB(m,n) was defined as the kinetic model of the 1st-step thermal decomposition The activation energy E of this step is 183.63 kJ mol-1, and the pre-exponential factor ln A is 39.59. The thermodn. parameters 螖G鈮?/sup>, 螖H鈮?/sup>, and 螖S鈮?/sup> of activation at the peak temperature were also calculated In the experiment, the researchers used many compounds, for example, 5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2Name: 5-Chloro-2-methoxybenzoic acid).
5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Name: 5-Chloro-2-methoxybenzoic acid
