Synthesis, characterization and thermal decomposition mechanism of rare earth complexes with 5-chloro-2-methoxybenzoic acid and 1,10-phenanthroline was written by Zhang, Jie;Wang, Juan-Fen;Zhang, Jian-Jun. And the article was included in Wuli Huaxue Xuebao in 2012.Reference of 3438-16-2 This article mentions the following:
Three rare earth complexes of [Ln(5-Cl-2MOBA)3phen]2 (Ln = Nd(1), Eu(2), Ho(3); 5-Cl-2MOBA: 5-chloro-2-methoxybenzoate; phen: 1,10-phenanthroline) were synthesized and characterized by elemental anal., TG-differential TG-DSC (TG-DTG-DSC), IR spectra, UV spectra, and molar conductance techniques. The fluorescence spectra showed that complex 2 emitted a characteristic fluorescence of the Eu3+ ions. The thermal properties are discussed by TG – DSC / FTIR (TG-DSC/FTIR) techniques. And the three-dimensional IR accumulation spectra for the three complexes were also analyzed. In the experiment, the researchers used many compounds, for example, 5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2Reference of 3438-16-2).
5-Chloro-2-methoxybenzoic acid (cas: 3438-16-2) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Reference of 3438-16-2
