Functionalization of a liquid natural rubber by iron‐mediated radical chloro‐nitration and its thermal decomposition
This study presents the functionalization of liquid natural rubber (LNR) by iron‐mediated radical chloro‐nitration over the LNR backbone, resulting in a chloro‐nitro compound of liquid natural rubber (Cl‐N‐LNR). The chloro‐nitration was prepared by a reaction of LNR with iron(III) nitrate nonahydrate and iron(III) chloride in an organic solvent. The structure of the obtained product was confirmed by using Fourier‐transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1H NMR), and carbon‐13 nuclear magnetic resonance (13C NMR), which showed the existence of chloro‐nitro groups in the Cl‐N‐LNR chain. The degree of functionalization with a nitro group is 13.4% mol units of Cl‐N‐LNR. The thermal degradation was determined by the thermogravimetric analysis (TGA) method. As a result, the kinetic parameters for the degradation of Cl‐N‐LNR were calculated in the range from 40 to 330 °C. The half‐life of Cl‐N‐LNR was found to be about 33.0 years.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
