On October 31, 2020, He, Liao; Sang, Yimin; Yu, Wang; Li, Wanxin; Jiao, Yuhai; Ma, Fujun; Li, FasHeng; Liu, Yuqin; Gu, Qingbao published an article.HPLC of Formula: 96-76-4 The title of the article was Polymerization and Carbonization Behaviors of 2-Methylnaphthalene in Contaminated Soil During Thermal Desorption. And the article contained the following:
Despite the important niche and broad applicability of thermal remediation (TD), little work has been done to discuss chem. reactions of methylnaphthalene contaminated soil. The 2-methylnaphthalene desorption amount (MDA) of TD is studied here under different conditions, and the carbonation (chem. polymerized or condensed) behavior of 2-methylnaphthalene is explained by analyzing the changes of soil organic carbons (SOCs), off-gas products, and surface chem. properties. It indicates that the influence sequence of MDA from high to low is heating time, heating temperatures, and flow rates of carrier gas. MDA increases steadily with the increase of temperatures (200-300°C) but decreases slightly after 300°C; the reason may be the chem. conversion of 2-methylnaphthalene. GC-MS anal. of off-gas confirms that partial 2-methylnaphthalene is polymerized to form 2-methylbenzo[b]thiophene and 2,4-di-tert-butylpheno at 400°C, which is the first step of carbonization process. The XPS results of soil indicate that the C content decreases, but C-(C, H) chem. structure increases, indicating that new carbonaceous substances are generated. A layer of “char” is seen by scanning electron microscope to be left on the surface of the soil particles. As the temperature increases (200-400°C), the SOCs generally decreases from 1.14 to 0.82%, which is the result of the equilibrium between SOCs pyrolysis and 2-methylnaphthalene carbonization. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).HPLC of Formula: 96-76-4
