Difference in chemical composition of supercritical methanolysis products between two lignites was written by Chen, Bo;Wei, Xian-Yong;Zong, Zhi-Min;Yang, Zhu-Sheng;Qing, Yu;Liu, Chang. And the article was included in Applied Energy in 2011.Electric Literature of C12H22O4 This article mentions the following:
Dehydrated Xilinhaote lignite (XL) and Huolinguole lignite (HL) were depolymerized in supercritical methanol at 310 °C and the resulting soluble reaction mixtures were analyzed with GC/MS. The results show that the GC/MS-detectable species can be classified into hydroxybenzenes (HBs), esters, ketones, alkanols, arenes, methoxybenzene, alkanes, alkenes, nitrogen-containing organic compounds, sulfur-containing organic compounds, aldehydes and other compounds However, the difference in the product yield from different coals is significant. The most abundant products are HBs from XL and esters from HL. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Electric Literature of C12H22O4).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Electric Literature of C12H22O4
