Controlling the selectivity to chemicals from lignin via catalytic fast pyrolysis was written by Ma, Zhiqiang;Troussard, Ekaterina;van Bokhoven, Jeroen A.. And the article was included in Applied Catalysis, A: General in 2012.HPLC of Formula: 3929-47-3 This article mentions the following:
The catalytic fast pyrolysis of alk. lignin to useful chems. was investigated using zeolite catalysts with different acidity and pore size. The catalyst played dual roles in this process. In its acid form, it catalytically converted the depolymerized intermediates into desirable and more stable products. This and their surface prevented repolymn. and coke formation. The yield of liquid and the selectivity to desired products can be controlled by tuning of the acidity and pore size of the catalyst. Using no catalyst yielded 40 weight% of liquid, which mainly consisted of 6 weight% (carbon yield) of phenols and 19 weight% (carbon yield) of phenol alkoxy species. The highest yield of phenol alkoxy species was obtained over H-ZSM5 of extremely low number of acid sites; liquid yield of 51 weight% and carbon yield of 24 weight%. The highest yield of liquid (75 weight%) was obtained over H-USY, which had the largest pore size and lowest Si/Al ratio, thus the largest number of acid sites among all the catalyst tested; the carbon yield of aromatic hydrocarbons was around 40 weight% at 650 °C. Depolymerized lignin products undergo consecutive reaction to form phenol alkoxy, phenols, and eventually aromatic hydrocarbons. In the experiment, the researchers used many compounds, for example, 3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3HPLC of Formula: 3929-47-3).
3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.HPLC of Formula: 3929-47-3
