Reaction parameters effect on hydrothermal liquefaction of castor (Ricinus Communis) residue for energy and valuable hydrocarbons recovery was written by Kaur, Ravneet;Gera, Poonam;Jha, Mithilesh Kumar;Bhaskar, Thallada. And the article was included in Renewable Energy in 2019.Safety of Pyridin-4-ol This article mentions the following:
Castor plant (Ricinus communis) is a fast growing, perennial shrub also known as wonder tree from Euphorbiaceae family. India ranks globally first with production of 87% of the castor seed, while second and third largest producer countries, China and Brazil produced 5% and 1%, resp. Hydrothermal liquefaction (HTL) is one of the most promising thermochem. conversion process used to convert wet/high moisture biomass to biofuels and value-added hydrocarbons. HTL of castor residue (stem and leaves) was performed at 260, 280, 300 °C and 15, 30, 60, 90 min. Investigations on the effect of temperature and residence time on distribution of products (bio-oil, bio-char) indicated the maximum Total Bio-oil (TBO) yield of c.a. 15.8 wt% was obtained at 300 °C at 60 min. The major compounds observed by GC-MS were phenols and their derivatives, aromatic hydrocarbons, N-containing compounds, acids. In addition, the recovery of carbon and corresponding energy recovery with respect to castor residue indicated that the carbon and energy recovery for bio-oil 1 were 24.23% and 31.08% resp. An increase in the carbon and decrease of oxygen content in bio-oil (BO) demonstrates that the castor residue can be used as a potential feedstock for bioenergy applications. In the experiment, the researchers used many compounds, for example, Pyridin-4-ol (cas: 626-64-2Safety of Pyridin-4-ol).
Pyridin-4-ol (cas: 626-64-2) belongs to pyridine derivatives. Pyridine’s the lone pair does not contribute to the aromatic system but importantly influences the chemical properties of pyridine, as it easily supports bond formation via an electrophilic attack. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Safety of Pyridin-4-ol
