Estolide esterBiolubricantBiodieselCholine carboxylateIonic liquidMolecular distillationA new three step process has been developed and optimized in order to demonstrate that is possible to get complete conversion of free fatty acids (FFA) into estolide esters (biolubricant), biodiesel and choline ...
Acid-catalyzed conversion of 2-O-(2-hydroxypropyl)-d-glucose derivatives into 1,2-O-(1-methyl-1,2-ethanediyl)-d-glucose acetals. Studies related to O-(2-hy... Acid-catalyzed conversion of 2-O-(2-hydroxypropyl)-d-glucose derivatives into 1,2-O-(1-methyl-1,2-ethanediyl)-d-glucose ...
In an ester like methyl formate, xylose can be converted to furfural selectively and efficiently. Approximately 70% yields of furfural were achieved at 150 °C in a very short time, and more importantly, methyl formate is highly volatile (boiling point: 32 °C). It can be distilled from ...
Figure 1. Chemical structure of gallic acid (a) and its derivatives: gallic acid methyl ester (b), (-)-epigallocatechin gallate (c), and hydrolysable tannin (d). Currently, in addition to its strong anti-oxidant activity, gallic acid (GA) is also attributed with anti-cancer, anti-HIV,...
(97% of ester product) under conditions of 90°C for 2h using 4wt% sulphated titania with 20:1 of methanol to FFA molar ratio. Besides,TiO2/SO42−showed higher resistivity to water as compared to sulphuric acid whereby the reaction rate was reduced in the presence of water. In the ...
environmental conversion to microplastics, and impact on microbes, algae, phytoplankton, zooplankton, annelids, mollusk and fish. Polylactic acid is a low weight semi-crystalline bioplastic used in agriculture, medicine, packaging and textile. Polylactic acid is one of the most widely used biopolymers...
Lithocholic acid can be purified by conversion to the rather insoluble Na or K salt by addition of the equivalent amount of aqueous NaOH or KOH, filtering off the alkali salt, washing it with ice cold H2O, dissolving it in the least volume of boiling H2O, acidifying with the dilute HCl (...
