Thermal behavior of the maleic anhydride modified poly(3-hydroxybutyrate)
(Springer, 2007-03-01)
Poly(3-hydroxybutyrate), PHB has been structurally modified through reaction with maleic anhydride, MA. Transesterification reaction was carried out fixing the PHB and MA and besides time and temperature the concentration ...

Sunflower oil methanolisys and glycerol ketalisation: Stepwise production of biofuels and additives with 3-methylimidazolium hydrogensulphate as catalyst
(2016-01-01)
The ionic liquid 3-methylimidazolium hydrogensulfate is soluble within the glycerol phase that it creates, after catalyzing the transesterification of sunflower oil to fatty acids methyl esters with methanol. Separation ...
Comparison of extraction and transesterification methods on the determination of the fatty acid contents of three Brazilian seaweed species
(Sociedade Brasileira de Farmacognosia, 2012)
Seaweeds are photosynthetic organisms important to their ecosystem and constitute a source of compounds with several different applications in the pharmaceutical, cosmetic and biotechnology industries, such as triacylglycerols, ...
Clean transesterification of β-ketoesters catalyzed by hybrid silica sol-gel
(Elsevier, 2006)
A mild chemoselective and suitable transesterification on b-ketoesters has been developed employing functionalized silica sol-gel as heterogeneous catalyst which can be reused several times without appreciable loss of ...
Significant effects of the anion on the catalytic behaviour of sulfonic acid-functionalized ionic liquids in transesterification reactions – A combined electrochemical/catalytic study
(Elsevier, 2021-08)
This work studies the strong influence of the counterion on the performance of ionic liquids (ILs) with sulfonic acid-functionalized butyl-imidazolic bases as homogeneous acid catalysts. Through a voltammetric analysis, ...
