A combined experimental and computational study of the esterification reaction of glycerol with acetic acid
(Springer Heidelberg, 2014-03)
This work describes theoretical and experimental studies on glycerol esterification to obtain acetins focusing on the obtained isomers. The reaction of glycerol with acetic acid was carried out on Amberlyst 36 wet. Density ...
Kinetic study of fuel bio-additive synthesis from glycerol esterification with acetic acid over acid polymeric resin as catalyst
(Elsevier, 2020-03)
The increase of remnant of glycerol from biodiesel production results in the need to develop valorization strategies for this low-cost by-product. In this context, bio-additives synthesis from glycerol such as acetylglycerides ...
Bioadditives synthesis from selective glycerol esterification over acidic ion exchange resin as catalyst
(Elsevier Ltd, 2018-04)
In this work, fuel bioadditives production from glycerol esterification with acetic acid was performed over acidic ion exchange resin as acid catalyst in a batch reactor. The influence of several parameters such as ...
Enzymatic synthesis of monoglycerides by esterification reaction using Penicillium camembertii lipase immobilized on epoxy SiO(2)-PVA composite
(ELSEVIER SCIENCE BV, 2010)
Glycerol-fatty acid esterification has been conducted with lipase from Penicillium camembertii lipase immobilized on epoxy SiO(2)-PVA in solvent-free media, with the major product being 1-monoglyceride, a useful food ...
H3PW12O40 (HPA), an Efficient and Reusable Catalyst for Biodiesel Production Related Reactions. Esterification of Oleic Acid and Etherification of Glycerol
(Sociedade Brasileira de Química, 2011-03)
In esterification of oleic acid with methanol at 25 °C HPA displayed the highest activity. Moreover the HPA could be reused after being transformed into its cesium salt. In the reaction of etherification of glycerol HPA ...
Valorization of glycerol through the enzymatic synthesis of acylglycerides with high nutritional value
(Molecular Diversity Preservation International, 2020-01-14)
The production of specific acylglycerides from the selective esterification of glycerol is an attractive alternative for the valorization of this by-product of the biodiesel industry. In this way, products with high added ...
Synthesis of bioadditives of fuels from biodiesel-derived glycerol by esterification with acetic acid on solid catalysts
(Taylor & Francis, 2017-06)
In this paper, glycerol esterification with acetic acid was studied on several solid acid catalysts: Al2O3, Al-MCM-41, HPA/SiO2, HBEA, Amberlyst-15 and Amberlyst-36 with the aim of determining the reaction conditions and ...
Relationship between structure and properties of modified potato starch biodegradable films
(John Wiley & Sons Inc, 2006-09)
Potato starch was gelatinized in the presence of water and varying amounts of glycerol at 90°C. Starch/ glycerol films were prepared by casting with water. The addition of glycerol produces a decrease in the crystallinity ...
Esterificação catalítica de ácido acético e glicerol para a produção de aditivos de combustível
(Universidade Federal de Santa MariaBrasilEngenharia QuímicaUFSMPrograma de Pós-Graduação em Engenharia QuímicaCentro de Tecnologia, 2022-09-02)
Biodiesel production through the transesterification route is on the rise, as a result, glycerol, a low-cost by-product of biodiesel, has become more saturated in the international market. A potential solution to this ...
Catalytic and molecular insights of the esterification of ibuprofen and ketoprofen with glycerol
(Elsevier, 2021-08)
The esterification of rac-ibuprofen and rac-ketoprofen with glycerol catalyzed with the commercial biocatalyst Novozym® 435 was investigated at 45 °C with various profen: glycerol molar ratios using 2-propanol as co-solvent ...
