Biocatalytic preparation of dichloropropyl acrylates. Application to the synthesis of poly(dichloropropyl acrylates)
Yara Varón, Edinson; Eras i Joli, Jordi; Torres i Grifo, Mercè; Balcells Fluvià, Mercè; Villorbina Noguera, Gemma; Canela i Garayoa, Ramon (Elsevier, 2013)The synthesis of dichloropropyl acrylates from dichloropropyl dodecanoates through a transesterification process using diverse commercial lipases and whole cells (fungal resting cells) is presented. The synthesis was carried ... -
Characterisation of phenolic compounds in processed fibres from the juice industry
Delpino Rius, Antoni; Eras i Joli, Jordi; Vilaró, Francisca; Cubero, Miguel Ángel; Balcells Fluvià, Mercè; Canela i Garayoa, Ramon (Elsevier, 2015)The content of phenolic compounds was determined in nine industrially processed fibres derived from the juice industry. Apple, peach, and pear as non-citrus fruit fibres were examined, as well as orange peel and flesh, ... -
Combining AlCl3·6H2O and an ionic liquid to prepare chlorohydrin esters from glycerol
Villorbina Noguera, Gemma; Tomàs, Albert; Escribà i Gelonch, Marc; Oromí Farrús, Mireia; Eras i Joli, Jordi; Balcells Fluvià, Mercè; Canela i Garayoa, Ramon (Elsevier, 2009)We describe here the first example in which glycerol has been transformed into chlorohydrin esters using an ionic liquid and hydrated aluminium chloride. The method avoids using Crown-18 ether, which was needed to obtain ... -
Combining regio- and enantioselectivity of lipases for the preparation of (R)-4-chloro-2-butanol
Méndez, Jonh Jairo; Oromí Farrús, Mireia; Cervero, Maria; Balcells Fluvià, Mercè; Torres i Grifo, Mercè; Canela i Garayoa, Ramon (Wiley, 2007)Preparation of 98% ee (R)-4-chloro-2-butanol was carried out by the enzymatic hydrolysis of chlorohydrin esters, using fungal resting cells and commercial enzymes. Hydrolyzes were carried out using lipases from Candida ... -
Entirely solvent-free biocatalytic synthesis of solketal fatty esters from soybean seeds
Torregrosa García, Rubén; Yara Varón, Edinson; Balcells Fluvià, Mercè; Torres i Grifo, Mercè; Canela i Garayoa, Ramon (Académie des Sciences; Elsevier, 2016)Solvent-free reactions are the systems of choice in green chemistry. In addition to contributing to lowering the environmental impact of chemical processes, solvent-free systems can reduce production costs, reaction times, ... -
Lipase activity and enantioselectivity of whole cells from a wild-type Aspergillius flavus strain
Solarte Orozco, Carmen Eugenia; Yara Varón, Edinson; Eras i Joli, Jordi; Torres i Grifo, Mercè; Balcells Fluvià, Mercè; Canela i Garayoa, Ramon (Elsevier, 2014)This study reports the high enantiomeric preference of whole cell lipase from Aspergillus flavus wild-type that allows the preparation of a chiral secondary alcohol. Whole cells prepared from a wild-type Aspergillus flavus ... -
Recycling Rhizopus oryzae resting cells as biocatalyst to prepare near eutectic palmitic-stearic acid mixtures from non-edible fat
Gallart-Sirvent, Pau; Yara Varón, Edinson; Villorbina Noguera, Gemma; Balcells Fluvià, Mercè; Sala i Martí, Núria; Canela i Garayoa, Ramon (Elsevier, 2016)Here we studied non-edible fat waste as a starting material to prepare eutectic mixtures of biomaterials. Initially, the fat was hydrolyzed using water and R. oryzae resting cells. The hydrolysis was performed in organic ... -
Sustainable Synthesis of Omega-3 Fatty Acid Ethyl Esters from Monkfish Liver Oil
Aguilera-Oviedo, Johanna; Yara Varón, Edinson; Torres i Grifo, Mercè; Canela i Garayoa, Ramon; Balcells Fluvià, Mercè (MDPI, 2021-01-13)The search for economic and sustainable sources of polyunsaturated fatty acids (PUFAs) within the framework of the circular economy is encouraged by their proven beneficial effects on health. The extraction of monkfish ... -
Synthesis of poly(ethyl acrylate-co-allyl acrylates) from acrylate mixtures prepared by a continuous solvent-free enzymatic process
Yara Varón, Edinson; Eras i Joli, Jordi; Balcells Fluvià, Mercè; Torres i Grifo, Mercè; Canela i Garayoa, Ramon (Royal Society of Chemistry, 2012)A miniaturized, packed-bed, continuous-flow reactor to carry out the enzymatic interesterification of ethyl acrylate with diverse allyl aliphatic esters is described. CALB (lipase B from Candida antarctica immobilized on ...
