Lignina, estructura y aplicaciones: métodos de despolimerización para la obtención de derivados aromáticos de interés industrial

Chávez-Sifontes, Marvin; Domine, Marcelo Eduardo (Executive Business School, 2013)

[ES] En este artículo se presentan datos significativos de las características estructurales de la lignina, los procesos de extracción y aislamiento a partir de la biomasa, y también las características de distintos tipos ...
Procesos Catalíticos Sostenibles para la Transformación de Derivados de Biomasa en Productos Químicos

Chávez Sifontes, Marvin Horacio (Universitat Politècnica de València, 2017-11-06)

Ligno-cellulosic biomass from agricultural and forest residues is an alternative to chemicals and fuels production, minimizing our dependence on fossil raw materials. However, nowadays the processes for the valorization ...
Synthesis of furan derivatives via cascade-type reactions catalyzed by solid acids

Chávez Sifontes, Marvin Horacio; Domine, Marcelo Eduardo; Valencia Valencia, Susana (Elsevier, 2015-11-15)

The 2-methylfuran (2-MF), easily obtained from furfural as a lignocellulosic biomass derivative, can beconverted in good yields (70%) into 5,5-bis(5-methyl-2-furyl)pentan-2-one by condensation in the pres-ence of mineral ...
Transformación catalítica de compuestos furánicos derivados de la biomasa en productos de interés industrial

Chávez Sifontes, Marvin Horacio (Universitat Politècnica de València, 2014-10-03)

[EN] The alkylation/condensation process of 2-methylfuran was studied using homogeneous catalyst, heterogeneous catalysts and olefins as alkylating agents. With the homogeneous catalyst (AlCl3) high conversions are obtained ...
Tuning zirconia-supported metal catalysts for selective one-step hydrogenation of levoglucosenone

Mazarío-Santa-Pau, Jaime; Parreño-Romero, Miriam; Concepción Heydorn, Patricia; Chávez-Sifontes, Marvin; Spanevello, Rolando A.; Comba, María B.; Suárez, Alejandra G.; Domine, Marcelo Eduardo (The Royal Society of Chemistry, 2019-09-07)

[EN] Levoglucosenone, directly produced from cellulose-containing residual biomass via pyrolysis treatments, is believed to be a promising bio-renewable platform for both fine and commodity chemicals. In this work, the ...
