Optimization of Acid Hydrolysis Process for the Preparation Cellulose Nanofibrils
(VBRI Press, 2019-02)
Cellulose nanofibrils can be obtained from microcrystalline cellulose by acid hydrolysis processes. Under optimum hydrolysis conditions is possible to obtain cellulose nanofibers with high surface / volume ratio, high ...
Microwave Assisted Synthesis of ethyl-quinolon-4-one-3-carboxylates and Hydrolysis to quinolon-4-one-3-carboxylic Acids
(Bentham Science Publishers, 2014-05)
A fast and efficient microwave assisted synthesis of several ethyl-quinolon-4-one-3-carboxylates and quinolon- 4-one-3-carboxylic acids has been developed. The 3-carboethoxy quinolones are easily obtained in a one-pot ...
Sensibilidad Paramétrica y Condiciones Seguras de Operación de la Hidrólisis del Anhídrido Acético en un Reactor Batch
(Centro de Informacion Tecnologica, 2016-01-01)
The results of a study on the parametric sensitivity of acetic acid production by hydrolysis of acetic anhydride, using acid homogeneous catalysis in a batch reactor, are presented. Dimensionless parameters of mass and ...
Effects of the enzymatic hydrolysis treatment on functional and antioxidant properties of quinoa protein acid-induced gels
(Elsevier Science, 2020-01)
Partial enzymatic hydrolysis is frequently used as strategy to improve the functional and nutritional properties of vegetable proteins. The aim of this work was to evaluate the hydrolysis of quinoa proteins, as well as the ...
Optimisation of microwave-assisted acid hydrolysis for the determination of seleno-amino acids bound to proteins in powdered milk, lyophilized milk and infant formula
(Academic Press Inc Elsevier Science, 2019-06)
Selenium (Se) is an essential element present in milk as seleno-amino acids and seleno-proteins. To perform an accurate seleno-amino acid analysis, a complete hydrolysis of proteins is necessary. Microwave-assisted acid ...

Evalua la hidrólisis del almidón de yuca al 30% p/v por el método de hidrólisis acida yenzimática. En el proceso de hidrólisis ácida se evaluó el efecto de la concentración del acidoclorhídrico de 1%, 3% y 5% sobre el ...
An energy-saving re-use strategy for the treatment of lignocellulosic biomass applied to the production of levulinc acid
(Elsevier, 2020-06)
A strategy for the re-use of spent liquors during the batch dilute acid treatment of lignocellulosic biomass was evaluated as an alternative to reduce the consumption of water and energy. Using the same spent liquor in the ...
Free-fatty acid profile obtained by enzymatic solvent-free hydrolysis of sunflower and soybean lecithins
(Elsevier, 2010-05-01)
The free-fatty acid profile of sunflower and soybean lecithins generated by enzymatic hydrolysis was determined by capillary gas chromatography using the internal standard method. This procedure involves the previous lipid ...
Diffusion and hydrolysis effects during water aging on an epoxy-anhydride system
(Elsevier, 2018-07)
Hydrothermal aging of an epoxy-anhydride network has been studied by means of gravimetric analysis, Fourier transform infrared spectroscopy (FTIR) and modulated differential scanning calorimetry (MDSC). The long-term aging ...
