Kinetics of autocatalytic acid hydrolysis of cellulose with crystalline and amorphous fractions
(SPRINGER, 2010)
The acid hydrolysis of cellulose with crystalline and amorphous fractions is analyzed on the basis of autocatalytic model with a positive feedback of acid production from the degraded biopolymer. In the condition of low ...
CELLULOSE NANOCRYSTALS FROM BACTERIAL CELLULOSE
(Soc Brasileira Quimica, 2015-11-01)
Bacterial cellulose produced from Gluconacetobacter xilinus was used to produce cellulose nanocrystals by sulfuric acid hydrolysis. Hydrolysis was performed with 64% sulfuric acid at 50 degrees C with the hydrolysis time ...

Ketalization of ketones to 1,3-dioxolanes and concurring self-aldolization catalyzed by an amorphous, hydrophilic SiO2-SO3H catalyst under microwave irradiation
(2018-08-01)
The amorphous, mesoporous SiO2-SO3H catalyst with a surface area of 115 m2 g-1 and 1.32 mmol H+ per g was very efficient for the protonation of ketones on a 10% (m/m) basis, and the catalyst-bound intermediates can be ...

Rendimento de polpa kraft após remoção parcial das hemiceluloses por auto-hidrólise em cavacos de Eucalyptus grandis x Eucalyptus urophylla e Eucalyptus grandis
(Universidade Estadual Paulista (Unesp), 2017-05-05)
A indústria papeleira vem focando em estudos atuais, alternativas para separar a madeira em seus componentes, celulose, hemiceluloses, lignina e extrativos, pois eles que restringem as diversas oportunidades da biorrefinaria ...
Development of a novel catalytic amyloid displaying a metal-dependent ATPase-like activity
(Elsevier B.V., 2017)
Amyloids are protein aggregates of highly regular structure that are involved in diverse pathologies such as Alzheimer's and Parkinson's disease. Recent evidence has shown that under certain conditions, small peptides can ...
