Effects of the water quantity on the solventless TEOS hydrolysis under ultrasound stimulation
(Kluwer Academic Publ, 2000-01-01)
The acid hydrolysis under ultrasound stimulation of solventless tetraethoxysilane(TEOS)-water mixtures was studied at 40 degrees C, by means of a heat flux calorimetric method, as a function of the initial water/TEOS molar ...
Hydrolysis of ginger bagasse starch in subcritical water and carbon dioxide
(Amer Chemical SocWashingtonEUA, 2004)
Kinetics of autocatalytic acid hydrolysis of cellulose with crystalline and amorphous fractions
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 ...
Solid-state hydrolysis of postconsumer polyethylene terephthalate after plasma treatment
Plasma treatments were applied on the surface of postconsumer polyethylene terephthalate (PET) bottles to increase their wettability and hasten the subsequent hydrolysis process. Sixty-four treatments were tested by varying ...
A kinetic model for the ultrasound catalyzed hydrolysis of solventless TEOS-water mixtures and the role of the initial additions of ethanol
(Kluwer Academic Publ, 1996-01-01)
The acid and ultrasound catalyzed hydrolysis of solventless TEOS-water mixtures are studied, as a function of the initial additions of ethanol to the mixtures, by means of flux calorimetry measurements. A device was specially ...
Water hyacinth second-generation ethanol production: a mitigation alternative for an environmental problem
Natural fibers are very abundant, especially those derived from water plant as water hyacinth. The water hyacinth, which is rich in cellulosic fiber content, has a great ability to adapt itself to harsh conditions and at ...
Formation and decomposition of N-alkyinaphthalimides: experimental evidences and ab initio description of the reaction pathways
The kinetics of hydrolysis of 1,8-N-butyl-naphthalimide (1,8-NBN) to 1,8-N-butyl-naphthalamide (1,8-NBAmide) and of 2,3-N-butyl-naphthalimide (2,3-NBN) to 2,3-N-butyl-naphthalamide (2,3-NBAmide), as well as the formation ...
Optimization of the enzymatic hydrolysis of chicken meat using response surface methodology
(Blackwell PublishingOxfordInglaterra, 2008)
Flavor release by enzymatic hydrolysis of starch samples containing vanillin-amylose inclusion complexes
(Elsevier Science, 2014-05)
Hylon VII is a high amylose corn starch which has excellent gelling properties, and its behavior as flavor encapsulant is relevant to the food industry because its ability to regulate a swelling-controlled release in aqueous ...
Biochemical characterization and enzymatic hydrolysis of different commercial soybean protein isolates
