A new synthetic methodology for pyridinic sucrose esters and their antibacterial effects against Gram-positive and Gram-negative strains
(Elsevier Ltd, 2020-02-19)
Described are the development of a new synthetic method using ultrasonic irradiation and sodium methoxide as catalyst for a series of pyridinic sucrose esters (py-SEs), derived from transesterification of sucrose with ...
Soaking and ozonolysis pretreatment of sugarcane straw for the production of fermentable sugars
(Elsevier B.V., 2019-11-28)
In the present study, sugarcane straw residue (SCS) is used to generate fermentable sugars. Impregnation in different media and ozonolysis were combined for SCS treatment. The best results were obtained for the basic medium ...
Natural sucrose esters: Perspectives on the chemical and physiological use of an under investigated chemical class of compounds
(Elsevier Ltd, 2020-06-20)
The present review describes the chemistry and physiological properties of the sucrose esters (SEs) obtained from natural or synthetic pathways, with emphasis on those that have aliphatic and phenylpropanoid substituents ...
Upgrading 1-butanol to unsaturated, carbonyl and aromatic compounds: A new synthesis approach to produce important organic building blocks
(Royal Society of Chemistry, 2020-04-21)
Unsaturated, carbonyl and aromatic products were obtained by reacting 1-butanol or a 1-butanol : methanol mixture with a copper mixed metal oxide catalyst in a fixed bed reactor. The selectivities observed, mostly for the ...
Enhancing the production of the fermentable sugars from sugarcane straw: A new approach to applying alkaline and ozonolysis pretreatments
(Elsevier Ltd, 2020-09-21)
The present study, sugarcane straw residue (SCS) was submitted to a combination of mild alkaline pretreatment and ozone cycles in a rotary reactor aiming to obtain fermentable sugars. The SCS exposed to short ozone cycles ...
