Efficient Continuous Production of the Biofuel Additive 5-(t-Butoxymethyl) Furfural from 5-Hydroxymethylfurfural
(Wiley VCH Verlag, 2019-11)
The catalytic etherification of 5-hydroxymethylfurfural (HMF) with t-butanol to a biofuel additive 5-(t-butoxymethyl) furfural (t-BMF) is studied by screening 27 heterogeneous protic and/or Lewis acids. Preyssler heteropolyacid ...
Effect of storage time and temperature on the physicochemical and sensory characteristics of commercial apricot jam
Storage conditions are important factors for jam quality. The objective of this study was to monitor the
physicochemical stability and sensorial profile of apricot jam during storage for 60 days at 5 C, 25 C and
37 ...
Dehydration of d-fructose to 5-hydroxymethyl-2-furfural in DMSO using a hydrophilic sulfonated silica catalyst in a process promoted by microwave irradiation
(2021-12-01)
SiO2-SO3H, with a surface area of 115 m2/g, pore volumes of 0.38 cm3g−1 and 1.32 mmol H+/g, was used as a 10% w/w catalyst for the preparation of 5-hydroxymethyl-2-furfural (HMF) from fructose. A conversion of 100% was ...
Antioxidant and anti-glycation potential of green pepper (Piper nigrum): Optimization of β-cyclodextrin-based extraction by response surface methodology
(Elsevier, 2020-06)
Green pepper (Piper nigrum) presents high levels of functional compounds, with antioxidant and anti-glycation properties. Thus, the optimization of the β-cyclodextrin-based extraction of functional compounds from green ...
Clean catalytic oxidation for derivatization of key biobased platform chemicals: Ethanol, glycerol, and hydroxymethyl furfural
(American Chemical Society, 2019-07)
There has been a growing interest in the last decades in technologies that transform biomass-derived feedstock into renewable chemicals. A group of target molecules derived from biomass as key intermediates between raw ...
