Use of metal catalysts bearing Schiff base macrocycles for the ring opening polymerization (ROP) of cyclic esters [PDF]
, 2017 © 2017 by the authors. Schiff base macrocycles are emerging as useful scaffolds for binding two or more catalytic metals in close proximity. Such coordination chemistry allows for the evaluation of potentially beneficial catalytic cooperative effects. In

Chemistry – A European Journal, 2015 AbstractThe introduction of ester groups on the 5‐ and 15‐meso positions of corroles stabilizes them against oxidation and induces a redshift of their absorption and emission spectra. These effects are studied through the photophysical and electrochemical characterization of up to 16 different 5,15‐diester corroles, in which the third meso position is ...

Impact of Stabilization Method and Filtration Step on the Ester Profile of “Brandy de Jerez”
Applied Sciences, 2023 Brandy stabilization is an important step aimed at decanting the suspended organic and inorganic particles that may cause undesirable turbidity (cloudiness or haze) in brandies, affecting the physico-chemical stability, the organoleptic characteristics ...

Descriptors for terpene esters from chromatographic and partition measurements: Estimation of human odor detection thresholds [PDF]
, 2020 We have used gas chromatographic retention data together with other data to obtain Abraham descriptors for 30 terpene esters. These include the air-water partition coefficient, as log Kw, for which no experimental values are available for any terpene ...

Cu/ZrO2 Catalyst Modified with Y2O3 for Effective and Stable Dehydration of Glycerol to Acetol
MoleculesGlycerol is a main by-product of biodiesel production, and its further processing is essential for the biorefinery. In this paper, a highly active and stable catalyst for the catalytic dehydration of glycerol to acetol is obtained by modifying a Cu-Zr ...
