Acetylated starch and inulin as encapsulating agents of gallic acid and their release behaviour in a hydrophilic system
Abstract Gallic acid (GA) was encapsulated with native starch (NS), native inulin (NIn), acetylated starch (AS) or acetylated inulin (AIn) (two substitution degrees each) by spray-drying, and a 2 2… Expand
A theoretical study on the relationship between nucleophilicity and ionization potentials in solution phase
In this paper we describe a method to obtain estimates of the relative nucleophilicity for a series of neutral and charged electron donors from their solution phase ionization potential (Is). The… Expand
Concerted pyridinolysis of aryl 2,4,6-trinitrophenyl carbonates.
The Brønsted plots for the title reactions are linear with slopes of 0.53-0.56. The magnitude of the slopes and the fact that there are no breaks at the predicted pK(a) for stepwise mechanisms… Expand
Influence of the ionic liquid on the rate and the mechanism of reaction of p-nitrophenyl acetate with secondary alicyclic amines
The reaction of p-nitrophenyl acetate (1) with piperidine was studied in nine organic solvents and in nine ionic liquids. The aminolysis of 1 by four different secondary amines was also studied in… Expand
Supercritical fluid extraction and characterisation of oil from hazelnut
Hazelnut (Corylus avellana L.) oil was extracted with compressed carbon dioxide in the temperature range of 308—321 K and in the pressure range of 18—23.4 MPa. In addition the influence of the… Expand
Alpha‐tocopherol microspheres with cross‐linked and acetylated inulin and their release profile in a hydrophilic model
Alpha-tocopherol (AT) was encapsulated with native (NIn), acetylated (AIn) or cross-linked (CIn) inulin (two degrees each) by spray-drying. A face central composite experimental design for each… Expand

Herein, the reactivity and selectivity of the reaction of O,O-diethyl 4-nitrophenyl phosphate triester (Paraxon, 1) with piperidine in ionic liquids (ILs), three conventional organic solvents (COS),… Expand
A fully conjugated TTF-π-TCAQ system: synthesis, structure, and electronic properties.
The synthesis of the first fully conjugated tetrathiafulvalene-tetracyano-p-quinodimethane ((TTF)-TCNQ)-type system has been carried out by means of a Julia-Kocienski olefination reaction. In… Expand
Ionic liquids: anion effect on the reaction of O,O-diethyl O-(2,4-dinitrophenyl) phosphate triester with piperidine
The reactions of O,O-diethyl 2,4-dinitrophenylphosphate triester (1) with piperidine in ionic liquids and four conventional organic solvents (COS) were subjected to kinetic and product studies.… Expand
