The alkaline hydrolysis of esters in aqueous-organic solvent mixtures. The effects of solvents and of the activity coefficients of reactants on the kinetics of the alkaline hydrolysis of methyl acetate in aqueous dioxan, aqueous dimethyl sulphoxide and aqueous diglyme (bis (2-methoxyethyl ) ether) mixtures as solvents.
… the rate constant for the alkaline hydrolysis of methyl acetate in various aqueous-organic solvent mixtures (dimethyl sulfoxide 0<x40.2, dioxane 0 <, x., < 0.2, methyl ethyl ketone 0<x<0.06 and diglyme, i. e. ether-bis (2-methyloxethyl) 0x<0.10) have been determined for the temperatures 15 0 C, 25 …

Optimisation of complex distillation colomn systems using rigorous models
… was investigated that looked at the synthesis of methyl acetate from acetic acid and methanol. The packed collocation model was used as a comparison with another investigation performed in literature (using equilibrium distillation models). Both showed comparable results, but still had significant …

Reaction calorimetry applied to kinetic problems. The design and construction of an isothermal calorimeter with heat compensation by the Peltier effect, and the application of the calorimeter in the study of reaction kinetics in solvent/water mixtures.
… been used to study the alkaline hydrolysis of methyl acetate in dimethylsulphoxide, and tetrahydrofuran - water mixtures at 15, 25 and 35 [degrees]C. The results of other investigations on similar reactions have been reviewed and an attempt has been made to correlate the electrostatic theories …

Design and characterization of zeolite supported cobalt carbonyl catalysts
… observed in the carbonylation of methanol were methyl acetate and an acetaldehyde dimethyl acetal. The supported cobalt catalyst displays greater activity than Co₂(CO)₈ in solution for the carbonylation reaction when conducted under similar conditions. In the Fischer-Tropsch process, selectivity …

In-situ spectroscopic studies of the mechanism of solid super-acid catalysed methanol carbonylation
… and loss of solid acidity due to undesired methyl acetate hydrolysis, alleviated by water addition and lower temperature operation. A mechanistic insight is provided using XPS, EXAFS and in-situ IR indicating the role of the organoRh and solid acid functionalities of activating CO and …

Asymmetric Synthesis of Homotropinone and Tropane Alkaloids using Enantiopure Sulfinimines and the Synthesis and Applications of Methanoprolines
… of the Weinreb amide enolate of N-methoxy-Nmethylacetamide to masked oxo sulfinimines (N-sulfinyl imines). Treatment of these Weinreb amides with Grignard reagents gave the N-sulfinyl ß-amino ketone ketals in 93- 95% yields without epimerization. Heating the acyclic ß-amino ketone ketals …
