The kinetics of propylene oxide reaction with certain alkylamino alcohols in the presence of basic catalysts

Abstract

Rate constants for direct reactions of propylene oxide with certain aminoisopropanols in the presence of basic catalysts were studied at a temperature of 363–383 K. This reaction was found to be of the first order in propylene oxide, amino alcohol and catalyst. The observed kinetics are consistent with a termolecular mechanism.

Glycerol Electrocatalytic Reduction Using an Activated Carbon Composite Electrode: Understanding the Reaction Mechanisms and an Optimization Study

“…Zhang et al (2016) successfully produced 1-ethoxy-2-propanol by alcoholysis of propylene oxide and ethanol in the presence of catalyst whilst Chitwood and Freure (1946) acquired it even without any catalyst. In great support from the later work, 1-ethoxy-2propanol was indirectly generated through this reaction during the sample preparation and GC-MS characterization that incriminated ethanol as the solvent (Chitwood and Freure, 1946;Ślipko and Chlebicki, 1981). During the sample preparation, sodium hydroxide (NaOH) was used to precipitate out the sodium sulfate electrolyte from the taken sample.…”

Solvent Screening and Process Optimization for Separating Propylene Oxide from Direct Propylene Epoxidation with H2 and O2

“…According to the “like dissolves like” rule, the polar solvents having high PO solubility are preferred. Notably, the polar alcohol, acid, and phenol solvents could react with PO due to the existence of active hydrogen atoms, which are not suitable. In this work, solvent screening was carried out among 15 types of polar compounds based on ethers, ketones, esters, and aromatics, which have no reaction with inlet components.…”
