TL;DR: In this article, the rate of dehydrogenation of isopropyl alcohol over a zinc oxide catalyst has been measured at 158-195 °C, at an isoprophyl alcohol pressure range of 003-100 torr.

TL;DR: In this article, the authors proposed a process for reducing the amount of ultraviolet light absorbing ketone impurities and/or aldehyde impurities in a fluid mixture containing an alcohol, in addition to other impurities.
Abstract: The invention provides a process for the purification of alcohols, particularly for the purification of isopropyl alcohol A invention provides a process for reducing the amount of ultraviolet light absorbing ketone impurities and/or aldehyde impurities in a fluid mixture containing an alcohol in addition to ketone impurities and/or aldehyde impurities, which comprises reacting a fluid mixture containing an alcohol in addition to ketone impurities and/or aldehyde impurities, with a sufficient amount of a reducing agent, under conditions wherein the reducing agent is preferentially more reactive with the ketone impurities and/or aldehyde impurities than the alcohol to thereby form a reaction product; and then recovering a recovered alcohol product from the reaction product

TL;DR: In this paper, the effect of substitution has been analyzed by linear free energy relations and the variation in the susceptibilities of the systems to polar substituent effects with the medium are examined.
Abstract: The rate coefficients for the reaction with diazodiphenylmethane in methanol, ethanol, isopropyl alcohol, t-butyl alcohol, 2-methoxyethanol, 2-n-butoxyethanol, and ethyl acetate at 30° and the pKa values in 80% 2-n-butoxyethanol–water of a series of 9-substituted 10-anthroic and 8-substituted 1-naphthoic acids have been determined. The effect of substitution has been analyzed by linear free energy relations. The variation in the susceptibilities of the systems to polar substituent effects with the medium are examined. The occurrence of reversed dipolar substituent effects in the reactions of the 1,8-naphthoic acids is detected. The implications of the results for the inductive and field effect models for the transmission of polar effects are discussed.
