TL;DR: In this article, the decomposition of isopropyl alcohol was chosen as a probe reaction of acid-base property of molybdena-alumina catalyst and the catalytic kinetics were examined on the oxidized catalyst.
Abstract: The decomposition of isopropyl alcohol was chosen as a probe reaction of acid-base property of molybdena-alumina catalyst. The catalytic kinetics was examined on the oxidized catalyst. The kinetics of the dehydration (yielding propene) and the dehydrogenation (yielding acetone) obeyed the Langmuir-Hinshelwood mechanism in which the rate determining step is the desorption of water for the former and the sur face reaction for the latter, respectively. The effect of varying the extent of reduction of the catalyst was also studied. The trend of variation with the reduction was fairly consistent with the surface chemistry of the catalyst.

TL;DR: A producing method of phosphoric acid applied in medical treatment comprises dissolving sodium hydroxide in n-propyl alcohol, isopropyl alcohol or mixtures thereof, dissolving the pheophorbide a in a solvent miscible with the solution of the sodium hyroxide solvent.
Abstract: A producing method of phosphoric a applied in medical treatment comprises dissolving sodium hydroxide in n-propyl alcohol, isopropyl alcohol or mixtures thereof so as to prepare a solution of the sodium hydroxide, dissolving the pheophorbide a in a solvent miscible with the sodium hydroxide solvent so as to prepare a solution of the pheophorbide a and dissolving the solution of the pheophorbide a in the solution of the sodium hydroxide so as to obtain sodium pheophorbide a. Thus, the water-soluble pheophorbide a can be safely used.

TL;DR: In this paper, the preparation method of isopropanol comprises the following steps: (1) adding conventional strong-acid cation-exchange resin into a low-carbon alcohol solvent, soaking for 8-24 hours at a temperature of 50-150 DEG C, then introducing inert gas in three stages, and obtaining a catalyst applied to hydrolysis reaction of isOPropyl acetate after modification is completed.
Abstract: The invention provides a preparation method of isopropanol. The preparation method of isopropanol comprises the following steps: (1) adding conventional strong-acid cation-exchange resin into a low-carbon alcohol solvent, soaking for 8-24 hours at a temperature of 50-150 DEG C, then introducing inert gas in three stages, and obtaining a catalyst applied to hydrolysis reaction of isopropyl acetate after modification is completed; (2) hydrolyzing isopropyl acetate and water in the presence of a strong-acid cation-exchange resin catalyst modified in the step (1) to generate a mixture with isopropyl alcohol and acetic acid, separating the mixture to obtain isopropyl alcohol, and concentrating the acetic acid and then recycling the acetic acid. The method has the advantages of simple processes, high conversion rate and low energy consumption.

TL;DR: In this article, the authors proposed a method to obtain a polyurethane foam by mixing one or a plurality of organic carboxylic acid salts of tertiary amine compounds with a 1-6C monoalcohol organic solvent in an amount of 10-40wt.
Abstract: PURPOSE: To enable to form a catalyst for polyurethane foam which can stably retain its effective retarding effect by mixing an organic carboxylic acid salt of a tertiary amine compound with a specified amount of a monoalcohol organic solvent. CONSTITUTION: This catalyst for polyurethane foam is formed by mixing one or a plurality of organic carboxylic acid salts of tertiary amine compounds with a 1-6C monoalcohol organic solvent in an amount of 10-40wt.% based on the both. As the organic carboxylic acid salt, one produced by using 0.1-1.0 equivalent, per equivalent of the nitrogen atoms of the tertiary amine compound, of a monobasic organic carboxylic acid is desirable. As the above organic carboxylic acid, formic acid is particularly desirable. As the monoalcohol organic solvents, methyl alcohol, ethyl alcohol, isopropyl alcohol, etc., are desirable.
