TL;DR: In this article, an immobilized lipase-catalyzed production of isopropyl myristate by esterification of myristic acid with isopsropyl alcohol (molar ratio of 1:15) in the homogenous reaction medium was performed on a bench-scale packed bed reactors, in order to obtain suitable reaction performance data for upscaling.

TL;DR: In this paper, an integrated process for the generation of a mixture of ethers from a crude byproduct acetone stream composed of acetone, tertiary butyl alcohol and methanol by passing such a stream, in the presence of hydrogen, over a catalyst system characterized by having both a hydrogenation activity gradient along the reactor in one direction and an etherification activity gradient in the opposite direction.
Abstract: Disclosed is an integrated process for the generation of a mixture of ethers, such as diisopropyl ether, methyl tertiary butyl ether, and/or isopropyl tertiary butyl ether, from a crude by-product acetone stream composed of acetone, tertiary butyl alcohol and methanol by passing such a stream, in the presence of hydrogen, over a catalyst system characterized by having both a hydrogenation activity gradient along the reactor in one direction and an etherification activity gradient in the opposite direction.

TL;DR: In this article, a reducing agent introduced in exhaust gas before a treatment when NOx in the exhaust emission of internal combustion engine is selectively reduced by a catalyst is prepared from an alcohol solution of urea.
Abstract: PROBLEM TO BE SOLVED: To efficiently carry out exhaust emission controlling over a wide temperature range from low temperature to high temperature by preparing a reducing agent introduced in exhaust gas before treatment from an alcohol solution of urea when NOx in the exhaust gas is subjected to the selection reducing treatment by a catalyst. SOLUTION: A reducing agent introduced in exhaust gas before a treatment when NOx in the exhaust emission of internal combustion engine is selectively reduced by a catalyst is prepared from an alcohol solution of urea. The exhaust gas to which the reducing agent from an injection nozzle 5 is introduced is successively brought into contact with a NOx reducing catalyst of urea, NOx reducing catalyst 7 of alcohol, and an oxidation catalyst 8 of ammonia and alcohol, thereby reducing NOx in the exhaust gas. Alcohol (1-7C alcohol, for example) used for preparing the reducing agent having low specific gravity and low freezing point (fusing point), such as methyl alcohol, ethyl alcohol, and isopropyl alcohol, for example, is used.

20 Apr 1979TL;DR: In this paper, a deodorizing method for lower alcohols such as ethanol and isopropyl alcohol and their derivatives such as ethers and esters is described. But the deodorization process is not described.
Abstract: Methods for deodorizing lower alcohols such as ethanol and isopropyl alcohol and their oxy derivatives such as ethers and esters are disclosed, including contacting these compounds with a deodorizing contact mass comprising, on a support, metals and/or metal oxides, preferably of the metals of Group IB, VIB and VIII of the Periodic Table, where the metal oxides are at least partially reduced to metal and the deodorizing contact mass has a minimum particle dimension of greater than about 0.254 mm so as to be in a form suitable for use in a fixed bed contacting process. In a preferred embodiment, isopropyl alcohol is deodorized employing such deodorizing contact masses, preferably comprising Group VIII metals such as nickel, iron, cobalt and the like, on a support, so that the contact mass has a surface area less than about 1,500 m 2 per gram. Overall isopropyl alcohol finishing procedures are also disclosed employing such deodorizing methods in combination with extractive distillation procedures to produce a high grade, e.g., 91%, and/or anhydrous grade isopropyl alcohol from a crude isopropyl alcohol stream containing more than about 0.0005 percent water.
