PURPOSE: To separate a ketone from an alcohol by allowing a mixture of ketone/alcohol to react with a specified organo-metallic compd. ;CONSTITUTION: The mixture of ketone/alcohol is allowed to react with at least one kind of organo-metallic compd. represented by the formula M(X) n (where...
by calcination in an oxygen or in a stream of ammonia, and in their subsequent steam treatment at various temperatures, as well as beta zeolites exchanged with alkaline metal ions, were investigated in the MPV reduction of 4- tert-butyl cyclohexanone to 4- tert-butyl hexanol using isopropanol....
ketone的中文翻译是酮(kěn)。酮是有机化合物的一类,其分子中含有一个碳氧双键,即一个酮基,通式为R-CO-R'。酮类化合物可通过将卡宾与氧化物进行偶联反应得到。 以下是10个双语例句: 1. Acetone is a common ketone that is used as a solvent.丙酮是一种常用的酮类化合物,用作溶剂。 2. The ketone gr...
Ketone, any of a class of organic compounds characterized by the presence of a carbonyl group in which the carbon atom is covalently bonded to an oxygen atom. The remaining two bonds are to other carbon atoms or hydrocarbon radicals. The most important k
Initial conversion to the N-butenyl derivative (29) allowed reduction of the ester unit to an alcohol and oxidation back to the aldehyde, 43. A Wittig reaction followed by hydrolysis with aqueous acid gave 109.67b Sign in to download full-size image 1.5.2 Synthesis of Alkaloids and Other ...
alcohol. Butylene is produced from oil cuts. However, petroleum is a recognized finite resource and is pointed out as a major cause of environmental issues. An alternative to improve a process is process intensification (PI). In this work, an intensified alternative to produce MEK from 2,3- ...
If your blood sugar spikes or you've had too much alcohol, it can cause your ketone levels to rise to dangerously high levels, a condition calledketoacidosisthat is a medical emergency. Can ketones mean diabetes? People withtype 1 diabetesare at higher risk of developing diabetes-related ketoaci...
Mono-, di- and tri-ketones of polyoxyalkylene compounds prepared by a method whereby the terminal hydroxyl groups of polyoxyalkylene compounds are oxidized to ketone groups with an alkali metal or an alkaline earth metal hypochlorite oxidant in the presence of acetic acid are disclosed. These compoun...
