Methods In this procedure, a carboxylic acid was converted to a mixed anhydride using mesyl chloride in the presence of a base. This mixed anhydride was then reacted with a suitable organometallic reagent at 20 掳C to obtain the desired ketone. The reaction was performed in a one pot ...
reported that ketonization of carboxylic acid into ketone over a mixed oxide of Fe, Ce, and Al is another approach to stabilize and upgrade pyrolysis oil [16], [17]. In catalytic upgrading of pyrolysis oil, the high water content should be considered because water will deactivate the ...
Understanding the reaction mechanism of methanol conversion is essential for the development of high-performance catalysts and optimization of chemical process, but is rather challenging due to the complex reaction network involved in such reaction3,8,9,10. Fig. 1: Roles of aldehyde/ketone in ...
To convert acetaldehyde (CH₃CHO) to 2-phenyl-2-propanol ((CH₃)₂C(OH)Ph), we will follow a multi-step synthesis involving Grignard reagents and oxidation. Here’s a step-by-step breakdown of the process:Step 1: Formation of Grig
Oxidizing cycloalkane (5-12 carbons)to form a mixture of ketone, alcohol and unreacted cycloalkane; adding alkali metal hydroxide or carbonate; to form a f... A system and a method for preparing cycloalkanone are provided. The method includes the steps of: (a) oxidizing cycloalkane to for...
10, namely a ketoacid, a ketone and an aromatic, respectively. In general, it is observed that the performance of these compounds were the worst among all the tested classes. The reason could be ascribed to the presence of recalcitrant groups (ketonic, carboxylic, aromaticity) that do not ...
A new peak at 1600 cm−1 emerged after delignification, indicating the presence of functional groups such as aldehyde, ketone, ester, and carboxylic acid, likely resulting from the enzymatic activity on the aromatic structure of lignin. Spectral analysis revealed potential glycosidic linkages in ...
To convert propionic acid (CH3CH2COOH) to acetic acid (CH3COOH), we can follow these steps:Step 1: Convert Propionic Acid to Amide - Reaction: Propionic acid (CH3CH2COOH) is reacted with ammonia (NH3) and heate
