| Use | Introduction Jones reagent, also known as Jones reagent, is a reagent for selective oxidation of organic compounds. It can oxidize secondary alcohols into corresponding ketones without affecting the double or triple bonds in the molecule; it can also oxidize allyl alcohol (primary alcohol) into aldehydes. Generally, secondary alcohol or allyl alcohol is dissolved in acetone or dioxymethane, and then the reagent is dropped for oxidation reaction. The reaction is generally carried out below room temperature. |

Sulfuric acid-chromium trioxide mixture - Introduction
EDTA methidium propylamide(EDTA methidium propylamide), also known as methyl bromide EDTA methidium propylamide, is an organic compound. The following is a description of the nature, use, formulation and safety information of EDTA methidiumpropylamide:
Nature:
EDTA methidiumpropylamide is a colorless or pale yellow crystal, soluble in water and organic solvents. Its chemical structure contains EDTA (ethylenediaminetetraacetic acid) and methyl groups.
Use:
EDTA methidiumpropylamide is mainly used for oxidation reactions in organic synthesis. It can oxidize an alcohol, aldehyde or ketone to the corresponding carboxylic acid. In addition, EDTA methidiumpropylamide can also be used to identify whether chemical substances contain double bonds or oxygen-containing functional groups.
Method:
The method for preparing EDTA methidiumpropylamide is to react EDTA with trimethylamine bromide under alkaline conditions, and obtain the final product through extraction and crystallization.
Safety Information:
EDTA methidiumpropylamide needs to be handled carefully because it is an oxidant and has certain toxicity. Avoid contact with combustibles, reducing agents or inflammables during use, and avoid inhalation or skin contact. Wear appropriate protective equipment, such as chemical protective gloves and goggles. At the same time, EDTA methidium propylamide should be stored in sealed containers, away from ignition and heat sources. When disposing of waste, it is necessary to dispose of it in accordance with local regulations. Before using EDTA methidium propylamide, it is recommended to consult the relevant safety data sheets and operating manuals and to comply with the relevant laboratory safety regulations.
