What is the synthesis method of 3,4-difluorobenzenesulfonamide?

To prepare 3,4-diethoxybenzaldehyde, you can follow the following ancient method.

First take resorcinol, use dimethyl sulfate or dimethyl carbonate as methylation reagent, and methylate phenolic hydroxyl in an alkaline environment to obtain m-methoxyphenol. This step requires moderate temperature control and precise control of alkalinity, otherwise it will affect the yield and purity.

Then, m-methoxyphenol and bromoethane are used as raw materials, and under the action of alkaline catalysts such as sodium alcohol, nucleophilic substitution is performed to generate 3,4-dimethoxyphenethyl ether. The choice of solvent, the proportion of reactants and the duration of the reaction are all related to the effectiveness of the product.

Then 3,4-dimethoxy phenethyl ether is added to a suitable organic solvent, and a highly active catalyst, such as a supported metal catalyst, is demethylated in a hydrogen atmosphere to obtain 3,4-diethoxy phenol. This step requires strict catalyst activity and stability, and the reaction conditions need to be finely regulated.

Finally, 3,4-diethoxy phenol is used as the substrate, and a mild oxidant is selected, such as manganese dioxide-sulfuric acid system. At a specific temperature and reaction time, the phenolic hydroxyl group is oxidized to an aldehyde group, and then 3,4-diethoxy benzaldehyde is obtained. During the entire process, the product needs to be properly separated and purified after each step of the reaction to ensure the smooth reaction and the quality of the final product.

What are the precautions for the storage and transportation of 3,4-difluorobenzenesulfonamide?

Lithium 3% 2C4-divinylbenzene sulfonate is an important chemical raw material. When storing and transporting, the following things should be paid attention to:
First, the storage environment is the key. This substance should be placed in a cool, dry and well-ventilated place, and must not be near fire and heat sources. Because of its flammability, it is easy to cause combustion in case of open flames and hot topics. The warehouse temperature should be controlled below 30 ° C, and the relative humidity should not exceed 80%. If the environment is humid, it is easy to cause deliquescence and deterioration, affecting quality and performance. And it should be stored separately from oxidants, acids, alkalis, etc., and must not be mixed to prevent violent chemical reactions.
Second, the packaging must be tight. Packaging materials should have good sealing and corrosion resistance to prevent leakage. Commonly used packaging includes plastic drums, iron drums lined with plastic film, etc. Warning labels should be clearly marked on the outside of the package, such as "flammable" and "corrosive", so that the contact can be clear at a glance and be vigilant.
Third, the transportation process should not be ignored. Transportation vehicles should have corresponding qualifications and be equipped with necessary fire equipment and leakage emergency treatment equipment. During transportation, ensure that the container does not leak, collapse, fall or damage. During driving, bumps and vibrations should be avoided to prevent packaging damage. And the transportation route should try to avoid densely populated areas and water source protection areas. If leakage occurs, it can reduce the harm to the environment and people. When loading and unloading, the operator should wear appropriate protective equipment, such as gas masks, rubber gloves, etc., and handle it lightly. It is strictly forbidden to drop, press, and rub.
