What are the synthetic methods of 5-iodo-2-nitrobenzoic Acid?
The synthesis method of 5-iodine-2-nitrobenzoic acid has various paths. First, it can be started from benzoic acid. First, the mixed acid of concentrated nitric acid and concentrated sulfuric acid is used to nitrate benzoic acid at a suitable temperature to obtain 2-nitrobenzoic acid. This step requires temperature control to prevent side reactions from occurring. Due to the strong oxidation of nitric acid, the temperature is too high or excessive nitrification is caused. Then, iodine and an appropriate oxidant, such as hydrogen peroxide or periodate acid, are used in a suitable solvent, such as glacial acetic acid, to iodize 2-nitrobenzoic acid, and finally 5-iodine-2-nitrobenzoic acid.
Second, start from o-nitrotoluene. First, halogen (such as bromine), under the action of light or initiator, is halogenated at methyl to obtain o-nitrobenzyl halides. Then oxidized, such as potassium permanganate or potassium dichromate strong oxidant, under alkaline conditions, halobenzyl is oxidized to carboxyl groups to obtain 2-nitrobenzoic acid derivatives. Finally, iodized as before to obtain the target product.
Or, with 2-nitro-5-aminobenzoic acid as a raw material. After diazotization, sodium nitrite and hydrochloric acid are used to convert the amino group into a diazo salt at low temperature. Then reacted with potassium iodide, the diazo group is replaced by iodine, and then 5-iodine-2-nitrobenzoic acid is obtained. This method of synthesis has its own advantages and disadvantages, and it is necessary to choose the best one according to the actual situation, such as the availability of raw materials, cost, and difficulty of reaction conditions.
5-iodo-2-nitrobenzoic Acid in storage and transportation
5-Iodine-2-nitrobenzoic acid is an organic compound. When storing and transporting, many matters need careful attention.
In terms of storage, the first choice of environment. When placed in a cool and well-ventilated place, the compound is prone to reaction or decomposition due to heat. If the temperature is too high, or its chemical properties change, it will damage the quality. The warehouse must be kept away from fire and heat sources to prevent the threat of open flames, because open flames can easily cause combustion or even explosion. And should be stored separately from oxidants, reducing agents, alkalis, etc., and should not be mixed. This is because 5-iodine-2-nitrobenzoic acid is prone to chemical reaction with the above substances. If it comes into contact with oxidants or reacts violently, it may cause fire or explosion. Suitable materials are required to contain the leakage, in case of leakage, it can be properly handled in time to avoid the spread of pollution.
When transporting, the packaging must ensure that it is tight. Select suitable packaging materials to prevent the compound from being affected by vibration, collision and friction during transportation. Transportation vehicles should be equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. During driving, drivers must drive carefully to avoid violent operations such as sudden braking and sharp turns to prevent package damage. During transportation, it is also necessary to prevent exposure to the sun and rain. If exposed to the sun, the temperature will rise, and the compound will easily decompose; in case of rain, water may react with the compound to change its properties. And it must not be transported by car with oxidants, reducing agents, and alkalis to prevent mutual reaction and endanger transportation safety.
