18480-53-0, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3,4-Dichloroisothiazole-5-carboxylic acid, cas is 18480-53-0,the isothiazole compound, it is a common compound, a new synthetic route is introduced below.
After 10 g of 50 mmol of 3,4-dichloro-isothiazole carboxylic acid II was added to 100 ml flask was added 30 ml of thionylchloride, refluxed for 5 hours, thionyl chloride was distilled off at atmospheric pressure, the residue was water pump vacuumdistillation at 100-110 degrees C compound fraction collected between 10.6 g yellow solid 3,4-dichloro-isothiazole carboxylicacid chloride III, a yield of 96.3percent, 3,4-dichloro-isothiazole carboxylic acid chloride III prepared a pro rata amount of expanded orreduced, the volume of the reaction vessel according to the corresponding scaled up or down, a commercially availablecompound II has the same effect.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 18480-53-0, 3,4-Dichloroisothiazole-5-carboxylic acid
