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. 82998-57-0, name is 3-Iodo-4-methylbenzoic acid belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. name: 3-Iodo-4-methylbenzoic acid
To a solution of 3-iodo-4-methylbenzoic acid (15 g, 57.14 mmol) in methanol, concentrated sulfuric acid was slowly added dropwise. The reaction solution was allowed to exotherm. After addition, the solution was heated to 70 C. the reaction monitored by TLC was completed 48 h later. The methanol was evaporated under reduced pressure to give brown oil which was slowly poured into 200 mL of water, and the mixture was milk white with heat emission. The aqueous phase was extracted with DCM twice. The DCM layer combined was washed successively with aqueous sodium bicarbonate solution, saturated aqueous sodium chloride solution, water once. The DCM layer was dried over anhydrous sodium sulfate and evaporated to dryness under reduced pressure to give the title product as a yellowish brown oil.
The synthetic route of 82998-57-0 has been constantly updated, and we look forward to future research findings.
