4-Pyridinecarboxylic acid, also known as isonicotinic acid, is synthesized by many methods. The ancient synthesis method often relies on the technique of chemical transformation.
First, pyridine is used as the starting material and can be prepared by oxidation. In the past, strong oxidants, such as potassium permanganate, acted on pyridine. Under appropriate reaction conditions, the methyl groups on the pyridine ring can be oxidized to carboxyl groups to obtain 4-pyridinecarboxylic acid. This reaction requires careful temperature control, because the severity of the reaction conditions depends on the purity and yield of the product. If the temperature is too high, it is easy to cause the pyridine ring to break and damage the product; if the temperature is too low, the reaction will be slow and take a long time. < Br >
Second, 4-methylpyridine is used as raw material and obtained by catalytic oxidation. In the past, specific catalysts, such as metal oxide catalysts, were selected. Under suitable temperature, pressure and aerobic environment, the methyl group of 4-methylpyridine can be gradually oxidized to carboxyl groups. In this process, the activity and selectivity of the catalyst are the key. High activity results in a fast reaction rate, but poor selectivity, prone to side reactions and mixed products. Therefore, fine screening and regulation of catalysts are required to achieve the desired synthesis effect.
Third, there are also those who use nitrogen-containing heterocyclic compounds as starting materials to construct pyridine rings through multi-step reactions, and then introduce carboxyl groups to form 4-pyridine carboxylic acid. Although this approach is complicated, it can be flexibly adjusted according to the characteristics of different starting materials, and it is also feasible in some specific situations. Each step of the reaction requires strict control of conditions, such as the ratio of reactants, the solvent of the reaction, and the reaction time, which all have a profound impact on the formation of the final product.
