Chlorine is one of the most widely used chemicals in water purification. It is a powerful disinfectant that kills bacteria, viruses, and other pathogens present in water. Chlorination is often used in municipal water treatment plants and involves adding chlorine gas, sodium hypochlorite, or calcium hypochlorite to water. The process not only eliminates harmful microorganisms but also helps in the removal of unpleasant odors and tastes. However, the use of chlorine must be carefully monitored, as its reacts with organic matter can lead to the formation of byproducts such as trihalomethanes (THMs), which can pose health risks.
Once a candidate API is identified, the synthesis process begins. This process typically involves multiple chemical reactions to transform raw materials into the desired compound. Depending on the complexity of the API, the synthesis may require a series of steps, including reaction conditions like temperature and pressure, the use of catalysts, and solvent selection. The aim is to achieve high yield and purity while minimizing by-products. Advanced technologies such as continuous flow chemistry and green chemistry practices are increasingly being adopted to enhance efficiency and reduce environmental impact.
