2-Nitrophenol sodium salt is a polymer film used in wastewater treatments. It effectively prevents bacterial growth through interactions with the active components within the polymer matrix. 2-Nitrophenol Sodium Salt is also used as a beneficial nutrient solution for potatoes. It exhibits an acidic nature, with a pH range between 3 and 4, enhancing its versatility and utility in various contexts.
Sodium o-nitrophenolate is commercially synthesiz=sed by nitrating o-cresol or phenol to form o-nitrophenol, followed by neutralisation with sodium hydroxide. The production process begins with the nitration of phenol, typically using a mixture of nitric and sulphuric acids, to introduce a nitro group at the ortho position, yielding o-nitrophenol. This intermediate is then neutralized with sodium hydroxide to form the sodium salt, which improves solubility and stability for agricultural formulations. The reaction is conducted under controlled temperature and pH conditions to ensure selectivity and minimise byproducts.
