N-Methyl-2-Pyrrolidone (NMP) is an important organic solvent widely used in various fields, including chemicals, pharmaceuticals, electronics, and energy. Due to its excellent solubility, NMP plays a significant role in batteries, electrolytes, coatings, and oilfield chemicals. To meet industrial production demands, the process of NMP production is crucial. Overview of NMP Preparation Methods The main industrial synthesis methods for NMP are: · γ-butyrolactone (GBL) and methylamine reaction method · 2-pyrrolidone methylation method · Carbamate reduction method Among these, the γ-butyrolactone and methylamine reaction method is considered the most common and efficient method for industrial production. Let’s take a closer look at the specific steps and principles of this method. I. Synthesis of NMP by γ-Butyrolactone and Methylamine Reaction Reaction Principle: This method involves reacting γ-butyrolactone (GBL) with methylamine (CH₃NH₂) to produce NMP and ...
