At room temperature, due to the formation of hydrogen bonds between N-Methyl-2-Pyrrolidone and water, the hydrolysis rate of NMP is about 1%, and at high temperatures due to the destruction of hydrogen bonds, the hydrolysis rate of NMP remains at about 2.5%, so when only water is present in NMP The hydrolysis rate is small at both high temperature and room temperature. After adding NaOH, in the NMP containing NaOH solution at room temperature, water inhibits the hydrolysis of NMP to a certain extent, but after a certain amount, due to dissolution Partially non-ionized NaOH, the alkaline environment reduces the activation energy required for NMP to break the C-N bond, thereby intensifying the hydrolysis of NMP.
