NMP在锂电池涂布机工艺中监测的重要性：
NMP-甲基吡咯烷酮,是一种以γ-丁内酯为原料,与甲胺缩合而成液体,挥发性、渗透性极强,PH值为7-9碱性,易燃易爆,在锂电池生产中应用广。在锂电池电极制造过程中,涂布机浆料中的溶剂NMP经加热后会形成气态，NMP气体有毒性，对人体有伤害。
另外，NMP与空气混合时有爆炸的可能。因此NMP的监测与回收不仅关系到电池生产企业的节能减排效益，更是攸关人员健康与生命**的头等大事。
NMP特性：
分子式：C5H9NO ，分子量：99.1322，CAS号：872-50-4。无色透明油状液体，微有胺的气味。熔点-24.4℃。沸点203℃；150℃(30.66kPa)；135℃(13.33kPa)；81～82℃(1.33kPa)。闪点95℃。相对密度1.0260(25/25℃)。折射率nD(25℃)1.486。粘度(25℃)1.65mPa·s。能与水、醇、醚、酯、酮、卤代烃、芳烃互溶。挥发度低，热稳定性、化学稳定性均佳。大鼠口服毒性LD50＝3914mg/kg, 兔子经皮毒性LD50=8000mg/kg。
