Chaw tsim tshuaj paus Zoo Nqe N-ETHYL PYRROLIDONE (NEP) CAS: 2687-91-4

piav qhia luv luv:

NEP yog cov kua tsis muaj xim thiab pob tshab nrog cov polarity siab, tshuaj lom neeg ruaj khov thiab siab thermal stability.NEP yog boiling point yog 82-83 ° C (-101.3Kpa), lub refractive index yog 1.4665 Chemicalbook, thiab qhov ceev yog 0.994.NEP muaj cov yam ntxwv ntawm siab solubility, tsis tshua muaj vapor siab thiab tsis tshua muaj dielectric tas li.Kev lag luam, NEP tuaj yeem siv los ua cov kuab tshuaj muaj txiaj ntsig zoo, catalyst thiab cationic surfactant.

N-ETHYL PYRROLIDON muaj qaug zog alkali;NEP yog ib tug muaj zog polar organic solvent uas yuav yaj nrog ib tug proportional proportions nrog dej thiab cov organic solvents.NEP yog ib tug divestitist ntawm lithium roj teeb, qhuav kua nplaum txawj, thiab kho qhov muag resistant corrosion agent, txheej unfolding tus neeg saib xyuas, thiab epoxy resin kua nplaum ntug .
