Chaw tsim tshuaj paus zoo nqe n-Ethyl pyrrolidone (NEP) CAS: 2687-91-4

Cov lus piav qhia luv luv:

NEP yog cov kua tsis muaj xim thiab pob tshab nrog cov xim zoo nkauj, qib siab tshuaj ruaj khov thiab siab thermal ruaj khov. Nep yog point point yog 82-83 ° C (-101.3kpa), cov khoom siv hluav taws xob tsis zoo yog 1.4665 spechbook, thiab qhov ceev yog 0.994. NEP muaj cov yam ntxwv ntawm kev ua kom siab solubility, qis vapor siab thiab tsis tshua muaj dielectric tas li. Kev lag luam muaj, NEP tuaj yeem siv los ua cov kuab tshuaj uas muaj txiaj ntsig zoo, catalyst thiab cationic surfactant.

N-Ethyl pyrrolidon muaj qaug zog alkali; NEP yog cov kuab tshuaj muaj zog polar uas tuaj yeem ua rau muaj cov roj ntsha uas qhuav huv si Cov.
