Whakaahuatanga
He whakarewa aprotic te N-Methyl-2-pyrrolidone, he whānuitia ana ngā whakamahinga: te tukatuka matū hinu, te paninga mata, ngā tae me ngā wāhanga, ngā matū horoi ahumahi me te whare, me ngā whakatakotoranga ahuwhenua me te rongoā. He mea whakapataritari te nuinga, engari kua puta hoki he maha ngā take o te mate kiri pā ki tētahi kamupene hiko iti.

Whakamahinga
Ngā Whakamahinga
Ko te N-Methyl-2-pyrrolidone (NMP) he whakarewa aprotic porotiki, he iti te paitini, he teitei te ira koropupū, he tino pai te kaha ki te utu, he kaha te whiriwhiri me te pumau.
He whānuitia te whakamahinga mō te purenga o te tangohanga hauwai kakara, te acetylene, ngā olefin, me ngā diolefin.
E whakamahia ana i roto i te horoi ahumahi, ā, he whakarewa hoki mō te hanga patu pepeke, kirihou hangarau, paninga, muka hangai, me ngā ara iahiko whakauru.
Ka taea hoki te whakamahi hei horoi ahumahi, hei whakamarara, hei tae, hei hinu whakahinuhinu me te ārai huka.
He whakarewa pai rawa atu te N-Methyl-2-pyrrolidone, e whakamahia whānuitia ana i roto i te tango kakara, te whakamahine hinu whakahinuhinu, te whakarei ake i te acetylene, te wehenga butadiene me te tango whanariki hau hanga.
E whakamahia ana i roto i te tango whanariki hau, te whakamahine hinu whakahinuhinu, te ārai huka hinu whakahinuhinu, te tango olefin, me te whakarewa mō te whakapūhui kirihou hangarau kore-rewa.
Ka taea te whakamahi i roto i ngā patu taru, hei horoi i ngā rauemi whakamahana, i ngā taputapu tika o te umanga haurua-waenga me ngā papa ara iahiko, hei hangarua i ngā hau putanga PVC, hei hopi horoi, hei tāpiri tae me te kaihoko whakamarara.
E whakamahia ana i roto i ngā reo mō ngā tauhohenga polymerization pērā i te hangarau kirihou me te muka aramid.
E whakamahia ana te N-Methyl-2-pyrrolidone hei whakarewa pūhaumāota polyvinylidene me te rauemi āwhina hiko mō ngā pākahiko lithium ion.
he taumata parakore teitei mō te kimi ICP-MS.
Mō te hanganga peptide.
