N-Methyl-2-pyrrolidone (NMP) ke tharollo ea polar aprotic e nang le melemo ea chefo e tlase, ntlha e phahameng ea ho belisa, solvency e ikhethang, khetho e matla le botsitso bo botle.
E sebelisoa haholo ho hlwekiseng ho ntšoa ha hydrocarbon e nkhang hamonate, acetylene, olefin le diolefin.
E sebelisoa ho hlwekiseng indastering, 'me e sebetsa e le tharollo bakeng sa tlhahiso ea chefo e bolaeang likokoanyana, polasetiki ea boenjiniere, liphahlo, likhoele tsa maiketsetso le lipotoloho tse kopaneng.
E ka boela ea sebelisoa e le sesebelisoa sa ho hloekisa indasteri, sesebelisoa sa ho qhalakanya, dae, setlolo le se thibelang ho hatsela.
N-Methyl-2-pyrrolidone ke solvent e ntle haholo, e sebelisoang haholo ho ntšeng aromatics, ho hloekisa oli ka ho tlotsa, ho ntlafatsa acetylene, karohano ea butadiene le ho tlosa sulfurization ea khase ea synthesis.
E sebelisoa ho qhibilihisa khase, ho tlotsa oli, ho tlotsa oli e thibelang ho hoama, ho ntša olefin, le ho etsa polymerization ea polasetiki ea boenjiniere e sa qhibiliheng.
E ka sebelisoa ho dibolaya-dimela, ho hlwekisa thepa ya ho kwahela, disebediswa tse nepahetseng tsa indasteri ya semiconductor le diboto tsa potoloho, ho kgutlisa mosi wa PVC hape, e le sesepa, tlatsetso ya dae le moemedi wa ho qhalanya.
E sebelisoa mediums bakeng sa dikarabelo tsa polymerization tse kang polasetiki ya boenjiniere le faeba ya aramid.
N-Methyl-2-pyrrolidone e sebediswa e le solvent ya polyvinylidene fluoride le thepa e thusang ya electrode bakeng sa dibetri tsa lithium ion.
tekanyo e phahameng ea bohloeki bakeng sa ho lemoha ICP-MS.
Bakeng sa tlhahiso ea peptide.
Ho paka le ho Romela
25KG/Moropa kapa ho ya ka ditlhoko tsa bareki.
Ke ea thepa e tloaelehileng 'me e ka tlisoa ka leoatle le moea
Boloka le ho boloka
Nako ea ho boloka: Likhoeli tse 24 ho tloha letsatsing la tlhahiso ka har'a sephutheloana sa pele se sa buloang se bolokiloe sebakeng se pholileng se omileng se se nang khanya ea letsatsi, metsi.
Ntlo ea polokelo e nang le moea o kenang, Ho omisa mocheso o tlase, E arotsoe ho li-oxidant, li-acid.
