Codsiga Vanilyl butyl ether CAS 82654-98-6

N-methylpyrrolidone waxaa loogu yeeraa NMP si gaaban, qaacidadeeda molecular waa c5h9no. Ingiriisi: 1-methyl-2-pyrrolidinone. Waa dareere hufan oo huruud ah oo aan midab lahayn ama iftiin leh oo leh ur yar oo ammonia ah. Waxay ku milmi kartaa biyaha qayb kasta, waxayna ku milmaysaa dareerayaasha kala duwan ee organic sida ether, acetone, esters, hydrocarbons halogenated, aromatics, iwm. waxay ku dhawaad ​​​​dhammaan isku dhafan yihiin dhammaan dareerayaasha ku jira buugga kiimikada. Barkeeda karkaraya waa 204 â, barta iftiimaya waa 91 â, waxayna leedahay hygroscopicity xooggan, sifooyin kiimikaad oo deggan, mana daxaloobayso birta kaarboonka iyo aluminiumka, Wax yar u daxalaysa naxaasta. Waxay leedahay faa'iidooyinka viscosity hoose, kiimiko wanaagsan iyo xasilloonida kulaylka, polarity sare, isbedel hoose, iyo miscibility aan xad lahayn oo biyo ah iyo qaar badan oo dareere organic. Alaabtani waa daroogo yar-yar, iyo xadaynta xaddidan ee hawadu waa 100ppm.
