Mankhwala katundu
Zamadzimadzi zowoneka bwino zopanda mtundu zokhala ndi fungo la amine.Zitha kukhala intersoluble ndi madzi, mowa, etha, ester, ketone, halogenated hydrocarbon, onunkhira hydrocarbon.
mwachidule
N-methyl pyrrolidinone mwachidule, chilinganizo cha maselo: C5H9NO, Chingerezi: 1-methyl-2-PyrrolidinOne, mawonekedwe ake ndi opanda utoto mpaka kuwala achikasu owonekera amadzimadzi, ndi fungo la ammonia pang'ono, osokonekera ndi madzi mwanjira iliyonse, amasungunuka mu ether, acetone ndi ester, halogenated hydrocarbon, onunkhira hydrocarbon ndi zina zosungunulira organic, Pafupifupi kusakaniza zonse zosungunulira Chemicalbook, otentha mfundo 204 ℃, kung'anima mfundo 91 ℃, hygroscopic, khola mankhwala katundu, palibe dzimbiri kwa carbon zitsulo, zotayidwa, zowononga pang'ono mkuwa.Zili ndi ubwino wa kukhuthala kochepa, kukhazikika kwa mankhwala ndi kutentha, polarity yapamwamba, kusinthasintha kochepa, kusokonezeka kosatha ndi madzi ndi zosungunulira zambiri za organic, etc. Mankhwalawa ndi mankhwala ang'onoang'ono, malire ovomerezeka a mlengalenga ndi 100PP.
Ntchito zazikulu
(1.) Gulu la mafakitale:
Kupaka mafuta, kudzoza mafuta oletsa kuzizira, syngas desulfurization, zipangizo zamagetsi zamagetsi, mankhwala ophera tizilombo, mankhwala ophera tizilombo, PVC kuchira gasi wa mchira, zokutira zapamwamba, inki, kupanga pigment zowonjezera ndi dispersants.Mwachitsanzo, amagwiritsidwa ntchito potulutsa zonunkhira m'mafuta opaka mafuta kuti akwaniritse cholinga choyenga mafuta opaka;Chifukwa cha kusungunuka kwakukulu kwa utomoni wa NMP, monga chosungunulira cha utomoni wosungunulira ukhoza kugwiritsidwa ntchito makamaka popanga zokutira, utoto wapansi, varnish, filimu yamagulu ❖ ❖ kuyanika, filimu yosakanikirana ya enameled waya, nsalu za fiber ndi zomatira ndi zinthu zina.
(2.) Mulingo Wamba:
M'zigawo ndi kubwezeretsa zinthu zofunika organic, monga acetylene m'zigawo ndi butadiene, isoprene, aromatics ndi m'zigawo zina.Angagwiritsidwe ntchito ngati zosungunulira kuti achire acetylene ku gasi kapena kuwala naphtha pyrolysis mpweya.Monga chotsitsa cholekanitsa ndi kubwezeretsanso chiyero chapamwamba cha butadiene kuchokera ku kuwonongeka kwa C4 hydrocarbon, chiwongoladzanja ndi 97%, ndipo chiyero cha kuchira butadiene ndi 99.7%.Monga chopangira kuti chiwongolero cha isoprene choyera kwambiri kuchokera pakusweka kwa C5 hydrocarbon, kuyeretsa kwa isoprene ndi 99%.Chifukwa cha kusungunuka kwake kwakukulu komanso kutsika kwamphamvu kwa nthunzi kwa aromatics, kutayika kwa wothandizila m'zigawo kumakhala kochepa komanso kuchira kwa aromatics ndikokwera.
(3.) Mulingo wa reagent:
Integrated dera, litayamba zolimba ndi zina zofunika kulamulira okhwima ayoni zitsulo ndi particles makampani deoiling, degreasing, dewaxing, kupukuta, kupewa dzimbiri, utoto, monga photoresist kuchotsa madzi, IC semiconductor makampani mwatsatanetsatane zida, LCD madzi galasi zipangizo, PCB kusindikizidwa dera bolodi, zolimba litayamba kuyeretsa;Komanso yokumba impso zinchito nembanemba madzi, nyanja desalination nembanemba madzi ndi zosungunulira ena opangidwa ndi makampani mankhwala.
