methyl-2-pyrrolidone CAS: 872-50-4
Chiyambi cha malonda
N-Methylpyrrolidone imatchedwa NMP, molecular formula: C5H9NO, English: 1-Methyl-2-pyrrolidinone, maonekedwe alibe mtundu mpaka kuwala chikasu mandala madzi, fungo pang'ono ammonia, miscible ndi madzi mu gawo lililonse, sungunuka etha, acetone. Ndipo zosungunulira zosiyanasiyana organic monga esters, halogenated hydrocarbons, onunkhira hydrocarbons, ndi zina zotero, ndi kwathunthu kusakaniza mankhwala pafupifupi zosungunulira zonse, ndi kuwira mfundo 204 ° C ndi kung'anima mfundo 91 ° C. Ili ndi hygroscopicity yamphamvu komanso yokhazikika yamankhwala. Siziwononga zitsulo za carbon ndi aluminiyamu, ndipo siziwononga mkuwa. Zowononga pang'ono. Zili ndi ubwino wa kukhuthala kochepa, kukhazikika kwa mankhwala ndi kutentha kwabwino, polarity yapamwamba, kusasunthika kochepa, komanso kusamvana kopanda malire ndi madzi ndi zosungunulira zambiri za organic. Izi ndi mankhwala ang'onoang'ono, ndipo malire ovomerezeka mumlengalenga ndi 100PPM
Munda wofunsira
N-methylpyrrolidone (NMP) ndi polar aprotic zosungunulira. Ili ndi kawopsedwe wochepa, malo otentha kwambiri komanso kusungunuka kwabwino kwambiri. Ubwino wa selectivity amphamvu ndi kukhazikika kwabwino. Amagwiritsidwa ntchito kwambiri pochotsa aromatics, kuyeretsedwa kwa acetylene, olefins, ndi dienes, zosungunulira za polyvinylidene fluoride, ma elekitirodi othandizira mabatire a lithiamu-ion, syngas desulfurization, kuyenga mafuta, antifreeze yamafuta, ndi olefin m'zigawo. , zosungunulira mu polymerization wa insoluble engineering mapulasitiki, ulimi herbicides, kutchinjiriza zipangizo, Integrated dera kupanga, kuyeretsa zida mwatsatanetsatane ndi matabwa dera mu makampani semiconductor, PVC utsi mpweya kuchira, kuyeretsa wothandizila, utoto zina, dispersants, etc. amagwiritsidwa ntchito ngati chosungunulira cha ma polima ndi sing'anga yopangira ma polymerization, monga mapulasitiki aumisiri ndi ulusi wa aramid. Kuphatikiza apo, itha kugwiritsidwanso ntchito mu mankhwala ophera tizilombo, mankhwala ndi zotsukira, etc.

Zambiri Zamakampani
MIT-IVY INDUSTRY CO., LTD ndi opanga ndi kutumiza kunja kwa utoto wabwino wamankhwala & intermediates mankhwala ku China.
Makamaka kupanga mankhwala aniline mndandanda ndi mankhwala chlorine mndandanda.
Malingaliro a kampani MIT-IVY Chemicals Industry Co.,Ltd. ndi wopanga mankhwala otsogola kwa zaka 21 okhala ndi zida zonse zopangira ndikuwongolera mosamala ndikukonza makina.
Timagwiritsa ntchito ukadaulo wapamwamba wopanga ndi njira zoyesera kuti tikwaniritse kupanga, kuwongolera bwino kuti tikwaniritse zomwe zili. Tavomerezedwa ndi SGS, ISO9001, ISO140 01, GB/HS16949 ndi T28001.
Zogulitsa zazikulu za Mit-Ivy zikuphatikiza izi:
API, intermediates pharmaceutical, Dye intermediates, zabwino, mankhwala apadera, Waterborne mafakitale utoto ndi zipangizo mphamvu zatsopano.
Misika yathu yayikulu ikuphatikizapo America, India, Africa, Indonesia, Turkey, South-East Asia, West Asia ndi zina zotero. MIT-IVY Viwanda Main Zogulitsa zimagawana 97% ya msika wapakhomo wokhazikika pakupanga ndi kasamalidwe, Titha kupereka zinthuzo ndi mtengo wampikisano. ndi mtundu wamtengo wapatali komanso mtengo ndipo mwalandilidwa kuti mukambirane. Kampani yathu ili ndi akatswiri omwe ali ndi luso la R&D ndi kasamalidwe ka sicentific, amapereka mankhwala abwino kwambiri okhala ndi mawonekedwe apamwamba komanso ntchito yapafupi, komanso amapereka zinthu zosinthidwa malinga ndi zomwe makasitomala amafuna. Tili ndi gulu labwino komanso lodzilimbikitsa logwira ntchito loyang'anira lomwe lili ndi nzeru zofananira, chisamaliro ndi kudzipereka kudzera muntchito yamagulu, gulu lathu limayesetsa kuchita bwino pakusangalatsa makasitomala athu komanso ife eni. timapanga zinthu zatsopano mosalekeza ndikupititsa patsogolo ntchito yathu, maukonde ogulitsa. Chifukwa chake, timayambitsa njira yoyamba yogulitsira pa net ku China, yomwe ndi malonda ang'onoang'ono ang'onoang'ono amabweretsa mitundu yosiyanasiyana ya kasamalidwe. Zogulitsa zathu zimatumizidwa ku South Korea, Vietnam, Australia, Europe ndi South America, zomwe zimalimbikitsidwa kwambiri ndi makasitomala athu. Timaumirira pa chikhulupiriro cha kasamalidwe "Msika ndi kampasi yathu, Ubwino ndi moyo wathu, Ngongole ndi moyo wathu". Chikhulupiliro chamakasitomala ndi ufa wathu wakutsogolo, kukhutitsidwa kwawo ndi cholinga chathu chovutikira.
Makasitomala Amtundu Wanu:
Gulu lathu laakaunti lamakasitomala la JIT ku China limapanga ndikugwiritsa ntchito malingaliro opangidwa mwaluso kuti makasitomala athu azipezeka ndi mankhwala azigawo ndi apadera.
Ubwino wanu:
● Utumiki wamakasitomala wapakati umathandizira kuphweka kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake kuti athe kuchepetsa nthawi ndi ndalama.
● Netiweki yathu yaku China komanso njira zotsogola zotsogola zimatsimikizira kuti mankhwala amtundu wofanana amaperekedwa kwa makasitomala okhala ndi malo angapo opangira ndikuthandizira chitetezo pakukonza ndi kudalirika kwa njira.
● Njira zathu zimakongoletsedwa mosalekeza ndikusinthidwa kuti zigwirizane ndi kusintha kwamakasitomala ndi zofunikira.
Ubwino wa ntchito ya Chemistry Logistics:
Utumiki wa Chemical Logistic ndi waukatswiri kwambiri ndipo uyenera kukhala wapamwamba pansi pa nthawi zonse za UN, makamaka pa mndandanda wa DGR Class. Timapereka yankho lachifuno chapadera kuti tikwaniritse gulu lonyamula katundu ndi loyenera komanso ntchito yolembera kwa akuluakulu athu. Madoko athu akuluakulu aku China okhala ndi malo osungiramo mankhwala a DGR ndikugwiritsa ntchito mankhwala apadera ndikugwiritsa ntchito zolemba zonse zomwe zikukhudzidwa.
Kukhoza kwathu kugawa kumaphatikizapo:
● Kutumiza kosinthika, njira zanzeru
● Chilichonse kuyambira katundu wochuluka wa matani masauzande ambiri mpaka katundu wochepa kwambiri ngakhalenso zitsanzo.
● Kuchuluka - kusunga ndi kunyamula ufa ndi zakumwa - kayendedwe ka katundu m'sitima - ufa ndi zakumwa zambiri.
● Pharma, chakudya ndi kusungirako chakudya ku miyezo yovomerezeka
● Zida zosiyanitsidwa ndi magawo abizinesi ndi magulu angozi
● Kusungirako ndi zoyendera zoyendetsedwa ndi kutentha
● Kuwongolera bwino ndalama
● Kulongedzanso, kudzaza ng'oma, kuika matumba, kung'amba ndi kumangirira
● Makasitomala a KPI's pakukwaniritsa kukwaniritsidwa
