Kufotokozera mwachidule:

p-Phenylenediamine (Chingerezi p-Phenylenediamine), yomwe imadziwikanso kuti Ursi D, ndi imodzi mwamadiamine osavuta onunkhira. Chovala choyera ndi choyera mpaka makristalo a lavenda, omwe amasanduka ofiirira kapena oderapo akakhala pamlengalenga.
mtundu. Kusungunuka pang'ono m'madzi ozizira, kusungunuka mu ethanol, ether, chloroform ndi benzene.
Itha kugwiritsidwa ntchito popanga utoto wa azo, ma polima apamwamba kwambiri, ndipo itha kugwiritsidwanso ntchito kupanga utoto waubweya, ma antioxidants amphira ndi opanga zithunzi. Amagwiritsidwa ntchito makamaka pa ma aramid, azo dyes, utoto wa sulfure, utoto wa asidi, komanso angagwiritsidwe ntchito ngati ubweya wakuda D. Kupanga Mao Pi Black DB, Mao Pi Brown N2, ndi Chemicalbook rabara antioxidants DNP, DOP, ndi MB. Amagwiritsidwanso ntchito ngati zopangira zodzikongoletsera tsitsi la Ursi D mndandanda, petulo polymerization inhibitor ndi wopanga. Monga utoto wamankhwala, p-phenylenediamine panopa amaloledwa kugwiritsidwa ntchito popanga utoto wa tsitsi, koma pali zoletsa zomveka pa kuchuluka kwa ntchito.
Imapezedwa pochepetsa p-nitroaniline ndi ufa wachitsulo mu acidic sing'anga. Ikani ufa wachitsulo mu hydrochloric acid, kutentha mpaka 90 ° C, ndi kuwonjezera p-nitroaniline pamene mukuyambitsa. Pambuyo pomaliza, itani pa 95-100 ° C kwa 0.5h, ndiyeno yikani hydrochloric acid dropwise kuti mutsirize kuchepetsa Chemicalbook reaction. Mukaziziritsa, chepetsani ndi sodium carbonate solution yokhala ndi pH 7-8, wiritsani ndi fyuluta mukatentha, ndikutsuka keke ya fyuluta ndi madzi otentha. Phatikizani zosefera ndi madzi ochapira, sungani pansi pa kupanikizika kocheperako, crystallize ndi kuziziritsa kapena distill pansi pa kupanikizika kochepa kuti mupeze p-phenylenediamine ndi zokolola za 95%.

    Zolemba Zamalonda

    Chiyambi cha malonda

    N-methylmorpholine ndi yofunika kwambiri pamankhwala apakati. Ndi zosungunulira zabwino kwambiri, emulsifier, corrosion inhibitor, polyurethane foam catalyst, ndipo itha kugwiritsidwanso ntchito ngati mankhwala apakati. The kaphatikizidwe njira Chemicalbook makamaka monga N-methylation njira ntchito morpholine monga zopangira, njira cyclization ntchito diethanolamine monga zopangira, njira cyclization ntchito diethanolamine monga zopangira, ndi kaphatikizidwe njira ntchito dichloroethane monga zopangira, etc.

    Munda wofunsira

    N-Methylmorpholine ndi zosungunulira zabwino kwambiri za utoto, tyrosol, sera ndi shellac, etc.; extractant, stabilizer kwa chlorinated hydrocarbons, analytical reagents, catalysts, corrosion inhibitors; amagwiritsidwanso ntchito ngati accelerator labala ndi mankhwala ena abwino kaphatikizidwe; amagwiritsidwanso ntchito ngati chothandizira polyurethane, chothandizira kaphatikizidwe ka ampicillin ndi hydroxybenzyl penicillin, etc.

    Ndiwogwiritsidwa ntchito kwambiri wapakatikati ndipo chitha kugwiritsidwa ntchito popanga utoto wa azo ndi ma polima apamwamba kwambiri. Itha kugwiritsidwanso ntchito kupanga utoto waubweya, ma antioxidants amphira ndi opanga zithunzi. Kuphatikiza apo, p-phenylenediamine imagwiritsidwanso ntchito poyesa chitsulo ndi Copper sensitive reagent.

    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
