Kufotokozera mwachidule:

p-Toluenesulfonamide, yomwe imadziwikanso kuti 4-toluenesulfonamide, p-sulfonamide, toluene-4-sulfonamide, toluenesulfonamide, p-sulfamoyltoluene, ndi flake yoyera kapena tsamba Chemicalbook crystal, yomwe imagwiritsidwa ntchito popanga chloramine-T ndi Chloramphenicol, utoto wa fluorescent, kupanga utoto wapulasitiki , ma resins opangira, zokutira, mankhwala ophera tizilombo komanso zowunikira matabwa, ndi zina.
p-Toluenesulfonamide ndi plasticizer olimba kwambiri kwa mapulasitiki thermosetting, oyenera phenolic utomoni, melamine utomoni, urea-formaldehyde utomoni, polyamide ndi utomoni zina. Kusakaniza pang'ono kumatha kupititsa patsogolo kusinthika, kuchiritsa bwino, ndikupatsa mankhwalawo gloss yabwino. p-Toluenesulfonamide alibe kufewetsa zotsatira za plasticizers madzi, n'zosagwirizana ndi polyvinyl kolorayidi ndi vinilu kolorayidi copolymers, ndipo pang'ono n'zogwirizana ndi mapadi acetate, mapadi acetate butyrate ndi mapadi nitrate.
Njira yopangira imawonjezera gawo la madzi a HN3 mumphika, amawonjezera p-toluenesulfonyl chloride pamene akuyambitsa, ndipo kutentha kumakwera mwachibadwa kufika pamwamba pa 50 ° C. Kutentha kumatsika, madzi otsala a ammonia amawonjezeredwa. Yankhani pa 85 ~ 9Chemicalbook0 ℃ kwa 0.5h. Zomwe zimatha pamene pH ifika 8 mpaka 9. Kuziziritsa mpaka 20 ° C, fyuluta, ndikutsuka keke ya fyuluta ndi madzi kuti mupeze zinthu zopanda pake. Chogulitsacho chimasinthidwa ndi kaboni wopangidwa ndi activated, kusungunuka mu alkali, olekanitsidwa ndi asidi, amasefedwa ndikuwumitsidwa kuti apeze mankhwalawo.

    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
