Ethylenediaminetetraacetic asidi CAS: 60-00-4
mankhwala katundu
Izi zimatuluka m'madzi ngati ufa woyera. Kusungunuka m'madzi pa 25 ℃ ndi 0.5g/L. Insoluble m'madzi ozizira, mowa ndi zonse organic solvents. Kusungunuka mu sodium hydroxide, sodium carbonate ndi ammonia solutions.
Njira yopangira:
Kuchita kwa ethylenediamine ndi chloroacetic acid. Onjezani 100kg ya chloroacetic acid, 100kg ya ayezi ndi 135kg ya sodium hydroxide solution (30%) mu ketulo yomwe mumachitira, ndiyeno onjezerani 18kg ya 83% mpaka 84% ethylenediamine pogwedeza. Yalirani pa 15 ° C kwa ola limodzi. Onjezani 30Chemicalbook% sodium hydroxide solution mumagulu a 10L nthawi iliyonse. Pambuyo powonjezerapo, onjezerani gulu lina pambuyo poti yankho la phenolphthalein silikuwonetsa zofiira. Sungani kutentha kwa 12h. Kutenthetsa mpaka 90 ° C ndikusintha mtundu ndi activated carbon. Sefa, sambani zotsalira za fyuluta ndi madzi, ndipo pamapeto pake sinthani pH kukhala 3 ndi hydrochloric acid. Kuziziritsa ndi crystallize, fyuluta ndi kusamba ndi madzi mpaka palibe chloride ion reaction. Zouma zouma.
Kuchita kwa ethylenediamine ndi formaldehyde ndi sodium cyanide. Sakanizani 60% ethylenediamine aqueous solution, 30% sodium cyanide aqueous solution ndi sodium hydroxide, ndi kusunga osakaniza pa 20 ° C kwa 0.5h. Kenako onjezerani formaldehyde amadzimadzi yankho dropwise. Zitachitika izi, buku la Chemical lidachepetsedwa ndipo madziwo adasanduka nthunzi. Kenako bwerezani opareshoni pamwambapa, ndikuwonjezera formaldehyde komaliza kuti sodium cyanide ichitepo kanthu. Sinthani pH kukhala 1.2 ndi dilute acid. Mvula yoyera imagwa, kusefa, kutsukidwa ndi madzi, ndikuwumitsa pa 110 ° C. Pezani mankhwala.
Munda wofunsira
Ethylenediaminetetraacetic acid (EDTA) ndi chinthu chofunikira kwambiri chophatikiza. EDTA chimagwiritsidwa ntchito ndipo angagwiritsidwe ntchito ngati bleaching fixative mu processing wa zipangizo mtundu photosensitive, utoto wothandiza, CHIKWANGWANI processing wothandiza, zodzikongoletsera zina, magazi anticoagulants, detergents, stabilizers, kupanga mphira polymerization initiators, EDTA ndi chelate Woimira zinthu zosakaniza. Itha kupanga mamolekyu okhazikika osungunuka m'madzi okhala ndi zitsulo zamchere, zinthu zosowa zapadziko lapansi ndi zitsulo zosinthika. Kuphatikiza pa mchere wa sodium, palinso ammonium salt ndi mchere wosiyanasiyana monga chitsulo, magnesium, calcium, mkuwa, manganese, zinki, cobalt, ndi aluminium. Mchere uliwonse uli ndi ntchito zosiyanasiyana. Kuphatikiza apo, EDTA itha kugwiritsidwanso ntchito kutulutsa mwachangu zitsulo zowopsa za radioactive m'thupi la munthu ndikuchita gawo lochotsa poizoni. Ndiwothandiziranso madzi. EDTA imakhalanso chizindikiro chofunikira, koma imagwiritsidwa ntchito kutsitsa nickel yachitsulo, mkuwa, ndi zina. Mukagwiritsidwa ntchito, iyenera kugwiritsidwa ntchito pamodzi ndi ammonia kuti igwire ntchito ngati chizindikiro.

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
