Shanghai Huayingtong E-commerce Co., Ltd. is one of the leading Acetonitrile suppliers in China and a professional Acetonitrile manufacturer. Welcome to purchaseAcetonitrile from our factory.pls contact tom :service@skychemwin.com
Igama Lomkhiqizo:I-acetonitrile
Ifomethi ye-Molecular:I-C2H3N
Inombolo ye-CAS:75-05-8
Isakhiwo samangqamuzana omkhiqizo:
Uketshezi olukhanyayo olungenambala. Ixubene namanzi, i-ether, i-methanol, i-acetone, i-chloroform, i-carbon tetrachloride, i-ethylene chloride, i-methyl acetate, i-ethyl acetate, isixazululo se-acetamide nama-hydrocarbon amaningi angagcwele, kodwa hhayi ngama-hydrocarbon agcwele. Ingancibilikisa usawoti wezinto ezingaphili, njengesiliva nitrate, i-lithium nitrate ne-magnesium bromide. Ingenza ingxube ye-azeotropic ngamanzi (aqukethe amanzi angu-16%), enephuzu le-azeotropic elingu-76 ℃. Ukuvutha, umhwamuko nomoya kungakha ingxube eqhumayo, engabangela ukuvutha nokuqhuma uma kuba nomlilo ovulekile, ukushisa okuphezulu noma ukuthintana ne-oxidant. Ingasabela ngokuqinile nge-oxidant. Isabela ngobudlova nge-sulfuric acid, i-oleum, i-chlorosulfonic acid, i-perchlorate, njll.
I-Acetonitrile Chromatographic analysis of reference materials. Ingasetshenziswa njengoketshezi oluncibilikayo nolumile lwe-high pressure liquid chromatography (HPLC). Izincibilikisi zamakhompawundi amaningi wezinto ezingaphili, izincibilikisi ze-spectrophotometric nezingezona amanzi. Isetshenziswa njenge-diluent lapho kunqunywa iqembu le-carboxyl. I-recrystallization ye-steroids, ukukhishwa kwama-fatty acids, njll.
I-Chemwin ingahlinzeka ngenqwaba yama-hydrocarbon amaningi nezincibilikisi zamakhemikhali kumakhasimende ezimboni.Ngaphambi kwalokho, sicela ufunde ulwazi olulandelayo oluyisisekelo mayelana nokwenza ibhizinisi nathi:
1. Ezokuphepha
Ukuphepha kuyinto ehamba phambili yethu. Ngaphezu kokunikeza amakhasimende ulwazi mayelana nokusetshenziswa okuphephile nokunobungani kwemvelo kwemikhiqizo yethu, siphinde sizibophezele ekuqinisekiseni ukuthi ubungozi bokuphepha kwabasebenzi nosonkontileka buncishiswa bube buncane obunengqondo nobunokwenzeka. Ngakho-ke, sidinga ikhasimende ukuthi liqinisekise ukuthi izindinganiso ezifanele zokuphepha zokuthulula nokugcinwa kwempahla ziyahlangatshezwa ngaphambi kokulethwa kwethu (sicela ubhekisele kusithasiselo se-HSSE emigomeni nemibandela evamile yokuthengisa ngezansi). Ochwepheshe bethu be-HSSE banganikeza isiqondiso kulawa mazinga.
2. Indlela yokulethwa
Amakhasimende anga-oda futhi alethe imikhiqizo evela ku-chemwin, noma angathola imikhiqizo evela embonini yethu yokukhiqiza. Izindlela zokuthutha ezitholakalayo zifaka phakathi iloli, ujantshi noma ezokuthutha ezinezinhlobo eziningi (kuyasebenza izimo ezihlukene).
Endabeni yezidingo zekhasimende, singacacisa izidingo zezikebhe noma amathangi futhi sisebenzise amazinga akhethekile okuphepha/wokubuyekeza kanye nezimfuneko.
3. Inani elincane le-oda
Uma uthenga imikhiqizo kuwebhusayithi yethu, inani elincane le-oda amathani angama-30.
4.Inkokhelo
Indlela yokukhokha ejwayelekile idonswa ngokuqondile zingakapheli izinsuku ezingu-30 ukusuka ku-invoyisi.
5. Amadokhumenti okulethwa
Amadokhumenti alandelayo anikezwa ngokudiliva ngakunye:
· I-Bill of Lading, i-CMR Waybill noma enye incwadi yezokuthutha efanele
· Isitifiketi Sokuhlaziya noma Ukuvumelana (uma sidingeka)
· Imibhalo ehlobene ne-HSSE ngokuhambisana nemithethonqubo
· Imibhalo yeCustoms ngokuhambisana nemithethonqubo (uma kudingeka)
