I-acetonitrile

I-Acetonitrile (i-CAS 75-05-8), eyaziwa nangokuthi i-methyl cyanide, i-cyanomethane, noma i-ACN, iyi-solvent ye-polar aprotic ehlanzekile kakhulu esetshenziswa kakhulu kukhemikhali yokuhlaziya, ukukhiqizwa kwemithi, kanye nokuhlanganiswa kwezinto eziphilayo. Ngefomula ye-molecular CH₃CN kanye nesisindo se-molecular 41.05 g/mol , lolu ketshezi olungenambala, oluguquguqukayo lunikeza amandla angcono kakhulu okuxazulula ububanzi obubanzi bezinhlanganisela ze-polar nezingezona ze-polar.

Izakhiwo Ezibalulekile Zomzimba Nezamakhemikhali

• Ukubukeka : Uketshezi olucacile, olungenambala

• Ubumsulwa : Ngokuvamile ≥99.9% (ibanga le-HPLC/GC liyatholakala)

• Indawo yokubilisa : 81–82°C

• Ukuncibilika : -46 °C kuya ku -44 °C

• Ukuminyana : 0.786 g/mL ku-25 °C

• I-Flash Point : 2 °C (iyavutha kakhulu)

• Ingcindezi Yomhwamuko : ~73 mmHg ku-20 °C

• Inkomba ye-Refractive : n20/D 1.344

• Ukuhlangana Kwamanzi : Kuxubene ngokuphelele

• Iphunga : Okufana ne-ether emaphakathi (umkhawulo wokuthola ~40 ppm)

I-Acetonitrile igqamile ngenxa ye-viscosity yayo ephansi, ukungaguquguquki kwe-dielectric ephezulu, nokungafihli kwe-UV (ukumunca okuphansi okungu-190–230 nm emabangeni ahlanzekile), okuyenza ilungele izicelo ezifunwa kakhulu.

Izicelo Eziyinhloko Nokusetshenziswa

• I-HPLC ne-LC-MS Isigaba Seselula : Okuncanyelwayo okuncamelayo ku-chromatography yoketshezi yesigaba esibuyiselwe emuva ngenxa ye-viscosity ephansi, umumo omuhle kakhulu ophakeme, kanye nokusika kwe-UV okuphansi (~190 nm).

  
  

• I-Pharmaceutical Synthesis and Purification : Isetshenziswa njenge-solvent yokusabela, i-extraction medium, kanye ne-crystallization solvent ekukhiqizeni kwe-API kanye nokuhlanganiswa kwe-peptide.

  
  

• I-Organic Chemistry : I-Polar aprotic solvent yokusabela kwe-nucleophilic, ama-Grignard reagents, kanye nokukhishwa kwamafutha, ama-hydrocarbon, nemikhiqizo yemvelo.

  
  

• I-Analytical Chemistry : Incibilikisa usawoti, i-polar organics, futhi isekela i-spectroscopy, i-electrochemistry, nocwaningo lwebhethri.

  
  

• Izinqubo Zezimboni : Ukukhishwa kwe-Butadiene, ukukhiqizwa kwamakhemikhali okukhethekile, futhi njengento yokuqala yabaphakathi abathile.

  
  

Kungani Khetha I-Acetonitrile Yethu Ehlanzekile Ephakeme?

I-acetonitrile yethu ihlangana noma yeqa i-ACS, USP/NF, kanye ne-Ph. Eur. ukucaciswa kwe-reagent, enokulawula okuqinile phezu kokungcola okufana namanzi (≤0.01% emabangeni aphezulu kakhulu), ubumuncu, nokungcola okumunca i-UV. Ipakishwe ngaphansi kwegesi engasebenzi ukuze kugcinwe ikhwalithi, iqinisekisa imiphumela ephindaphindekayo kuma-gradient ebucayi i-HPLC, i-UHPLC, nama-syntheses azwela umswakama. Itholakala emabangeni ahlukahlukene: Ibanga le-HPLC legradient, ibanga le-LC-MS, i-anhydrous, kanye ne-ultra-high purity.

Ulwazi Lokuphepha Nokuphatha

I-Acetonitrile ihlukaniswa njengoketshezi oluvutha umlilo (Isigaba 2) esinobuthi obunzima ngokuhogela, ukumuncwa kwesikhumba, nokumunca. Bamba ezindaweni ezinomoya omuhle nge-PPE efanele (amagilavu, izibuko, izingubo ezimelana namalangabi). Gcina ezitsheni ezivalwe ngokuqinile ngaphansi kwegesi engasebenzi, kude nemithombo yokuthungela, ku-+5 °C kuya ku-+30 °C. Bheka ku-SDS yakamuva ukuze uthole imihlahlandlela egcwele yengozi nemihlahlandlela yokulahla.

Imibuzo Evame Ukubuzwa (FAQs)

Ithini inombolo ye-CAS ye-acetonitrile?

Inombolo ye-CAS ngu-75-05-8.

Ingabe i-acetonitrile iyafana ne-methyl cyanide?

Yebo, i-acetonitrile (CH₃CN) ivamise ukubizwa nge-methyl cyanide noma i-ethanenitrile.

Kungani i-acetonitrile ikhethwa kune-methanol ku-HPLC?

I-Acetonitrile inikeza i-viscosity ephansi, ukulungiswa okuphezulu okuphezulu, izikhathi ezimfushane zokugijima, nokucindezela okuphansi okubuyela emuva ezinhlelweni zesigaba esihlehlisiwe.

Iliphi ibanga le-acetonitrile elilungele i-LC-MS?

Ibanga le-LC-MS noma i-acetonitrile ye-ultra-high purity enama-ion ensimbi amancane, amanzi, nokungcola okuphilayo kuyanconywa ukuze kuncishiswe umsindo wangemuva nokucindezelwa kwe-ion.

I-acetonitrile kufanele igcinwe kanjani?

Gcina endaweni epholile, eyomile ezitsheni ezivalwe ngci ngaphansi komkhathi ongasebenzi ukuze uvimbele ukumuncwa komswakama kanye nokuwohloka.

Ingabe i-acetonitrile ihlangana ngokuphelele namanzi?

Yebo, i-acetonitrile ixubana ngokuphelele namanzi kanye nezincibilikisi eziningi eziphilayo.

Ukuze uthole izingcaphuno, amashidi edatha yobuchwepheshe, amasampula, noma ama-oda amaningi e-acetonitrile CAS 75-05-8, sicela uthinte ithimba lethu.
