acetonitrile (cas 75 05 8) puas yuav yaj cov yas?
Acetonitrile reacts nrog cov oxidants muaj zog xws li nitric acid, chromic acid thiab sodium peroxide, ua rau hluav taws kub thiab tawg txaus ntshai. Acetonitrile tsim cov pa phem ntawm hydrogen cyanide thiab nitrogen oxides ntawm combustion. Nws tawm tsam qee hom yas, roj hmab thiab txheej txheej.
Puas yog acetonitrile corrosive?
HPLC qib acetonitrile tau pom tias nws tuaj yeem ua rau muaj kev sib kis ion thiab corrosion ntawm 316 stainless hlau thiab C-22 Hastelloy sintered hlau discs.
Dab tsi yog qhov tsis zoo ntawm acetonitrile?
Acetonitrile tau yooj yim ignited los ntawm tshav kub, sparks los yog nplaim taws thiab muab cov pa phem heev hydrogen cyanide fumes thaum rhuab. Nws dissolves yooj yim hauv dej. Nws tuaj yeem hnov mob nrog dej, chav dej lossis cov kua qaub los tsim cov vapors uas tuaj yeem tsim cov khoom tawg thaum raug huab cua.
Kev siv acetonitrile
Acetonitrile los yog methyl cyanide yog ib qho muaj zog heev, aprotic polar organic hnyav.
Acetonitrile (CAS 75-05-8), raws li ib tug polar organic solvent, muaj ntau daim ntawv thov. Hauv qab no yog ob peb qhov chaw siv ntau yam:
Tshuaj Synthesis
Acetonitrile ua haujlwm raws li cov kuab tshuaj thiab lub cev qhuav dej hauv ntau cov organic synthesis tshwm sim.
Pharmaceuticals
Acetonitrile yog cov kuab tshuaj siv dav hauv kev lag luam tshuaj, ua haujlwm hauv kev tsim tshuaj tua kab mob, tshuaj hormones, vitamins, tshuaj intermediates, thiab lwm yam.
Kev kho mob hlau
Thaum lub sij hawm ua cov hlau nto, acetonitrile cov ntaub ntawv complexes nrog impurity ions nyob rau hauv cov hlau, yooj yim tshem tawm cov kab mob thiab cov pa phem.
Lwm Daim Ntawv Thov
Acetonitrile kuj tseem ua cov kuab tshuaj lossis cov tshuaj tiv thaiv nruab nrab rau dyes, coatings, plastics, rubber, textiles, thiab ntau dua. Tsis tas li ntawd, nws yog siv rau cov qauv pretreatment hauv kev ntsuas ntsuas xws li roj chromatography, NMR, thiab infrared spectroscopy.
Acetonitrile Storage
Acetonitrile Storage Guidelines
Cov tshuaj acetonitrileyuav tsum tau muab cia rau hauv cov thawv kaw, kaw kom nruj, khaws cia kom zoo kom tsis txhob muaj cua sov, cov nplaim taws, thiab qhib nplaim taws. Xyuas kom qhov chaw cia yog qhuav, zoo - qhov cua, thiab kom meej meej cais los ntawm cov khoom uas yuav hnov mob nrog acetonitrile, suav nrog:
- Muaj zog oxidizing tus neeg sawv cev
- Muaj zog acids
- Txo cov neeg ua haujlwm
- Bases
Cov thawv ntim khoom yuav tsum tau tshuaj xyuas tsis tu ncua rau cov cim qhia txog kev xau, corrosion, lossis kev puas tsuaj rau lub cev kom ntseeg tau ntev -kev nyab xeeb.
Txhawm rau tiv thaiv cov neeg ua haujlwm thiab chaw ua haujlwm ntxiv, siv cov kev ntsuas kev nyab xeeb hauv qab no:
- Tsis tu ncua tshuaj xyuas thiab hloov kho cov txheej txheem khaws cia raws li xav tau
- Kom meej meej sau tag nrho cov ntim thiab cov chaw khaws cia
- Qhia txhua tus neeg ua haujlwm uas tuaj yeem nkag mus rau thaj chaw khaws cia ntawm kev tuav thiab khaws cia
- Khaws cov ntaub ntawv tseeb ntawm qhov chaw khaws cia thiab cov khoom muag kom muaj nuj nqis
Teb rau Kev Txhaum Cai thiab Leaks
Nyob rau hauv cov xwm txheej uas muaj dej los yog xau, khiav tawm ntawm thaj chaw tam sim ntawd. Raws li acetonitrile yog cov nplaim taws heev, tshem tawm tag nrho cov khoom siv hluav taws xob los tiv thaiv hluav taws los yog tawg.
Xyuas kom muaj qhov cua txaus kom txo tau vapor tsub zuj zuj thiab nqus tau pa. Siv cov ntaub ntawv tsis muaj zog, nqus tau kom muaj cov txeej, thiab ua haujlwm ntxuav tsuas yog nrog cov pa taws - cov cuab yeej pov thawj.
Vim li cas thiaj xaiv Gneebio?
Gneebio, nrog ntau xyoo dhau los ntawm kev tshawb fawb, kev tsim khoom, thiab kev lag luam ntawm cov tshuaj organic, yog ib qho ntawm cov khoom xa tawm ntawm cov khoom siv tshuaj hauv Henan, Suav. Tau ntau xyoo, peb tau cog lus rau kev lag luam tshuaj lom neeg ntawm cov khoom nruab nrab, cov khoom siv yas, cov tshuaj kho dej thiab cov tshuaj fungicides, thiab cov tshuaj niaj hnub.
Qhov zoo
1) Cov khoom xa tuaj me me thiab sub- ntim khoom muaj.
2). Muab COA, MSDS, Daim Ntawv Pov Thawj Kev Noj Qab Haus Huv, thiab Daim Ntawv Pov Thawj Keeb Kwm.
3) Zoo ua ntej, kev pabcuam zoo tshaj plaws.
Nyem qhov no kom tau txais qhov tseeb thoob ntiaj tebAcetonitrile (CAS 75-05-8) cov nqi lag luam rau xyoo 2026.
