CAS6 {-} 05-8 Acetonitrile yog ib cov organic huab hwm los ntawm nws cov hniav tsis muaj ntsej muag thiab cov tshuaj lom tsawg. Nws muaj qhov txawv txav tsis hnov tsw, tsis muaj kua yeeb yam, thiab lub siab npau npau. Nws yog dav siv los ua tshuaj lom neeg nyob rau hauv kev tsim cov kws tshuaj paus, agnchemicals, dyes, plastics, thiab lwm yam ntaub ntawv.
Kua Acetonitrile siv
Kaus: Acetonitrile yog cov kuab tshuaj zoo rau ntau cov organic thiab yog tsim tshwj xeeb rau cov organic synthesis, thiab kev tshawb fawb txog kev tshawb fawb. Nws tuaj yeem yaj ntau cov organic sib xyaw, xws li dej cawv, ketones, acids, thiab halogenated sib txuas.
Chromatographic tsom xam: acetonitrile yog qhov dav dav siv raws li lub sijhawm mobile hauv cov kua chromatography. Nws tuaj yeem sib cuam tshuam tau zoo nrog ntau cov sib xyaw, muab kev sib cais ua tau zoo thiab pom rau cov hom phiaj ntsuas.
Kev Tshawb Fawb Hauv Electrochemical: Acetonitrile yog ib feem siv cov kuab nyob hauv cov kev sim electrochemical. Nws cov khoom pov thawj kev ruaj ntseg thiab tsis muaj txiaj ntsig zoo, ua rau nws cov kev tshawb fawb thiab cov kev cai ntawm electrochemical.
Kws Tshuaj Kho Mob: Cov Acetoniturile yog siv los ua nruab nrab thiab cov kuab tshuaj hauv kev lag luam kws tshuaj. Nws yog dav dav nyob rau hauv cov tshuaj siv tshuaj thiab tshuaj tua kab mob, xws li vitamin b1 thiab vitamin A.
Lwm yam kev siv: acetoniturile tseem siv los ua cov kuab tshuaj thiab sab hauv cov roj chromatography}}} huab cua spectrometry tsom, nrog rau catalyst nyob rau qee yam tshuaj lom neeg.
Synthesis txoj kev ntawm Acetonitrile Kua:
- Ethylene cyanide yog tsim los ntawm kev rov ua kom ethylene nrog sodium lossis poov xab hauv qab kub thiab siab.
- Ethanol lub cev qhuav dej: acetonitrile yog tsim los ntawm kev rov ua kom ethanol nrog concentrated sulfuric acid (lossis phosphoric acid).
- Propanonitrile Hydrolysis: propanonitrile yog hydrolyzed nrog cov kua qaub lossis hauv paus los tsim cov acetonitrile.
- Formamide Hydrolysis: Formamide tau hnov nrog ammonia los tsim cov acetonitrile los ntawm kev tshaj tawm.
