Txoj kev tsim khoom

Muaj ntau txoj hauv kev los ua acetonitrile. Cov kev tseem ceeb rau kev tsim khoom muaj xws li acetate amination method, acetylene amination method thiab propylene ammoxidation byproduct method.

1. Acetate amination method siv acetate thiab ammonia ua raw cov ntaub ntawv nrog cov tshuaj tiv thaiv tau ua nyob rau ntawm qhov kub ntawm 360-420 degree nyob rau hauv lub xub ntiag ntawm txhuas oxide raws li catalyst. Qhov no yog ib kauj ruam synthesis. Cov tshuaj tiv thaiv kev sib xyaw yog ntxiv mus los ntawm kev nqus dej thiab kev ua kom zoo distillation kom tau txais cov khoom kawg. Cov khoom siv kom muaj nuj nqis: acetate (98%) 1763kg / t, ammonia (99.5%) 691kg / t.

2. Cov txheej txheem Acetylene amination siv ammonia thiab acetylene raws li cov ntaub ntawv raw thiab cov tshuaj tiv thaiv yog nqa tawm ntawm qhov kub ntawm 500-600 degree nrog aluminium oxide ua tus catalyst. Nws yog dua ib-kauj ruam synthesis mus kom ze. Cov khoom siv kom muaj nuj nqis: acetylene 10231 m3, ammonia (99.4 feem pua) 1007 kg / t.

3. Propylene amination thiab oxidation byproduct method siv propylene, ammonia, thiab cua ua cov khoom siv raw. Nws tsim acrylonitrile nrog cov catalyst thaum tsim acetonitrile raws li cov khoom lag luam. Ib tuj ntawm acrylonitrile tuaj yeem ua tau 25-100kg byproduct ntawm acetonitrile.

4. Ua los ntawm lub cev qhuav dej cov tshuaj tiv thaiv ntawm acetamide thiab phosphorus pentoxide.

5. Tau los ntawm cov tshuaj tiv thaiv ntawm dimethyl sulfate thiab sodium cyanide.

Acetonitrile feem ntau yog cov byproduct ntawm ammoxidation cov tshuaj tiv thaiv siv los ua acrylonitrile. Peb kuj tuaj yeem siv txoj kev acetate amination nrog txhuas oxide ua tus catalyst. Acetonitrile yog tau los ntawm ib kauj ruam cov tshuaj tiv thaiv ntawm 360 degree.

Reaction equation: CH3COOH plus NH3 [Al2O3] → CH3CN plus 2H2O.

Khoom siv

1. Acetonitrile tuaj yeem siv los ua cov organic hloov thiab hnyav rau nyias txheej chromatography, ntawv chromatography, spectroscopy thiab polarographic tsom xam.

2. Acetonitrile yog cov kuab tshuaj siv dav, feem ntau yog siv los ua cov kuab tshuaj rau extractive distillation.

3. Acetonitrile tuaj yeem siv los ua cov tshuaj intermediates ntawm ntau yam tshuaj thiab tshuaj tua kab.

4. Acetonitrile yog cov kuab tshuaj organic uas muaj zog polarity, uas muaj cov zoo solubility rau roj, inorganic ntsev, organic tshuaj thiab polymer tebchaw.

5. Acetonitrile kuj tseem siv rau hauv cov ntaub dyeing thiab txheej txheej, thiab nws kuj yog ib qho zoo stabilizer rau cov kuab tshuaj chlorinated.
