Pyrrolidone 616-45-5

Synthesis thiab ntau lawm txheej txheem

Tom qab xyoo ntawm txoj kev loj hlob, kev lag luam kev lag luam thev naus laus zis ntawm 2-pyrrolidone tau paub tab thiab muaj txiaj ntsig. Feem ntau muaj cov txheej txheem synthesis hauv qab no:

Succinic anhydride txoj kev

Cov txheej txheem ntws: Succinic anhydride reacts nrog ammonia los tsim butyrolactam, thiab 2-pyrrolidone yog tau los ntawm catalytic hydrolysis thiab cyclization.

Nta: Cov khoom siv raw yog qhov dav thiab cov txheej txheem yog qhov yooj yim, tab sis muaj qee qhov kev sib tw hauv kev tswj los ntawm cov khoom thiab kev kho dej khib nyiab.

Txoj kev acetonitrile-ethylene ketone

Cov txheej txheem ntws: Acetonitrile thiab ethylene ketone hnov ​​​​mob nrog cov catalyst los tsim cov qauv qhib lub nplhaib thiab tom qab ntawd cyclize rau daim ntawv 2-pyrrolidone.

Nta: Cov tshuaj tiv thaiv me me thiab kev xaiv siab, tab sis kev tsim khoom thiab khaws cia ntawm ethylene ketone siab.

Biological fermentation txoj kev

Cov txheej txheem khiav: Siv microbial metabolism los hloov biomass xws li succinic acid rau hauv 2-pyrrolidone.

Nta: Ntsuab thiab ib puag ncig tus phooj ywg, ob peb los ntawm cov khoom lag luam, thiab maj mam paub txog kev lag luam, tab sis tam sim no tus nqi kuj tseem siab.

IV. Cov chaw siv tseem ceeb

1. Cov kuab tshuaj

2-pyrrolidone yog dav siv los ua ib qho hnyav hnyav vim nws cov solubility zoo thiab ruaj khov:

Inkjet luam ntawv number case: Raws li cov kuab tshuaj tseem ceeb, 2-pyrrolidone tuaj yeem txhim kho fluidity, adhesion thiab stability ntawm tus number case, thaum tseem muaj qhov tsis zoo, txo qhov cuam tshuam rau ib puag ncig thaum lub sijhawm luam ntawv.

Coatings thiab adhesives: siv los yaj cov ntaub ntawv polymer xws li polyurethane thiab polyvinyl chloride los txhim kho cov cuab yeej ua yeeb yaj kiab thiab adhesion ntawm txheej.

Tus neeg saib xyuas hluav taws xob: Hauv kev tu cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob zoo, 2-pyrrolidone tuaj yeem tshem tawm cov av zoo yam tsis muaj kev puas tsuaj rau lub substrate.

2-Pyrrolidone nws tus kheej yog siv nyob rau hauv lub tshuab luam ntawv cartridges].

Qee cov tshuaj yog derivatives ntawm 2-pyrrolidone, xws li cotinine, doxapram, polyvinylpyrrolidone, ethosuximide thiab piracetam.

2-Pyrrolidone yog ib qho nruab nrab hauv kev tsim cov vinylpyrrolidone, ua ntej ntawm polyvinylpyrrolidone, thiab cov kuab tshuaj NMP.
