1 Methyl 2 Pyrrolidone 616-45-5

2-Pyrrolidone, CAS No. 616-45-5, yog cov xim tsis muaj xim rau daj ntseg daj kua lossis siv lead ua, thiab yog qhov yooj yim tshaj plaws -lactam. Nws yog cov kua uas tsis muaj xim uas yog miscible nrog dej thiab feem ntau cov organic solvents.

Cov khoom siv tshuaj

2-Pyrrolidone tsim hlau ntsev nrog alkali hlau, hlau hydroxides lossis alkaline hydroxides. Nws tuaj yeem hydrolyzed nyob rau hauv muaj cov kua qaub uas muaj zog los tsim 4-aminobutyric acid. Nws reacts nrog acetic anhydride los tsim N-acetyl pyrrolidone. Nws reacts nrog paraformaldehyde hauv qab catalysis kom tau N-hydroxymethyl-2-pyrrolidone.

Hais txog kev solubility, 2-pyrrolidone tuaj yeem tov nrog dej, cawv, thiab ether. Nws yog miscible nrog feem ntau lub teeb-rhiab hnyav hnyav xws li benzene, ethyl acetate thiab carbon disulfide, thiab nyuaj rau yaj hauv roj av ether.

2-Pyrrolidone thiab nws cov derivatives muaj ntau yam kev lag luam siv.

2-Pyrrolidone yog siv los ua cov kuab tshuaj rau cov khoom siv hluavtaws, plasticizers, polymerizers, inks, tshuaj tua kab, tshuaj tua kab, polyols thiab iodine, thiab tseem yog cov organic synthesis nruab nrab. Nws yog siv los ua nylon 4 thiab polyvinyl pyrrolidone, nylon 4 thiab raw khoom rau naofukang.

Txoj kev npaj

Nws yog feem ntau tau los ntawm amination ntawm -butyrolactone. Lwm txoj hauv kev yog siv cov txiv neej anhydride ua cov khoom siv raw, hydrogenate thiab amination, thiab cov txiaj ntsig tuaj yeem ncav cuag 90% -92%.

Kev khaws cia thiab kev nyab xeeb

Cia: Nws yuav tsum qhuav, qhov cua, kom deb ntawm hluav taws thiab lwm yam khoom txaus ntshai, thiab tsis txhob raug tshav ntuj ncaj qha.

Kev thauj mus los: Thaum lub sij hawm thauj mus los, xyuas kom meej tias lub thawv tsis xau, tawg, poob lossis puas. Qhov kub ntawm cov khoom nyob rau hauv lub tank tsheb yuav tsum khaws cia tsis pub tsawg tshaj 25 degree los pab txhawb nqa thiab unloading. Nws yuav tsum tau thauj khoom thiab tshem tawm maj mam thaum thauj mus los kom tsis txhob muaj kev puas tsuaj rau lub thawv ntim khoom. Nws yog txwv tsis pub sib xyaw nrog cov khoom lom thiab corrosive. Thaum lub sij hawm kev thauj mus los, nws yuav tsum tau tiv thaiv los ntawm tshav ntuj thiab nag, thiab kom deb ntawm hluav taws kub, qhov chaw kub thiab qhov kub thiab txias.
