1-Methyl-2-pyrrolidinone, nws tus lej sau npe yog 872-50-4. Nws kuj tseem hu ua N-Methyl-2-pyrrolidinone; N-Methyl-2-Pyrrolidone; NMP; thiab N-Methylpyrrolidone. Nws muaj kev phom sij, yog li cov kev ntsuas kev pab thawj zaug thiab lwm yam yuav tsum paub. Tsis tas li ntawd, N-methyl-pyrrolidone (CAS NO.872-50-4) tuaj yeem ruaj khov ntawm chav tsev kub hauv cov thawv kaw hauv qab qhov chaw khaws cia thiab tuav ib txwm muaj. Nws tsis sib xws nrog cov neeg sawv cev oxidizing muaj zog, cov kua qaub muaj zog, cov hauv paus muaj zog, thiab koj yuav tsum tsis txhob noj nws nrog cov ntaub ntawv tsis sib xws, lub teeb, qhov kub siab tshaj 100 ° C, raug rau huab cua ntub lossis dej. Thiab tseem tiv thaiv nws kom tawg mus rau hauv cov khoom puas tsuaj: nitrogen oxides, carbon monoxide, carbon dioxide.

Cov khoom siv lub cev txog 1-Methyl-2-pyrrolidinone yog: (1) ACD/LogP: -0.637; (2) ACD/LogD (pH 5.5): -0.64; (3) ACD/LogD (pH 7.4): -0.64; (4) ACD/BCF (pH 5.5): 1.00; (5) ACD/BCF (pH 7.4): 1.00; (6) ACD/KOC (pH 5.5): 10.73; (7) ACD/KOC (pH 7.4): 10.73; (8) #H bond acceptors: 2; (9) Index of Refraction: 1.47; (10) Molar Refractivity: 26.852 cm³(11) Molar Ntim: 96.268 cm³(12) Kev sib hloov pauv: 10.645 10-24cm³(13) Kev Ntshaw Nto: 33.7919998168945 dyne/cm; (14) Qhov Ceev: 1.03 g/cm³; (15) Lub Cim Qhia Teeb Meem: 86.111 °C; (16) Lub Cim Qhia Txog Kev Ua Pa: 43.821 kJ/mol; (17) Lub Cim Qhia Kub: 201.999 °C ntawm 760 mmHg; (18) Lub Cim Qhia Pa: 0.29899999499321 mmHg ntawm 25°C

Kev npaj ntawm 1-Methyl-2-pyrrolidinone: 1-Methyl-2-pyrrolidinone (CAS NO.872-50-4) tuaj yeem muab tau los ntawm cov tshuaj tiv thaiv ntawm Γ-butyrolactone nrog amine.

Kev Siv 1-Methyl-2-pyrrolidinone: 1-Methyl-2-pyrrolidinone yog siv ua cov khoom siv nruab nrab rau kev tsim cov tshuaj, agrochemicals, plasticizers, textile auxiliaries, stabilizers. Nws kuj tseem siv dav hauv kev ua roj refining, pigments thiab ntxuav, high polymer synthesis, tshuaj, cov ntaub ntawv rwb thaiv tsev, thiab lwm yam.

Thaum koj siv cov tshuaj no, thov ceev faj txog nws raws li cov hauv qab no:
1. Yog muaj hluav taws thiab/lossis tawg, tsis txhob ua pa cov pa phem.
2. Yog tias muaj xwm txheej lossis koj xav tias koj tsis zoo, nrhiav kev pab kho mob tam sim ntawd (qhia daim ntawv lo rau qhov twg ua tau)
3. Tsis txhob raug kev phom sij - nrhiav kev qhia tshwj xeeb ua ntej siv

Koj tseem tuaj yeem hloov cov ntaub ntawv hauv qab no mus rau hauv cov qauv molecular:
