ʻO nā waiwai kino e pili ana i ka 1-Methyl-2-pyrrolidinone: (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 nā mea hoʻopaʻa paʻa: 2; (9) Heluhelu o ka Hoʻololi: 1.47; (10) Molar Refractivity: 26.852 knm³; (11) Puke Mola: 96.268 knm³; (12) Polarizability: 10.645 10-24cm³; (13) ʻAʻohe ʻili: 33.7919998168945 dyne/cm; (14) Māmā: 1.03 g/cm³; (15) Lahi Uila: 86.111 °C; (16) Enthalpy o ka hoʻoheheʻe ʻana: 43.821 kJ/mol; (17) Puni paila: 201.999 °C ma 760 mmHg; (18) ʻO ka ʻumehana: 0.29899999499321 mmHg ma 25°C

ʻO ka hoʻomākaukauʻana i ka 1-Methyl-2-pyrrolidinone: 1-Methyl-2-pyrrolidinone (CAS NO.872-50-4) hiki ke loaʻa i ka hopena o ka Γ-butyrolactone me ka amine.

Nā hoʻohana o 1-Methyl-2-pyrrolidinone: 1-Methyl-2-pyrrolidinone hoʻohana ʻia ma ke ʻano he waena no ka synthesis o nā lāʻau lapaʻau, agrochemicals, plasticizers, textile auxiliaries, stabilizers. Hoʻohana nui ʻia ia i ka hoʻomaʻemaʻe ʻana i ka aila, nā puaʻa a me ka hoʻomaʻemaʻe, kiʻekiʻe polymer synthesis, nā kemika, nā mea insulation, etc.

Ke hoʻohana nei ʻoe i kēia kemika, e ʻoluʻolu e makaʻala e like me kēia:
1. Ina he ahi a pahū, mai hanu i ka mahu
2. Inā loa'a ka pō'ino a i 'ole 'oe e 'eha 'oe, e 'imi koke i ka 'ōlelo a'o (e hō'ike i ka lepili inā hiki)
3. Hō'alo i ka 'ike 'ana - e ki'i i ke a'o kūikawā ma mua o ka ho'ohana 'ana
