Dab tsi yog DMF cov kuab tshuaj?
Dimethylformamide (DMF) yog qhov tseeb, muaj xim tsis muaj kob, kua nrog me ntsis amine tsw. Cov Khoom Siv Solvent ntawm DMF tau ntxim nyiam tshwj xeeb vim tias lub dielticric constant, lub suab nrov ntawm cov kuab tshuaj, nws cov kua ntau thiab tsis muaj zog. Nws yog nquag siv rau tshuaj lom neeg cov tshuaj lom neeg thiab lwm yam kev siv, uas xav tau lub zog siab. Cov khoom yog lub npe hu ua ib lub dav hlau universal.
Dab tsi yog thf huab tais?
TetrahyDrofuran (THF) yog qhov tseeb, tsis muaj kob, organic sib xyaw nrog lub {{}} zoo li tsw thiab cov mis (CH2) 4O. Nws yog feem ntau siv los ua ib tug precursor rau cov polymers suav nrog txheej saum npoo, cov nplaum, thiab cov ntawv luam tawm. Nws yog dej - ua kom tsis meej thiab muaj qhov tsis muaj viscosity ua rau nws muaj ntau yam hnyav siv siv ntau yam kev lag luam.
Dab tsi yog qhov txawv ntawm DMF thiab thf huab tais?
| Yam zoo | Tetrahydrofuran (thf) | Dimethylformamide (DMF) |
|---|---|---|
| Cov Qauv Tshuaj | Cyclic Ethere (C₄h₈o) | Amide (HCON (CHO) ₂) |
| Thaj yeeb | Tus ncej | Zoo heev polar |
| Qhov tseem ceeb Cov Khoom Siv Hluav Taws Xob | Zoo heev rau orgongometallics (grignard), zoo rau tsis - recounds. | Zoo heev rau cov ncej puab polar, polymers, thiab sn2 cov tshuaj tiv thaiv. |
| Thawj siv | Polymerization hnyav, PVC Maas, Grignard kev tawm tsam. | Kuab rau polyacrylonitrile (acrylic fibers), acrylics, thiab peptide synthesis. |
| Kev ua txhaum nrog dej | Tag nrho tsis meej | Tag nrho tsis meej |
| Kev phom sij | Cov nplaim, cov qauv tawg ua ke. | Tsawg cov nplaim taws, tab sis muaj kev ua me nyuam taug txuj lom thiab tuaj yeem nqus tau los ntawm daim tawv nqaij. |
Qhov twg yuav tetrahydrofuran thf huab hwm?
