E leai ni lanu manino po'o se vai samasama mumu ma le manogi i'a

1. O se solvent organic sili ona lelei, faʻaaogaina e fai ma solvent mo polyurethane, polyacrylonitrile, ma le polyvinyl chloride.E fa'aaogaina fo'i e fai ma meafaitino mo su'ega, vaila'au ma vailaau fa'asaina.

2. Faʻaaogaina e fai ma suʻesuʻega suʻesuʻe ma solvent mo vinyl resin ma acetylene

3. O le Dimethylformamide e le gata o se vailaʻau faʻamaʻi sili ona lelei, ae faʻapea foʻi ma se soli sili ona lelei.Dimethylformamide o se solvent lelei mo le tele o polymers e pei o le polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, ma isi, ma e mafai ona faʻaaogaina mo le susu viliina o alava gaosia e pei o le polyacrylonitrile fiber, ma le faʻaogaina o le polyurethane;Fa'aaogaina i le faia o ata palasitika;e mafai foʻi ona faʻaaogaina e fai ma aveese vali e aveese ai le vali;e mafai foʻi ona faʻamavaeina nisi o lanu e maualalo, e tuʻuina atu i pigments uiga o vali.Dimethylformamide o loʻo faʻaaogaina mo le faʻaaogaina o mea manogi ma le vavaeeseina ma le toe faʻaleleia o le butadiene mai le vaega C4 ma le isoprene mai le vaega C5.E mafai fo'i ona fa'aaogaina e fai ma mea fa'afoliga lelei mo le tu'u'ese'ese o vaega e le o le hydrocarbon mai le paraffin..E lelei le filifilia i le solubility o le isophthalic acid ma le terephthalic acid: o le solubility o le isophthalic acid i le dimethylformamide e sili atu nai lo le terephthalic acid.Ole tusi ole vaila'au e fa'atino le su'eina ole solvent po'o le fa'ama'a'ai fa'apitoa e mafai ona tu'u'ese'ese ai le lua.I totonu o fale gaosi oloa, o le dimethylformamide e mafai ona faʻaaogaina e avea o se kesi e faʻafefe e vavae ma faʻamamaina le kesi.I gaioiga faʻasolosolo, o le dimethylformamide e le gata o loʻo faʻaaogaina lautele e avea o se solvent mo le tali, ae o se mea taua tele i le synthesis organic.I totonu o fale gaosi oloa, e mafai ona faʻaaogaina e gaosia ai iniseti;i le falemaʻi vailaʻau, e mafai ona faʻaaogaina e faʻapipiʻi ai iodosamine, doxycycline, cortisone, vitamini B6, iodoside, ququjing, pyrantel, N-formyllysar Onumaric acid, methoxy sinapi, chlorambucil, nitrosourea, furfurouracil, tranexamic acid, fentrolmethasonecho, fentrolmethasone chlorpheniramine, ma isi. Dimethylformamide o loʻo i ai se aʻafiaga faʻapitoa i gaioiga o le hydrogenation, dehydrogenation, dehydration ma le dehydrohalogenation, lea e faʻaitiitia ai le vevela o le tali ma faʻaleleia le mama o le oloa.

4.Titration o solvents le-aqueous.Solvent mo vinyl resin ma acetylene.Fuafuaga photometric.Gas chromatographic vai tumau (maualuga le faaaogaina o le vevela 50 ℃, solvent o le methanol), eseese Chemicalbook e iloilo C2-C5 hydrocarbons, ma e mafai ona tuueseeseina masani ma isobutene ma cis ma trans-2-butene.Su'esu'ega o toega o vailaau fa'asaina.Fa'asoa fa'aletino.Fa'asologa o peptides.Mo le fale pueata.
