DMF: dimethylformamide
DMOs: dimethylsulsulcide
Cov no yog dav siv raws li cov kuab tshuaj.
Dab tsi yog DMF?
Lub sij hawm dmf sawv raudimethyl formamideCov. Nws yog cov organic compound muaj cov mis nyuj (ch3)2NC (o) h. Cov tshuaj no tshwm sim ua cov kua tsis muaj xim uas tsis meej nrog dej thiab feem ntau lwm cov kuab tshuaj muaj organic. Cov kua no kuj tseem siv tau raws li cov kuab tshuaj rau cov tshuaj lom neeg. Qhov no yog vim nws lub ncov qaumteb qabteb.
DMSO li cas?
Lub sij hawm dmo sawv rau Dosethyl Sulfoxide muaj cov mis nyuj (ch3) 2So. Nws tshwm sim ua cov kua tsis muaj kob. Cov kua no yog qhov tseem ceeb rau hauv qab zib polar agory slot farvent uas tuaj yeem yaj ob lub ncov qaumteb qabteb thiab tsis yog cov tebcar thiab tsis sib xws. Tsis tas li, cov kua no yog miscible nrog ntau yam ntawm cov kuab tshuaj organic nrog rau dej. DMOs muaj qhov tseem ceeb boil point. Ntxiv mus, nws muaj ib qho txawv txav ntawm {{7} Zoo li saj hauv lub qhov ncauj tom qab hu rau ntawm daim tawv nqaij.
