DMF yog cov kuab tshuaj organic uas yog hygroscopic hauv xwm. DMF tag nrho daim ntawv yog dimethylformamide. Nws yog cov kua tsis muaj kob uas sib tov nrog dej thiab lwm yam kuab tshuaj organic. Nws yog dav siv los ua cov kuab tshuaj hauv cov txheej txheem tshuaj lom neeg. Nws yog cov formic acid amide derivative ntawm formamide. DMF yog polar istictic sakvent li dmf boiling point yog siab ntawm 153 degree. Nws pab txhawb rau kev them nqi ntawm Sn2 kev tawm tsam. DMF cov kuab tshuaj yog pom zoo rau kev tsim cov acrylic fibers.
Lub hom phiaj ntawm DMF hnyav li cas?
Dimethylformamide DMF cov kuab tshuaj nkawj ntau cov organic, organometallic, thiab bioorganic kev hloov pauv.
Kev tsim thiab kev ua cov polymers yog qhov tseem ceeb siv. DMF cov kuab tshuaj yog ua hauj lwm hauv kev tsim cov tawv hluavtaws zoo li kev tig ntawm polyacrylonitrile thiab polyurethane (spandex) fibers.
N, n {- dimetylformamide yog ntxiv siv ntau yam ntawm cov kauj ruam kev tsim tshuaj. DMF qhov kev qhia tshwj xeeb muaj txiaj ntsig tso cai rau nws siv hauv ntau cov kev ua tshuaj ua haujlwm raws li cov tshuaj tiv thaiv thiab crystallising kuab tshuaj.
DMF cov kuab tshuaj yog ntxiv rau hauv ob peb xim pleev xim tshem cov txheej txheem. Txawm li cas los xij, cov teeb meem kev nyab xeeb tiv thaiv nws daim ntawv thov hauv cov khoom siv ntawm cov neeg siv khoom. DMF cov kuab tshuaj muaj zog heev kuj cuam tshuam nws txoj haujlwm ua tus number case thiab zas xim rau hauv ntau cov luam ntawv thiab fiber}}} zas xim siv.
