Ukusetyenziswa kweDimethylacetamide DMAC

I-Dimethylacetamide DMACsisinyibilikisi se-dipolar aprotic esisetyenziselwa ii-organic reactions ezininzi kunye nokusetyenziswa kwemizi-mveliso. Sisinyibilikisi esiguquguqukayo ngenxa yokuba sibila kakhulu kwaye sizinzile kakuhle kubushushu nakwikhemikhali.

1. Iifayibha ze-acrylic
I-Dimethylacetamide DMACIsetyenziswa njengesinyibilikisi kwiinkqubo zokusonta ezimanzi ukuvelisa iifayibha ze-acrylic.
2. Iifayibha ze-Elasthane
Kwimveliso yeefayibha ze-elasthane ezisekwe kwi-polyurethane,I-Dimethylacetamide DMACsisinyibilikisi esikhethwayo xa kujongwa isantya saso sokuphuma kwamanzi, nokuba sisetyenziswa kwiinkqubo zokujikeleza ezimanzi okanye ezomileyo.
3. Amayeza
I-Dimethylacetamide DMACingasetyenziswa njengesinyibilikisi kunye ne-reagent ekuvelisweni kwamayeza ahlukeneyo. Ekuvelisweni kweendaba ezintsha ze-x-ray contrast,I-Dimethylacetamide DMACisetyenziswa njengesinyibilikisi. IiCephalosporins, eziphakathi kwezinye zeendidi eziphambili zee-antibiotics, ziveliswa ngokuyinxenye kwi-7-ADCA (7-aminodeacetoxy-cephalosporanic acid).I-Dimethylacetamide DMACisetyenziswa kwinkqubo yokuvelisa.
4. Iipolima ezahlukeneyo
I-Dimethylacetamide DMACsisinyibilikisi esilungileyo kwiiresini ze-polyimide, kokubini ekugqumeni nasekuveliseni ifilimu. Sikwasisinyibilikisi esifanelekileyo sokwenza iimembrane ze-dialyser, ezisekelwe kwi-polysulfones. Umxube we-DMAC kunye ne-lithium chloride sisinyibilikisi esiluncedo kwiifayibha ze-cellulose kwizicelo ezahlukeneyo.
