Isticmaalka
Mid ka mid ah sifooyinka muuqda ee DMF waa awoodda ay si xor ah ugu qasto biyaha iyo inta badan dareerayaasha organic. Dabeecaddani waxay ka duwan tahay dareerayaasha kale, taasoo ka dhigaysa mid aad u badan oo ku habboon codsiyo kala duwan. DMF waxay soo bandhigtaa milmi heer sare ah oo loogu talagalay isku-dhafka dabiiciga ah iyo kuwa aan noolaha ahayn, taas oo ka dhigaysa shay muhiim ah oo ka mid ah isku-darka daawooyinka, dheeha, iyo polymers. Dabeecaddeeda midab-la'aanta iyo hufnaanta leh waxay hubisaa inaysan ka tagin wax raad ah ama hadhaaga ah, taasoo ka dhigaysa mid ku habboon alaab tayo sare leh oo xasaasi ah.
Badeecadahayada DMF waxaa loo yaqaanaa ma aha oo kaliya sifooyinkooda dareeraha, laakiin sidoo kale tayada gaarka ah. Waxaan ku hanweynahay inaan bixinno DMF-yo tayo sare leh oo buuxiya heerarka warshadaha ugu sarreeya. Nadiifinteeda iyo joogtaynteeda ayaa ka dhigaysa doorasho lagu kalsoonaan karo oo loogu talagalay xirfadlayaasha goob kasta. Laga soo bilaabo soosaarayaasha dawooyinka ilaa soosaarayaasha kiimikada, DMF-yadayadu waxay caan ku yihiin isku halaynta iyo waxqabadkooda.
Marka la soo koobo, N,N-Dimethylformamide-keena waa badeecad qaali ah oo leh tayo iyo tayo aan la barbar dhigi karin. Iyada oo ay ku milmayn heer sare ah oo kala duwan oo ka mid ah xeryahooda iyo awoodda ay u leedahay in ay ku daraan biyaha iyo dareerayaasha organic, waa alaabta ceeriin ee ugu dambeysa ee kiimikaad ee warshado badan. Haddii aad u baahan tahay dareerayaasha isku-darka dawooyinka, wax-soo-saarka dheeha ama wax-soo-saarka polymer, DMF-yadayadu waxay xaqiijinayaan heerarka ugu sarreeya ee waxqabadka iyo isku halaynta. Aamin alaabtayada si ay u buuxiyaan shuruudahaaga oo aad u qaaddo hawlgalladaada meel sare.
