Dimethylformamide (soo gaabinta DMF), oo sidoo kale loo yaqaan N, N-dimethylformamide, waa beddelka dimethyl ee foramide, iyo labada kooxood ee methyl waxay ku yaalaan atamka N (nitrogen), sidaas darteed waa magac. Maaddaama ay tahay walxo kiimiko ah oo muhiim ah iyo dareere aad u fiican, DMF waxaa si weyn loogu isticmaalaa polyurethane, acrylic, waxyaabaha lagu daro cuntada, daawada, sunta cayayaanka, dheeha, elektiroonigga iyo warshadaha kale.

DMF waa dareere aan midab lahayn oo hufan oo leh bar karsan oo sarreeya, barta qabowgu hooseeyo, degganaansho kiimiko iyo kulayl wanaagsan, waana dareere aan lahayn biyo iyo inta badan dareerayaasha organic. Waa dareere caadi ahaan loo isticmaalo falcelinta kiimikaad waxaana loo yaqaannaa "qalal caalami ah": DMF waxaa loo isticmaalaa Fiber acrylic ee ay soo saarto habka qallalan ee qalalan ee fiilada akril ee dareeraha ku salaysan waxay leedahay sifooyinka hydrophobicity wanaagsan, awood daboolan oo xooggan, jilicsanaan jilicsan, iyo gacanta xoogga leh; Soo saarista maqaarka polyester-ka ee qoyan, DMF waxaa loo isticmaali karaa sidii wax lagu dhaqo oo lagu daweeyo resin polyurethane. Waxaa loo isticmaalaa in lagu daboolo walxo kala duwan oo la faafin karo, iyo marka loo isticmaalo dheeha maqaarka, waxay ka dhigi kartaa midabka lebbiska maqaarka oo aan dhicin; Awooddeeda adag awgeed, DMF waxaa loo isticmaalaa sida dareeraha dheeha waxaana loo isticmaalaa midabaynta fiilooyinka synthetic, taas oo hagaajin karta isku-duubnaanta maqaarka. Guryaha midabaynta; sida dareere door ah oo loo isticmaalo hababka kala-soocidda, DMF waxaa loo isticmaali karaa nuugista kala duwan ee hydrocarbons iyo gaaska aan noolaha ahayn. Tusaale ahaan, DMF waxaa loo isticmaalaa in lagu dhaqo ethylene si looga saaro acetylene, si loo nadiifiyo ethylene. DMF sidoo kale waxaa loo isticmaali karaa in laga soo saaro isoprene, piperylene, iwm. laga soo saaro gaaska qiiqa ee wax soo saarka warshadda ethylene ee isku dhafka ah ee resin unsaturated; DMF waxa kale oo loo isticmaali karaa sida dareere door ah oo loogu talagalay hababka soo saarista ee goobta farsamaynta batroolka. Tusaale ahaan: nidaamyada polycarboxylic acid ee leh sifooyin isku mid ah oo ay adag tahay in la kala saaro, sida isophthalic acid iyo terephthalic acid, si fudud ayaa loo kala saari karaa soo saarista dareeraha DMF ama dib-u-crystallization tallaabo tallaabo ah.

Dareen-celinta dabiiciga ah, dimethylformamide ma aha oo kaliya si ballaaran loo isticmaalo sida dareeraha falcelinta, laakiin sidoo kale dhexdhexaad muhiim ah oo ku saabsan isku-darka organic. Warshadaha dawooyinka, sida dhexdhexaadinta daawada synthetic, waxaa si weyn loogu isticmaalaa soo saarista daawooyinka doxycycline, cortisone, iyo sulfonamide; warshadaha cayayaanka, waxaa loo isticmaalaa in lagu soo saaro waxtarka sare leh iyo sunta sunta ah ee hooseeysa iyo cayayaanka.

Sida dhexdhexaadinta falcelinta kiimikada, DMF waxaa loo isticmaali karaa sida dareere crystallization sifaynta daawooyinka. Warshadaha elektiroonigga ah, waxaa loo isticmaali karaa in lagu hagaajiyo viscosity ee wakiilka daawaynta ee laminates clad naxaas ah. DMF waxa kale oo loo isticmaali karaa dareere side si loo sameeyo kareem polymeric leh BF3 (boron trifluoride), samaynta BF3 ka beddelka gaaska una beddesho mid adag oo sahlan in la qaado. Sida dareere aprotic ah (hydrophilic) oo leh barta karkarinta sare, waxay kor u qaadi kartaa falcelinta beddelka nucleophilic ee bimolecular (SN₂). Intaa waxaa dheer, dimethylformamide waxay leedahay saameyn catalytic ee hydrogenation, fuuq-baxa, fuuq-baxa iyo falcelinta fuuq-baxa, taas oo yaraynaysa heerkulka falcelinta waxayna hagaajinaysaa nadiifnimada alaabta.

Waxay u muuqataa in DMF ay u qalanto cinwaanka "qalal caalami ah". Isticmaalkan kala duwan ayaa adkaan doona in lagu dhaafo waqti gaaban gudaheed.
