Soosaaraha Qiimaha wanaagsan n, N-Dimethylfyfelinde (DMF) CAS 68-12-2 Sawirka muuqaalka

Sharraxaadda Gaaban:

N, N-Dimethylforfyme ayaa loo soo gaabiyey DMF. Waa xarun ay ka dhasheen badalka kooxda hydroxyl kooxda qaab dhismeedka ah ee ay aashito ah, oo qaaciddada molikaulal waa hcon (ch3) 2. Waa dareere la'aan, hufan, dareere sare oo karkaraya leh ur iftiin iftiin leh iyo cufnaanta qaraabada ee 0.9445 (25 ° C). Meel yar -61 ℃. Karkaraya barta 152.8 ℃. Flash barta 57.78 ℃. Cufnaanta uumiga 2.51. Cadaadiska uumiga 0.49kpa (3.7mmhg25 ℃). Barta gawaarida gawaarida waa 445 ° C. Xadka qaraxa uumiga iyo isku-darka hawada waa 2.2 ilaa 15.2%. Haddii ay dhacdo olol furan iyo kuleyl aad u sareeya, waxay sababi kartaa gubashada iyo qaraxa. Waxay si firfircoon uga falcelin kartaa aashitada ku urursan oo xoog badan oo kacsan oo kacsan nitric acid iyo xitaa qarxi. Waxaa laga karaamayaa biyaha iyo dareeraha dabiiciga ah badankood. Waa xalid guud oo loogu talagalay falcelinta kiimikaad. N, n-Dimethylformadide waa ur la'aan, laakiin fasalka warshadaha ama wax dhaca n, n-dimethylforformformmamud waxay leedahay midab kalluun ah maxaa yeelay waxaa ku jira cilado da 'ah.

sifo

Magaca ayaa ka yimaada xaqiiqda ah in ay tahay bedelka Dimeteyl ee Foomka Moodeel (amisic acid), iyo kooxaha methyl labadaba waxay ku yaalliin atomka n (nitrogen). N, n-Dimethyformyf-ka waa polar-ka sareeya (hydrophilic) (buugga-kiimikada ayaa kor u qaadi karta habka falcelinta SN22. N, n-Dimethylformyfformymid waxaa loo soo saaraa iyadoo la adeegsanayo aashitada qaabeeya iyo Dimmylamine. N, n-Dimethyfformation waa mid aan xasilloonayn (gaar ahaan heerkulka sare) joogitaanka saldhigyo adag sida sodium hydrochloride ama aashito adag sida biyo-hayaha, iyo hyfrolyzes si loo sameeyo acid iyo dimutrololzes. Waa mid aad u deggan hawada iyo markii lagu kululeeyo karkaraya. Markuu heerkulku ka sarreeyo 350 ℃, waxay lumin doontaa biyo waxayna abuuri doontaa kaarboon moono-oksaydh iyo Dimthylamine. N, n-Dimethyformformy-ka waa xalul wanaagsan oo macaan, oo ay ku milmi karaan walxaha dabiiciga ah iyo idaacadda, aalkolada, alayada, guryaha, guryaha lagu hayo, hendrocarbons, iwm. Dhamaadka si togan ee lagu soo oogay ee m, n-dimethylfyflule-ka waxaa ku hareereysan kooxaha methylfy, sameynta caqabad sedex ah, sidaa darteed ilkuhu ma soo dhowaan karaan, laakiin ilmada wanaagsan oo keliya ayaa laxiriira. Anion qaawan ayaa aad uga firfircoon anion xalka ah. Falcelin badan oo ionic ah ayaa si fudud looga fuliyaa n, n-dimethyfformamuun marka loo eego xayndaabka guud ee taxanaha ah, tusaale ahaan, falcelinta kaarbogylates-ka ah hydrocarbons-ka Halogylarbons ee heerkulka qolka, waxay abuuri kartaa edber-ka heer sare ah, gaar ahaan ku habboon Isku-darka esters si daran u caqabad ku ah.

Codsiyada DMF

DMF waa mid wanaagsan oo loogu talagalay polymers noocyo badan oo ka mid ah polyvylne, polyvinyl chloride, polyacryyl, polyamidelonile, polyacryyl, polyamide, oo loo isticmaali karo isgoysyada qallalan sida fiber-ka ee polyacrylonile, iyo isku-darka poranurethane; Waxaa loo isticmaalaa samaynta filimka caagga ah; Waxaa sidoo kale loo isticmaali karaa xarig rinji ah si looga saaro rinjiga; Waxay sidoo kale baabiin kartaa qaar ka mid ah midabka miraha-jilicsan, si midabaduhu ay u leeyihiin astaamaha digaagga. DMF waxaa loo isticmaalaa soosaarka udgoon iyo kala-sooca iyo ka soo kabashada Budadiene ee laga soo bilaabo jajabyada C4 iyo ISOPrene oo laga soo bilaabo jajabyada C5, waxaana sidoo kale loo isticmaali karaa dib-u-soo-celinta qaybaha aan-biyoodka ka soo baxda paraffin. Waxay leedahay xulasho wanaagsan oo lagu xalliyo xaaska asiidhada iyo aashitada tareenka ee loo yaqaan 'Icephalic acid' iyo aashitada qalliinka Warshadaha petrochical, DMF waxaa loo isticmaali karaa gaas sida gaas loo kala saaro oo loo nadiifiyo gaasaska. Iyada oo ah wakiilka dawaynta ee lagu maydho buugga kiimikada ee ku jira warshadaha polyurethethane, waxaa badanaa loo isticmaalaa soo saarista maqaarka maqaarka ee qoyan; Sida dareenka ah ee warshadaha fiber acrylic, waxaa inta badan loo isticmaalaa soosaarka qallalan ee fiber acrylic ah; Warshadaha elektiroonigga ah oo ah mid dhajinaya qaybo yar oo tin-plass ah iyo goleyaal wareega sidoo kale dhexdhexaad ah oo muhiim u ah isku-darka dabiiciga ah.
