Soo-saare Qiimo Fiican N,N-DIMETHYLFORMAMIDE(DMF) CAS 68-12-2

sharraxaad gaaban:

N,N-DIMETHYLFORMAMIDE waxaa loo soo gaabiyaa DMF. Waa isku-dhis ka dhasha beddelka kooxda hydroxyl ee asiidhka formic ee kooxda dimethylamino, qaacidada molecular-kana waa HCON(CH3)2. Waa dareere aan midab lahayn, hufan, oo karkaraya oo leh ur amine khafiif ah iyo cufnaan qaraabo ah oo ah 0.9445 (25°C). Barta dhalaalaysa -61 ℃. Barta karkaraya 152.8 ℃. Barta iftiimaysa 57.78 ℃. Cufnaanta uumiga 2.51. Cadaadiska uumiga 0.49kpa (3.7mmHg25 ℃). Barta shidista otomaatiga ah waa 445°C. Xadka qaraxa ee uumiga iyo isku darka hawada waa 2.2 ilaa 15.2%. Haddii ay dhacdo olol furan iyo kulayl sare, waxay sababi kartaa gubasho iyo qarax. Waxay si xoog leh uga fal celin kartaa asiidhka sulfuric ee xooggan iyo asiidhka nitric oo qiiqaya xitaa way qarxi kartaa. Waa la isku dhex milmi karaa biyaha iyo inta badan dareerayaasha dabiiciga ah. Waa dareere caadi ah oo loogu talagalay falcelinta kiimikada. N,N-DIMETHYLFORMAMIDE saafi ah ma laha ur, laakiin heerka warshadaha ama wasakhaysan N,N-DIMETHYLFORMAMID wuxuu leeyahay ur kalluun ah sababtoo ah waxa ku jira wasakh dimethylamine ah.

sharraxaad

Magacu wuxuu ka yimid xaqiiqda ah inuu yahay beddelka dimethyl ee formamide (amide ee formic acid), labada kooxood ee methyl-na waxay ku yaalliin atomka N (nitrogen). N,N-DIMETHYLFORMAMID waa dareere aprotic ah oo karkaraya (hydrophilic), Chemicalbook-na waxay kor u qaadi kartaa habka falgalka SN2. N,N-DIMETHYLFORMAMID waxaa lagu soo saaraa asiidh formic iyo dimethylamine. N,N-DIMETHYLFORMAMID waa mid aan degganayn (gaar ahaan heerkulka sare) marka ay joogaan saldhigyo xooggan sida sodium hydroxide ama asiidhyo xooggan sida hydrochloric acid ama sulfuric acid, waxayna hydrolyzes u noqotaa formic acid iyo dimethylamine. Aad bay u deggan tahay hawada marka la kululeeyo ilaa la karkariyo. Marka heerkulku ka sarreeyo 350 ℃, waxay waayi doontaa biyaha waxayna soo saari doontaa kaarboon monoksaydh iyo dimethylamine. N,N-DIMETHYLFORMAMID waa dareere wanaagsan oo aprotic polar ah, kaas oo milmi kara inta badan walxaha dabiiciga ah iyo kuwa aan organic ahayn, waana la isku dhex dari karaa biyaha, alkolada, ethers, aldehydes, ketones, esters, halogenated hydrocarbons iyo aromatic hydrocarbons, iwm. Dhammaadka togan ee molecule N,N-DIMETHYLFORMAMID waxaa ku wareegsan kooxo methyl ah, taasoo sameysa caqabad steric ah, si ay ions taban u soo dhowaan karin, laakiin ions togan oo keliya ayaa lala xiriiriyaa. Anion-ka qaawan ayaa aad uga firfircoon anion-ka la milmay. Falgallo badan oo ionic ah ayaa si fudud loogu sameeyaa N,N-DIMETHYLFORMAMID marka loo eego dareerayaasha protic guud ahaan, tusaale ahaan, falcelinta carboxylates oo leh hydrocarbons halogenated ee N,N-DIMETHYLFORMAMID heerkulka qolka, waxay soo saari kartaa esters-ka wax soo saar sare leh, gaar ahaan ku habboon isku-darka esters-ka sterically cakiran.

Codsiyada DMF

DMF waa dareere wanaagsan oo loogu talagalay noocyo kala duwan oo polymers sare ah sida polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, iwm., waxaana loo isticmaali karaa wareejinta qoyan ee fiilooyinka synthetic-ga sida fiilooyinka polyacrylonitrile, iyo isku-darka polyurethane; Waxaa loo isticmaalaa sameynta filimada balaastikada ah; waxaa sidoo kale loo isticmaali karaa sidii xoqe rinji si looga saaro rinjiga; waxay sidoo kale milmi kartaa qaar ka mid ah midabyada milmi kara oo hooseeya, si midabyadu u yeeshaan astaamaha midabaynta. DMF waxaa loo isticmaalaa soo saarista udgoonka iyo kala-soocidda iyo soo kabashada butadiene ee jajabyada C4 iyo isoprene ee jajabyada C5, waxaana sidoo kale loo isticmaali karaa sidii reagent wax ku ool ah oo loogu talagalay kala-soocidda qaybaha aan hydrocarbon ahayn ee paraffin. Waxay leedahay xulasho wanaagsan oo loogu talagalay milmida isophthalic acid iyo terephthalic acid: isophthalic acid waa mid ku milma DMF marka loo eego terephthalic acid, soo saarista dareeraha ama qayb ka mid ah Crystallization, labadaba waa la kala saari karaa. Warshadaha batroolka, DMF waxaa loo isticmaali karaa sidii nuugista gaaska si loo kala saaro loona sifeeyo gaasaska.
