I-N,N-Dimethylformamide CAS 68-12-2
I-Dimethylformamide iwuketshezi olungenambala nolusobala. Akuyona nje into eluhlaza yamakhemikhali esetshenziswa kabanzi, kodwa futhi iyisinyibilikisi esihle kakhulu esinokusetshenziswa okubanzi. I-Dimethylformamide iyinto eluhlaza ebalulekile yezemithi, i-petrochemical, isikhumba kanye neminye imboni.
I-Dimethylformamide ibizwa ngokuthi i-DMF. Iyinhlanganisela lapho iqembu le-hydroxyl le-formic acid lithathelwa indawo yiqembu le-dimethylamino, elinefomula yama-molecule i-HCON(CH3)2. Liwuketshezi olungenambala futhi olubonakalayo olunephunga elincane le-amine kanye nobuningi obuyi-0.9445 (25℃). Iphuzu lokuncibilika -61℃. Iphuzu lokubila 152.8℃. Iphuzu lokuflasha 57.78℃. Ubuningi bomhwamuko 2.51. Umfutho womhwamuko 0.49kpa (3.7mmHg25℃). Iphuzu lokusha liyi-445℃. Umkhawulo wokuqhuma kwengxube ye-steam nomoya yi-2.2~15.2%. Ukuchayeka emalangabini avulekile kanye nokushisa okuphezulu kungabangela ukusha nokuqhuma. Lingasabela ngamandla nge-sulfuric acid egxilile kanye ne-fuming nitric acid futhi liqhume ngisho nokuqhuma. Lixubene namanzi kanye neziningi zezinyibilikisi eziphilayo i-Chemicalbook. Liyisinyibilikisi esivamile sokusabela kwamakhemikhali. I-dimethylformamide emsulwa ayinaphunga, kodwa i-dimethylformamide yezinga lezimboni noma eyonakele inephunga elifana nelenhlanzi ngoba iqukethe ukungcola kwe-dimethylamine. Leli gama livela eqinisweni lokuthi iyi-dimethyl esikhundleni se-formamide (i-amide ye-formic acid), futhi womabili amaqembu e-methyl atholakala ku-athomu ye-N (nitrogen). I-Dimethylformamide iyi-solvent ye-polar (hydrophilic) aprotic enephuzu eliphezulu lokubila, elingakhuthaza indlela yokusabela ye-SN2. I-Dimethylformamide yenziwe nge-formic acid kanye ne-dimethylamine. I-Dimethylformamide ayizinzile (ikakhulukazi emazingeni okushisa aphezulu) lapho kukhona izisekelo eziqinile njenge-sodium hydroxide noma ama-acid aqinile njenge-hydrochloric acid noma i-sulfuric acid, futhi i-hydrolyzes ibe yi-formic acid kanye ne-dimethylamine.
Izinzile kakhulu emoyeni nalapho ishiswa ize ibile. Uma izinga lokushisa liphakeme kuno-350°C, ilahlekelwa amanzi futhi ikhiqize i-carbon monoxide kanye ne-dimethylamine. I-N,N-dimethylformamide iyi-solvent enhle kakhulu ye-aprotic polar engancibilikisa izinto eziningi eziphilayo nezingaphili futhi ixutshwa namanzi, ama-alcohols, ama-ether, ama-aldehydes, ama-ketone, ama-esters, ama-hydrocarbon a-halogenated kanye nama-hydrocarbon anuka kamnandi. . Ukuphela kwe-molecule ye-N,N-dimethylformamide okushajelwe kahle kuzungezwe amaqembu e-methyl, okwakha isithiyo se-space Chemicalbook esivimbela ama-ion angalungile ukuthi asondele futhi sihlobanise ama-ion amahle kuphela. Ama-anion angenalutho asebenza kakhulu kunama-anion axazululiwe. Ukusabela okuningi kwe-ionic kulula ukukwenza ku-N,N-dimethylformamide kunakuma-solvent ajwayelekile e-protic. Isibonelo, ama-carboxylates nama-hydrocarbon a-halogenated asabela ku-N,N-dimethylformamide ekushiseni kwegumbi. , angakhiqiza ama-esters anezivuno eziphezulu, futhi afaneleka kakhulu ekuhlanganisweni kwama-esters avinjelwe yi-sterically.
