tsananguro pfupi:

N,N-DIMETHYLFORMAMIDE inopfupikiswa seDMF. Imusanganiswa unobva pakutsiviwa kweboka rehydroxyl reformic acid neboka redimethylamino, uye fomura yemamorekuru iHCON(CH3)2. Imvura isina ruvara, yakajeka, inofashaira zvakanyanya ine hwema hweamine hushoma uye huwandu hwe 0.9445 (25°C). Nzvimbo yekunyunguduka -61 ℃. Nzvimbo yekufashaira 152.8 ℃. Nzvimbo yekupenya 57.78 ℃. Huwandu hwemhepo 2.51. Kumanikidzwa kwemhepo 0.49kpa (3.7mmHg25 ℃). Nzvimbo yekuzvibatisa otomatiki i445°C. Muganho wekuputika kwemhepo nemhepo musanganiswa i2.2 kusvika 15.2%. Kana paine moto wakavhurika uye kupisa kwakanyanya, inogona kukonzera kupisa nekuputika. Inogona kuita zvine simba nesulfuric acid yakakora uye nitric acid inofuridza uye inotoputika. Inosanganiswa nemvura uye organic solvents dzakawanda. Iyo inonyungudutsa inowanzo shandiswa pakuita kwemakemikari. N,N-DIMETHYLFORMAMIDE yakachena haina hwema, asi N,N-DIMETHYLFORMAMIDE yemhando yepamusoro kana kuti yakaora ine hwema hwakaita sehwehove nekuti ine tsvina yedimethylamine.

Zita iri rinobva pakuti ndiro dimethyl inotsiva formamide (amide ye formic acid), uye mapoka ese ari maviri e methyl ari paatomu yeN (nitrogen). N,N-DIMETHYLFORMAMID isolvent inofashaira zvakanyanya (hydrophilic) polar (hydrophilic) aprotic, uye Chemicalbook inogona kukurudzira SN2 reaction mechanism. N,N-DIMETHYLFORMAMID inogadzirwa uchishandisa formic acid ne dimethylamine. N,N-DIMETHYLFORMAMID haina kugadzikana (kunyanya pakupisa kwakanyanya) kana paine mabhesi akasimba akadai se sodium hydroxide kana ma strong acid akadai se hydrochloric acid kana sulfuric acid, uye inochinja kuita formic acid ne dimethylamine. Inogadzikana zvikuru mumhepo uye kana yapiswa kusvika yafashaira. Kana tembiricha yakakwira kupfuura 350 ℃, inorasikirwa nemvura uye inoburitsa carbon monoxide ne dimethylamine. N,N-DIMETHYLFORMAMID chinhu chakanaka che aprotic polar solvent, chinogona kunyungudutsa zvinhu zvakawanda zve organic ne inorganic, uye chinogona kusanganiswa nemvura, alcohols, ethers, aldehydes, ketones, esters, halogenated hydrocarbons uye aromatic hydrocarbons, nezvimwewo. Mugumo we positively charged we N,N-DIMETHYLFORMAMID molecule wakakomberedzwa ne methyl groups, zvichiita steric prohibition, zvekuti negative ions haigoni kusvika, asi positive ions chete ndiyo inobatanidzwa. Naked anion inoshanda zvakanyanya kupfuura solvated anion. Mazhinji maionic reactions anoitwa zviri nyore mu N,N-DIMETHYLFORMAMID kupfuura mune general protic solvents, semuenzaniso, reaction yema carboxylates nema halogenated hydrocarbons mu N,N-DIMETHYLFORMAMID patembiricha yemumba, inogona kugadzira ma high-goal esters, akakodzera kugadzirwa kwema sterically hindered esters.

Mashandisirwo eDMF

DMF chinhu chakanaka chekugadzirisa mapolymer akasiyana-siyana akadai se polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, nezvimwewo, uye chinogona kushandiswa pakunyorova mafiber ekugadzira akadai se polyacrylonitrile fibers, uye kugadzira polyurethane; Inoshandiswa kugadzira purasitiki; inogona zvakare kushandiswa semuchina wekubvisa pendi; inogona zvakare kunyungudutsa mamwe mapigment asinganyungudike zvakanyanya, kuitira kuti mapigment acho ave nehunhu hwemadhayi. DMF inoshandiswa pakuburitsa nekuparadzanisa butadiene kubva kuzvikamu zveC4 uye isoprene kubva kuzvikamu zveC5, uye inogona zvakare kushandiswa se reagent inoshanda yekuparadzanisa zvikamu zvisiri zvehydrocarbon kubva kuparafini. Ine sarudzo yakanaka yekunyunguduka kweisophthalic acid neterephthalic acid: isophthalic acid inonyunguduka zvakanyanya muDMF kupfuura terephthalic acid, kubvisa solvent kana partial Crystallization, zviviri izvi zvinogona kuparadzaniswa. Muindasitiri yepetrochemical, DMF inogona kushandiswa semuchina wekubvisa gasi kuti iparadzanise uye ichenese magasi. Semushonga wekuchenesa weChemicalbook muindasitiri yepolyurethane, inonyanya kushandiswa mukugadzira dehwe rakanyorova rekugadzira; semushonga wekugadzira fiber yeacrylic, inonyanya kushandiswa mukugadzira fiber yeacrylic inopetwa nedry spinning; muindasitiri yemagetsi sekudzimisa zvikamu zvetin-plated uye mabhodhi edunhu. Mamwe maindasitiri anosanganisira vatakuri vemagasi ane njodzi, zvinonyungudutsa zvekugadzira mishonga, zvinonamira, nezvimwewo. Mukuita kweorganic, DMF haingoshandiswi zvakanyanya semushonga wekuita, asiwo chinhu chakakosha mukugadzirwa kweorganic.
