N, N-Dimethylformamide CAS 68-12-2
Dimethylformamide yog ib yam kua tsis muaj xim thiab pob tshab. Nws tsis yog tsuas yog siv dav hauv cov tshuaj lom neeg xwb, tab sis kuj yog ib qho tshuaj yaj zoo heev uas siv tau ntau yam. Dimethylformamide yog ib yam khoom siv tseem ceeb rau kev lag luam tshuaj, petrochemical, tawv thiab lwm yam lag luam.
Dimethylformamide hu ua DMF. Nws yog ib qho tshuaj uas pawg hydroxyl ntawm formic acid hloov los ntawm pawg dimethylamino, nrog rau cov mis molecular HCON (CH3) 2. Nws yog ib qho kua tsis muaj xim thiab pob tshab uas muaj ntxhiab amine me me thiab qhov ceev ntawm 0.9445 (25 ℃). Melting point -61 ℃. Boiling point 152.8 ℃. Flash point 57.78 ℃. Vapor density 2.51. Vapor pressure 0.49kpa (3.7mmHg 25 ℃). Autoignition point yog 445 ℃. Qhov txwv ntawm kev tawg ntawm cov pa thiab cua sib xyaw yog 2.2 ~ 15.2%. Kev raug rau cov nplaim taws qhib thiab kub siab yuav ua rau muaj kev kub hnyiab thiab tawg. Nws tuaj yeem ua rau muaj kev kub ntxhov nrog cov kua qaub sulfuric thiab cov kua qaub nitric fuming thiab txawm tias tawg. Nws sib xyaw nrog dej thiab feem ntau cov kuab tshuaj organic. Nws yog ib qho kuab tshuaj rau cov tshuaj tiv thaiv tshuaj. Dimethylformamide ntshiab tsis muaj ntxhiab, tab sis qib kev lag luam lossis dimethylformamide uas lwj lawm muaj ntxhiab ntses vim nws muaj cov khoom tsis huv dimethylamine. Lub npe los ntawm qhov tseeb tias nws yog dimethyl hloov formamide (amide ntawm formic acid), thiab ob pawg methyl nyob ntawm N (nitrogen) atom. Dimethylformamide yog cov kuab tshuaj polar (hydrophilic) aprotic nrog lub ntsiab lus kub siab, uas tuaj yeem txhawb nqa SN2 cov tshuaj tiv thaiv. Dimethylformamide yog ua los ntawm formic acid thiab dimethylamine. Dimethylformamide tsis ruaj khov (tshwj xeeb tshaj yog thaum kub siab) nyob rau hauv qhov muaj cov hauv paus muaj zog xws li sodium hydroxide lossis cov kua qaub muaj zog xws li hydrochloric acid lossis sulfuric acid, thiab hydrolyzes rau formic acid thiab dimethylamine.
Nws ruaj khov heev hauv huab cua thiab thaum cua sov kom npau. Thaum qhov kub siab tshaj 350 ° C, nws poob dej thiab tsim cov pa roj carbon monoxide thiab dimethylamine. N, N-dimethylformamide yog cov tshuaj aprotic polar zoo heev uas tuaj yeem yaj feem ntau cov organic thiab inorganic thiab sib xyaw nrog dej, cawv, ethers, aldehydes, ketones, esters, halogenated hydrocarbons thiab aromatic hydrocarbons. . Qhov kawg ntawm N, N-dimethylformamide molecule yog ib puag ncig los ntawm methyl pawg, tsim ib qho chaw thaiv uas tiv thaiv cov ions tsis zoo los ntawm kev los ze thiab tsuas yog koom nrog cov ions zoo. Cov anions liab qab muaj zog ntau dua li cov anions solvated. Ntau cov tshuaj tiv thaiv ionic yooj yim dua los ua hauv N, N-dimethylformamide dua li cov tshuaj tiv thaiv protic dav dav. Piv txwv li, carboxylates thiab halogenated hydrocarbons react hauv N, N-dimethylformamide ntawm chav tsev kub. , tuaj yeem tsim cov esters nrog cov txiaj ntsig siab, thiab tshwj xeeb tshaj yog tsim rau kev tsim cov esters hindered sterically.
