Acetonitrile yog cov tshuaj sib xyaw nrog cov mis CH 3 CN . Cov kua tsis muaj xim no yog cov organic yooj yim tshaj plaws nitrile . Nws yog tsim los ua ib tug byproduct ntawm acrylonitrile tshuaj tsim khoom. Nws yog siv los ua ib qho polar aprotic hnyav hauv cov organic synthesis thiab hauv kev ua kom huv ntawm butadiene.
Xav txog qhov no, vim li cas acetonitrile siv los ua cov kuab tshuaj?
Cov B kuab tshuaj feem ntau yog HPLC qib organic kuab tshuaj xws li Cov tshuaj acetonitrile los yog methanol nrog 0.1% acid. Cov kua qaub yog siv txhawm rau txhim kho cov chromatographic ncov puab thiab muab ib qhov chaw ntawm protons nyob rau theem rov qab LC / MS. Hauv peb txoj haujlwm peb siv acetonitrile tshuaj raws li peb cov organic kuab tshuaj.
Tsis tas li ntawd, puas yog acetonitrile tib yam li acetone? Qhov sib txawv tseem ceeb ntawm Cov tshuaj acetonitrile thiab acetone yog tias Cov tshuaj acetonitrile yog nitrile compound, hos acetone yog ketone. Cov tshuaj acetonitrile yog ib qho organic compound uas muaj cov tshuaj formula CH3CN thaum Acetone yog ib qho organic compound uas muaj cov tshuaj formula (CH3)2CO.
Raws li txoj cai, yog acetonitrile yog cov kuab tshuaj polar?
Cov tshuaj acetonitrile muaj 5.8 polarity qhov ntsuas. Dej yog a kuab tshuaj Tsuas yog lwm tus polar tshuaj. Hydrocarbons tsis yog polar yog li ntawd lawv yog cov kuab tshuaj Tsuas yog rau lwm yam uas tsis yog- polar tshuaj. Tsis zoo li hydrocarbons, Ethyl Cawv muaj ob qho tib si polar thiab tsis- polar chemical pawg ntawm cov molecule.
Puas yog acetonitrile soluble hauv dej?
Cov tshuaj acetonitrile yog miscible kiag li nrog dej , thiab nws lub siab dielectric tas li thiab dipole lub sij hawm (Table 2.1) ua rau nws ib tug haum hnyav rau ntau inorganic thiab organic tebchaw. Feem ntau cov polar organic cov ntaub ntawv yog soluble hauv Cov tshuaj acetonitrile.

Dab tsi yog cov kuab tshuaj txuas txuas?
Hnyav-weld sib koom. hnyav-weld sib koom. Cov yeeb nkab sib koom ua los ntawm kev nthuav cov cement rau ntawm ob lub yas yas kom koom nrog. Cov cement ua tshuaj lom nrog cov chaw no, yog li ua kom cov khoom tawg
Dab tsi yog cov tshuaj tiv thaiv ntawm daim ntawv xiav litmus thaum dipped rau hauv cov kua qaub uas muaj tshuaj?
Daim ntawv liab litmus reacts rau alkaline tshuaj los ntawm tig xiav, thaum xiav litmus ntawv reacts rau acidic tshuaj los ntawm tig liab
Cov kuab tshuaj raws li cov tshuaj ntxuav yog dab tsi?
Solvent Cleaners Solvent-based cleaners tseem nrov hauv cov ntawv thov kev lag luam vim lawv lub zog ntxuav; lawv tshem tawm cov tuab, ci rau cov roj, av, ntim, cov kua dej, thiab cov roj. Qee qhov piv txwv ntawm kev ntxuav cov kuab tshuaj muaj zog yog acetone, methyl ethyl ketone, toluene, nPB, thiab trichlorethylene (TCE)
Dab tsi ntawm cov kuab tshuaj yog roj av ether polar lossis nonpolar)? Piav?
Cov roj av ether yog sib xyaw ntawm ntau cov hydrocarbons, feem ntau yog pentane thiab hexane, uas nyob rau hauv lem tsuas yog tsim los ntawm Carbon thiab Hydrogen, (uas tam sim no qhov tseem ceeb ntawm ze electronegativity), yuav luag tsis muaj polar
Cov kuab tshuaj raws li cov tshuaj yog dab tsi?
Lo lus 'hloov' yog siv rau ntau cov tshuaj lom neeg uas siv los yaj lossis dilute lwm yam khoom lossis cov khoom siv. Lawv feem ntau yog cov kua organic. Ntau cov kuab tshuaj kuj tseem siv los ua cov tshuaj intermediates, fuels, thiab ua cov khoom ntawm ntau yam khoom
