    N-dimethylformamide

    Tshuaj Tshuaj Muaj Zog

    N, n-dimethylformamide yog cov kua tsis muaj kob lossis kua ntshav dub ntawm 153 ° C thiab lub vapor siab ntawm 380 PA ntawm 20 ° C. Nws yog dawb soluble hauv dej thiab soluble hauv cawv, acetone thiab benzene. N, n-n-dimethylformamide yog siv raws li cov kuab tshuaj, catalalt thiab roj nqus. Res kom tsaus muag nrog cov sulfuric acid, fuming nitric acid thiab tuaj yeem tawg. Ntshiab ntshiab dimethylformamide yog tsis muaj ntxhiab, tab sis kev muaj kev lag luam dimetylformamide muaj tus ntses tsis hnov ​​tsw vim tias nws muaj impurities ntawm dimethylamine. Dimethylformamide yog tsis ruaj khov (tshwj xeeb yog nyob rau hauv lub xub ntiag ntawm hydium hydrocide lossis sulfuric acid los yog hydfuric acid los yog hydrolyzed rau formic acid thiab dimethylamine.

    N, n-dmf) yog cov kua ntshiab uas tau siv dav hauv kev lag luam vim yog qhov ua kom muaj zog ntxiv nrog dej thiab feem ntau cov emolic.

    Dimethylformamide yog feem ntau siv los ua kev muaj kuab tshuaj. Dimethylformamide cov kev daws teeb meem yog siv Kev Siv Kev Haus Luam Ntawv Polymer, cov yeeb yaj kiab, thiab txheej ci deg; kom tau yooj yim spinning ntawm acrylic fibers; Txhawm rau tsim cov khoom siv hlau, thiab raws li kev lag luam crystallization hauv kev lag luam kws tshuaj.

    DMF kuj tseem siv tau rau cov qauv nrog cov alkylrithium lossis grigard reagents.

    Nws yog siv los ua tus reagent hauv bouseult aldehyde synthesis thiab tseem nyob hauv vilsmeier-hack tshuaj tiv thaiv. Nws ua raws li kev catalyst nyob rau hauv synthesis ntawm acyl chlorides. Nws yog siv rau kev sib cais thiab ua kom rov qab muaj roj los ntawm ank. DMF nrog methylene chloride kev ua raws li kev tshem tawm ntawm varnish lossis lacquers. Nws kuj yog siv rau hauv kev tsim cov nplaum, cov fibers thiab cov yeeb yaj kiab.

    N, n-dmf) nyob rau (DMF) yog qhov hnyav nrog kev npaj evaporation nrog ntau yam ntawm hydrophobic organic sib sau siv hauv molecular biology biology.

    N, n-dimethylformamide tau siv rau solubilize mtt muaju hauv cell kev ua haujlwm ntawm cov pwm nthuav dav ntawm cov enzyme siab.

    Kev noj ntau thoob ntiaj teb ntawm DMF xyoo 2001 tau kwv yees li 285, 000 metric tonnes thiab feem ntau ntawm cov uas tau siv los ua cov kuab tshuaj muaj zog.

    Yuav Yuav Yuav Li Cas Los Ntawm Peb

    Chemwin tuaj yeem muab ntau qhov ntau ntawm hydrocarbons thiab cov kuab tshuaj lom neeg rau cov neeg siv khoom lag luam.Ua ntej ntawd, thov nyeem cov ntaub ntawv hauv qab no hais txog kev ua lag luam nrog peb: 

    1. Kev ruaj ntseg

    Kev nyab xeeb yog peb qhov tseem ceeb tshaj plaws. Ntxiv rau muab cov neeg siv khoom nrog kev siv cov ntaub ntawv hais txog peb cov khoom lag luam, peb kuj tau cog lus tias kev muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov neeg ua haujlwm raug txo qis thiab ua tau tsawg kawg nkaus. Yog li ntawd, peb xav kom tus qhua tuaj noj mov kom ntseeg tau tias qhov tsim nyog tso tseg thiab kev nyab xeeb cov qauv kev nyab xeeb tau ntsib cov ntawv tshaj tawm HSSE (thov saib cov nqe lus dav dav thiab cov ntsiab lus ntawm kev muag khoom hauv qab). Peb cov kws paub HDSE tau muab cov kev taw qhia rau cov qauv no.

    2. Kev Xa Tawm

    Cov neeg siv khoom tuaj yeem xaj thiab xa cov khoom lag luam los ntawm Chemwin, lossis lawv tuaj yeem tau txais cov khoom los ntawm peb cov khoom lag luam tsim khoom. Cov qauv muaj kev thauj khoom muaj cov tsheb thauj neeg muaj tsheb thauj khoom, tsheb ciav hlau lossis cov neeg thauj khoom ntau (cais cov mob siv).

    Nyob rau hauv cov ntaub ntawv uas cov neeg yuav tsum tau ua, peb tuaj yeem hais cov cai ntawm cov nkoj lossis cov qauv kev nyab xeeb thiab siv cov qauv kev nyab xeeb tshwj xeeb / tshuaj xyuas thiab cov tseev kom ua.

    3. Yam tsawg kawg txiav txim kom muaj nuj nqis

    Yog tias koj yuav khoom los ntawm peb lub vev xaib, qhov kev txiav txim yam tsawg kawg nkaus yog 30 tons.

    4. Upayment

    Txoj kev them nqi them yog ncaj qha txiav tawm tsis pub dhau 30 hnub los ntawm daim ntawv qhia nqe.

    5. Xa cov ntaub ntawv

    Cov ntaub ntawv hauv qab no tau muab rau txhua qhov kev xa khoom:

    Bill Nqi ntawm Lading, Cmr Waybill lossis lwm daim ntawv thauj khoom uas muaj feem xyuam

    Daim ntawv pov thawj ntawm kev ntsuas lossis kev ua raws (yog tias yuav tsum tau)

    · HSSEs cov ntaub ntawv ntsig txog kab nrog cov kev cai
