    Qaab molecular:C3H7NO

    CAS Maya:68-12-2

    Qaab dhismeedka molecular ee alaabta:

    N-Dimethylformamide

    HANTIDA Kiimikada

    N,N-Dimethylformamide waa dareere aan midab lahayn ama wax yar oo huruud ah oo leh barta karkarinta 153°C iyo cadaadiska uumiga 380 Pa at 20°C.Waxay si xor ah ugu milmi kartaa biyaha waxayna ku milmaysaa aalkolada, acetone iyo benzene.N, N-Dimethylformamide waxaa loo isticmaalaa sida dareere, kicinta iyo nuuga gaaska.Si xoog leh uga fal celi sulfuric acid, qiiqa nitric acid oo xitaa way qarxi kartaa.Dimethylformamide saafi ah waa mid aan ur lahayn, laakiin darajada warshadaha ama wax laga beddelay Dimethylformamide waxay leedahay ur kalluun sababtoo ah waxa ku jira wasakhda Dimethylamine.Dimethylformamide waa mid aan degganayn (gaar ahaan heerkulka sare) iyadoo ay jirto saldhig xooggan sida sodium hydroxide ama asiidh xooggan sida hydrochloric acid ama sulfuric acid, waxaana lagu shubaa formic acid iyo dimethylamine.

    N, N-Dimethylformamide (DMF) waa dareere cad oo si weyn loogu isticmaalo warshadaha sida dareere, wax lagu daro, ama dhexdhexaad ah sababtoo ah khalkhal ballaadhan oo biyo ah iyo dareerayaasha dabiiciga ah ee caadiga ah.

    Dimethylformamide waxaa marka hore loo isticmaalaa sida dareere warshadeed.Xalalka Dimethylformamide waxaa loo isticmaalaa fiilooyinka polymer-ka, filimada, iyo dahaarka dusha sare;si loo oggolaado in si sahlan loo miiqiyo fiilooyinka akril;si ay u soo saaraan dhaldhalaalka silig, iyo sida dhexdhexaad ah crystallization warshadaha daawooyinka.

    DMF waxa kale oo loo isticmaali karaa samaynta alkyllithium ama reagents Grignard.

    Waxa loo isticmaalaa sidii reagent ahaan isku-dhafka Bouveault aldehyde iyo sidoo kale falcelinta Vilsmeier-Haack.Waxay u shaqeysaa sidii kicinta isku-dhafka acyl chlorides.Waxa loo isticmaalaa in lagu kala saaro laguna sifeeyo cayriin gaaska olefin.DMF oo ay weheliso chloride methylene waxay u shaqeysaa sidii ka saarista varnish ama lacquers.Waxa kale oo loo isticmaalaa samaynta xabagta, fiilooyinka iyo filimada.

    N, N-Dimethylformamide (DMF) waa dareere leh heerka uumiga hooseeya, faa'iido u leh diyaarinta xalalka kala duwan ee xeryahooda organic hydrophobic loo isticmaalo codsiyada bayoloji molecular.

    N,N-Dimethylformamide waxaa loo isticmaalay in lagu milmo MTT crystals ee qiyaasaha suurtagalka ah ee unugyada.Waxa kale oo loo isticmaalay baaritaanka firfircoonida feruloyl esterase ee caaryada muujinaya firfircoonida sare ee enzyme.

    Isticmaalka adduunka oo dhan ee DMF sanadkii 2001 wuxuu ahaa ku dhawaad ​​285, 000 metric tonnes waxaana intiisa badan loo isticmaalay dareere warshadeed.

    SIDEE NOOGA IIBSAN KARAA

    Chemwin waxay siin kartaa noocyo badan oo kaarboon-karboon ah iyo dareerayaasha kiimikaad ee macaamiisha warshadaha.Intaa ka hor, fadlan akhri macluumaadka aasaasiga ah ee soo socda ee ku saabsan ganacsiga nala samee: 

    1. Amniga

    Badbaadadu waa mudnaantayada koowaad.Marka laga soo tago siinta macaamiisha macluumaadka ku saabsan isticmaalka badbaadada iyo deegaanka saaxiibtinimo leh ee alaabtayada, waxaan sidoo kale go'aansanay inaan hubinno in khataraha badbaadada shaqaalaha iyo qandaraaslayaasha la dhimay ilaa ugu yaraan macquul ah oo macquul ah.Sidaa darteed, waxaan uga baahannahay macmiilka inuu hubiyo in heerarka badbaadada dejinta iyo kaydinta ku habboon ay buuxiyeen ka hor inta aan la keenin (fadlan tixraac lifaaqa HSSE ee shuruudaha iyo shuruudaha iibka ee hoose).Khubaradayada HSSE waxay ku siin karaan hagitaan heerarkan.

    2. Habka gaarsiinta

    Macaamiisha waxay ka dalban karaan oo ka keeni karaan alaabta chemwin, ama waxay ka heli karaan alaabta warshadeena wax soo saarka.Noocyada gaadiidka ee la heli karo waxaa ka mid ah baabuurta xamuulka qaada, tareenada ama gaadiidka casriga ah (xaalad gooni ah ayaa jira).

    Marka laga hadlayo shuruudaha macmiilka, waxaan qeexi karnaa shuruudaha maraakiibta ama booyadaha waxaanan adeegsan karnaa heerarka badbaadada / dib u eegista iyo shuruudaha.

    3. Tirada dalabka ugu yar

    Haddii aad alaab ka soo iibsato mareegahayaga, tirada dalbashada ugu yar waa 30 tan.

    4.Bixinta

    Habka lacag bixinta caadiga ah ayaa si toos ah looga jarayaa 30 maalmood gudahooda laga bilaabo qaansheegta.

    5. Dukumentiga keenista

    Dukumeentiyada soo socda ayaa la keenay keenista kasta:

    Bill of Lading, CMR Waybill ama dukumeenti gaadiid oo kale oo khuseeya

    Shahaadada Falanqaynta ama waafaqsanaanta (haddii loo baahdo)

    Dukumeenti la xidhiidha HSSE oo waafaqsan xeerarka

    Dukumeenti kastamka oo waafaqsan xeerarka (haddii loo baahdo)
