[Ikhophi] I-N,N-Dimethylacetamide CAS: 127-19-5

incazelo emfushane:

I-N,N-Dimethylacetamide CAS: 127-19-5
Izakhiwo zamakhemikhali: Izakhiwo zamakhemikhali zifana kakhulu ne-N,N-dimethylformamide, futhi iyi-amide solvent emele. Uma ingekho i-asidi noma i-alkali, ngeke ibole uma ishiswa iye ekubileni ngaphansi kwengcindezi evamile, ngakho-ke ingacwiliswa ngaphansi kwengcindezi evamile. Izinga le-hydrolysis lihamba kancane kakhulu. Uma i-N,N-dimethylacetamide equkethe amanzi angu-5% ishiswa ku-95°C amahora angu-140, yi-0.02% kuphela eshiswayo. Kodwa-ke, lapho kukhona i-asidi ne-alkali, izinga le-hydrolysis liyakhuphuka. I-Saponification yenzeka lapho ishiswa lapho kukhona i-alkali enamandla.
isicelo
1. I-Pharmaceutical intermediate dimethylacetamide iyinto ebalulekile yokusetshenziswa kwemithi futhi isetshenziswa kabanzi ekukhiqizweni kwe-amoxicillin, i-cephalosporins kanye neminye imithi. Njenge-solvent noma i-cocatalyst, i-dimethylacetamide ingathuthukisa ikhwalithi yomkhiqizo kanye nesivuno uma kuqhathaniswa nezinyibilikisi zendabuko ze-organic. Ngo-2000, isidingo se-dimethylacetamide embonini yemithi sasicishe sibe ngu-6kt. Isidingo se-dimethylacetamide ngo-2006 sasicishe sibe ngu-9.6kt. 2. Ukukhiqizwa kwe-Acrylic fiber Ekukhiqizweni kwe-acrylic fiber, abanye basebenzisa indlela ye-dimethylacetamide. Njengamanje, ukukhiqizwa kwe-acrylic fiber yasekhaya I-Chemicalbook ifaka kakhulu i-sodium thiocyanate indlela yezinyathelo ezimbili, indlela ye-dimethylformamide yesinyathelo esisodwa kanye nendlela ye-dimethylacetamide yemvelo ngokwezinyibilikisi. Ngokombono wezinqubo nezimpawu zemishini, ukusetshenziswa kwezinto, umthelela wemvelo, ikhwalithi yomkhiqizo, Izici eziningi ezifana nokusebenza ngemuva kokucubungula, izinga lokwenziwa kwendawo kanye nemikhuba yentuthuko yangaphandle ziye zandisa imizamo yocwaningo lwesicelo kanye nokukhushulwa. I-Dimethylacetamide yasetshenziswa njengokuqhathanisa okuphelele. Kwasetshenziswa indlela ye-sodium thiocyanate enezinyathelo ezimbili kanye nendlela ye-dimethylacetamide organic wet. Intuthuko ethembisayo kakhulu. Njengamanje, ukufakwa okuningi kwe-acrylic fiber eShayina kusebenzisa izinqubo ezimanzi kusetshenziswa i-dimethylacetamide njengesinyibilikisi.

Izimakethe zethu eziyinhloko zifaka phakathi iMelika, iNdiya, i-Afrika, i-Indonesia, iTurkey, iNingizimu-mpumalanga ye-Asia, iNtshonalanga ye-Asia njalonjalo. Imikhiqizo emikhulu ye-MIT-IVY Industry ihlanganyela u-97% wemakethe yasekhaya egxile ekukhiqizeni nasekuphatheni, Singahlinzeka ngemikhiqizo ngezindleko ezincintisanayo. ngekhwalithi ephezulu kanye nentengo futhi siyakwamukela ukubonisana. Inkampani yethu inabantu abangochwepheshe abagxile ku-R&D yamakhemikhali kanye nokuphathwa okuzinzile, bahlinzeka ngemikhiqizo emihle yamakhemikhali enekhwalithi ephezulu kanye nensizakalo eseduze, futhi bahlinzeka ngemikhiqizo eyenzelwe wena ngokwezidingo zamakhasimende ethu. Sineqembu elisebenzayo lokuphatha elihle nelizikhuthazayo elinefilosofi efanayo, ukunakekela kanye nokuzibophezela ngokusebenzisana, ithimba lethu lilwela ukufeza impumelelo ekujabuliseni amakhasimende ethu kanye nathi. Siqhubeka nokuthuthukisa imikhiqizo yethu futhi sithuthukisa inethiwekhi yethu yesevisi, yokuthengisa. Ngakho-ke, siqala imodi yokuqala yokuthengisa ku-inthanethi eShayina, okuwukuhweba ngokuthengisa kwamaphakheji amancane okuletha izindlela zokuphatha ezahlukahlukene ngobuningi. Imikhiqizo yethu ithunyelwa kabanzi eNingizimu Korea, eVietnam, e-Australia, eYurophu naseNingizimu Melika, enconywe kakhulu ngamakhasimende ethu. Sigcizelela inkolelo yokuphatha ethi "Imakethe iyikhampasi yethu, Ikhwalithi iyimpilo yethu, Isikweletu siyimphefumulo wethu". Ukwethembana kwamakhasimende kuyisipho sethu sokuqala, ukwaneliseka kwabo kuyinjongo yethu enzima.

Isevisi Yamakhasimende Yomkhiqizo:
Inethiwekhi yethu yethimba le-akhawunti yamakhasimende e-JIT eShayina ithuthukisa futhi isebenzise imiqondo eyenzelwe wena ukuze amakhasimende ethu athole amakhemikhali ezimboni nawochwepheshe.
Izinzuzo zakho:
● Isevisi yamakhasimende ehlanganisiwe isekela ukwenza lula izinqubo zokuphatha, okuholela ekongeni isikhathi kanye nezindleko.
● Inethiwekhi yethu yaseShayina kanye nezixazululo zezokuthutha eziyinkimbinkimbi ziqinisekisa ukuthi amakhemikhali asezingeni elifanayo anikezwa amakhasimende anezindawo eziningana zokukhiqiza futhi anegalelo ekuphepheni ekuhleleni nasekuthembekeni kwezinqubo.
● Izinqubo zethu zithuthukiswa njalo futhi zivumelaniswa nezakhiwo nezidingo zamakhasimende ethu ezishintshashintshayo.

Ukuphakama kwensizakalo ye-Chemistry Logistics:
Insizakalo yokuthutha amakhemikhali iwubungcweti kakhulu futhi kufanele ibe ngcono ngaphansi kohlelo lwe-UN, ikakhulukazi ochungechungeni lwe-DGR Class. Sinikeza ikhambi lenhloso ekhethekile yokuthuthukisa insizakalo yokuthutha amakhemikhali kanye neqembu lokupakisha elifanele kanye nelebula lezinkampani zethu eziyinhloko. Amachweba ethu amakhulu aseShayina anezindawo zokugcina amakhemikhali ze-DGR ukusebenzisa amakhemikhali akhethekile nokusebenzisa wonke amaphepha ahlobene nawo.

Amakhono ethu okusabalalisa afaka:
● Ukulethwa okuguquguqukayo, izixazululo ezihlakaniphile
● Noma yini kusukela ekuthunyelweni okukhulu kwezinkulungwane zamathani kuye ekuthunyelweni okuncane kakhulu kwezimpahla ezipakishiwe ngisho namasampula.
● Ukugcinwa nokuthuthwa kwenqwaba yezimpushana noketshezi – ukuhanjiswa kwezimpahla emikhunjini – izimpushana noketshezi olukhulu
