Huahana molecular structure:
N,N-Dimethylformamide he wai waihoʻoluʻu ʻole a melemele iki paha me kahi paila o 153°C a me kahi kaomi mahu o 380 Pa ma 20°C. Hiki ke hoʻoheheʻe ʻia i ka wai a hiki ke hoʻoheheʻe ʻia i loko o nā ʻona, acetone a me benzene. Hoʻohana ʻia ʻo N, N-Dimethylformamide e like me ka solvent, catalyst a me ke kinoea absorbent. E hana ikaika me ka sulfuric acid concentrated, fuming nitric acid a hiki ke pahū. ʻAʻohe ʻala ʻo Dimethylformamide maʻemaʻe, akā ʻo ka ʻenehana a i ʻole ka Dimethylformamide i hoʻololi ʻia he ʻala iʻa no ka mea aia nā haumia o Dimethylamine. ʻAʻole paʻa ka Dimethylformamide (ʻoi loa i nā wela kiʻekiʻe) i mua o kahi kumu ikaika e like me ka sodium hydroxide a i ʻole ka waikawa ikaika e like me ka waika hydrochloric a i ʻole ka sulfuric acid, a ua hydrolyzed i ka formic acid a me ka dimethylamine.
ʻO N,N-Dimethylformamide (DMF) kahi wai maʻemaʻe i hoʻohana nui ʻia i nā ʻoihana e like me ka solvent, additive, a i ʻole ka mea waena ma muli o kona hiki ʻole i ka wai a me nā mea hoʻoheheʻe kūlohelohe maʻamau.
Hoʻohana nui ʻia ʻo Dimethylformamide ma ke ʻano he mea hoʻoheheʻe ʻoihana. Hoʻohana ʻia nā hoʻonā Dimethylformamide no ka hoʻoponopono ʻana i nā fibers polymer, nā kiʻiʻoniʻoni, a me nā uhi ʻili; e ʻae i ka wili maʻalahi o nā fiber acrylic; e hana i nā enamels uea, a ma ke ʻano he crystallization medium ma ka ʻoihana lāʻau lapaʻau.
Hiki ke hoʻohana ʻia ʻo DMF no ka formylation me ka alkyllithium a i ʻole Grignard reagents.
Hoʻohana ʻia ia ma ke ʻano he reagent ma Bouveault aldehyde synthesis a me ka pane ʻana o Vilsmeier-Haack. Hana ia ma ke ʻano he catalyst i ka synthesis o acyl chlorides. Hoʻohana ʻia ia no ka hoʻokaʻawale ʻana a me ka hoʻomaʻemaʻe ʻana i ke kino mai ke kinoea olefin. ʻO DMF me ka methylene chloride ka mea e wehe ai i ka varnish a i ʻole nā lacquers. Hoʻohana ʻia ia i ka hana ʻana i nā adhesives, fibers a me nā kiʻiʻoniʻoni.
ʻO N,N-Dimethylformamide (DMF) he mea hoʻoheheʻe me ka haʻahaʻa haʻahaʻa haʻahaʻa, pono no ka hoʻomākaukau ʻana i nā hāʻina me nā ʻano mea like ʻole hydrophobic i hoʻohana ʻia i nā noi biology molecular.
Ua hoʻohana ʻia ʻo N, N-Dimethylformamide e hoʻoheheʻe i nā kristal MTT i ka hoʻāʻo ʻana o ka cell viability assays.
ʻO ka hoʻohana ʻana i ka honua holoʻokoʻa o DMF i ka makahiki 2001 ma kahi o 285,000 metric tonnes a ʻo ka hapa nui o ia mea i hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe ʻenehana.
Hiki iā Chemwin ke hāʻawi i ka nui o nā hydrocarbons nui a me nā mea hoʻoheheʻe kemika no nā mea kūʻai aku ʻoihana.Ma mua o kēlā, e heluhelu i ka ʻike kumu e pili ana i ka hana ʻana me mākou:
1. Palekana
ʻO ka palekana kā mākou mea nui. Ma waho aʻe o ka hāʻawi ʻana i nā mea kūʻai aku i ka ʻike e pili ana i ka hoʻohana palekana a me ka hoʻohana ʻana i ka nohona o kā mākou huahana, ua paʻa pū mākou i ka hōʻoia ʻana e hōʻemi ʻia nā pilikia palekana o nā limahana a me nā mea hana ʻaelike i kahi liʻiliʻi kūpono a hiki. No laila, koi mākou i ka mea kūʻai aku e hōʻoia i ka hoʻokō ʻana i nā kūlana palekana kūpono no ka wehe ʻana a me ka mālama ʻana ma mua o kā mākou hoʻouna ʻana (e ʻoluʻolu e nānā i ka appendix HSSE ma nā ʻōlelo a me nā kūlana kūʻai ma lalo). Hiki i kā mākou mau loea HSSE ke hāʻawi i ke alakaʻi i kēia mau kūlana.
2. Keʻano hoʻouna
Hiki i nā mea kūʻai ke kauoha a hāʻawi i nā huahana mai chemwin, a i ʻole hiki iā lākou ke loaʻa nā huahana mai kā mākou hale hana. ʻO nā ʻano kaʻa kaʻa i loaʻa ke kaʻa kaʻa, kaʻaahi a i ʻole ka halihali multimodal (e pili ana nā kūlana kaʻawale).
I ka hihia o nā koi o ka mea kūʻai aku, hiki iā mākou ke kuhikuhi i nā koi o nā moku a i ʻole nā pahu pahu a kau i nā kūlana palekana / loiloi kūikawā a me nā koi.
3. Ka nui kauoha liʻiliʻi
Inā kūʻai ʻoe i nā huahana mai kā mākou pūnaewele, ʻo ka liʻiliʻi liʻiliʻi he 30 tons.
4. Uku
ʻO ke ala uku maʻamau ka unuhi pololei ʻana i loko o 30 mau lā mai ka invoice.
5. Nā palapala hoʻouna
Hāʻawi ʻia kēia mau palapala i kēlā me kēia hoʻouna:
· Bill of Lading, CMR Waybill a i ʻole nā palapala halihali e pili ana
· Palapala hōʻoia o ka nānā ʻana a i ʻole Conformity (inā koi ʻia)
· Nā palapala pili i ka HSSE e like me nā lula
· Nā palapala dute e like me nā lula (inā pono)
