Hoʻohana Huahana
Hoʻokumu ʻia ka Acrylonitrile e ka propylene ammoxidation, kahi e hoʻopili ʻia ai ka propylene, ammonia, a me ka ea e ka catalyst i kahi moena wai.Hoʻohana nui ʻia ka Acrylonitrile ma ke ʻano he co-monomer i ka hana ʻana i nā fibers acrylic a me modacrylic.Hoʻohana ʻia ka hana ʻana o nā plastics, nā uhi ʻili, nā elastomers nitrile, nā pale pale, a me nā mea hoʻopili.ʻO ia hoʻi kahi mea waena kemika i ka synthesis o nā antioxidants like ʻole, nā lāʻau lapaʻau, nā mea ʻulaʻula, a me ka surface-active.
1. ʻO Acrylonitrile i hana ʻia me ka polyacrylonitrile fiber, ʻo ia hoʻi ka fiber acrylic.
2. Hiki ke copolymerized ka Acrylonitrile a me ka butadiene e hana i ka nitrile rubber.
3. Acrylonitrile, butadiene, styrene copolymerized e hoʻomākaukau i ka resin ABS.
4. Hiki i ka Acrylonitrile hydrolysis ke hana i ka acrylamide, ka waikawa acrylic a me kāna esters.
Loaʻa ka hapa nui o ka fiber carbon o ka honua mai ka PAN i hana ʻia me ka monomer ACN o propylene a me ka amonia.Hoʻopili ʻia ʻo ACN i PAN ma o ka hoʻohui ʻana me nā comonomers acrylic plasticized a me kahi catalyst.ʻO kēia hana kemika holoʻokoʻa a me ka hoʻololi ʻana he paʻakikī, pipiʻi a me ka ikaika.Eia hou, no ka hana ʻana i 1 kilokani kalapona e pono ai i 2 kilokani o PAN, e hāʻawi ana i ka PAN i ka helu hoʻololi ʻana o 50% wale nō - a me kahi kapuaʻi kinoea nui.
