Ethylene (C2H4)

Zosintha zaukadaulo

Nthawi zonse, ethylene ndi gasi wopanda mtundu, wonunkhiza pang'ono woyaka ndi kachulukidwe ka 1.178g/L, womwe ndi wocheperako pang'ono kuposa mpweya. Simasungunuka m'madzi, sasungunuka mu ethanol, komanso sungunuka pang'ono mu ethanol, ketones, ndi benzene. , Kusungunuka mu etha, mosavuta sungunuka mu zosungunulira organic monga carbon tetrachloride.Ethylenendi amodzi mwa mankhwala omwe ali ndi zotulutsa zazikulu kwambiri padziko lonse lapansi. Makampani a ethylene ndiye maziko amakampani a petrochemical.EthyleneZogulitsa zimakhala ndi zinthu zopitilira 75% zamafuta a petrochemical ndipo zimakhala ndi gawo lofunikira pazachuma cha dziko. Dziko lapansi lawona kupanga kwa ethylene ngati chimodzi mwazinthu zofunikira pakuyezera kukula kwamakampani amafuta amafuta mdziko muno. Ethylene ndi yofunika organic mankhwala zofunika zopangira, makamaka ntchito kupanga polyethylene, ethylene propylene mphira, polyvinyl kolorayidi, etc. Ethylene ndi chimodzi mwa zinthu zofunika kwambiri zopangira petrochemical makampani. Pankhani ya zida zopangira, zimagwiritsidwa ntchito kwambiri popanga polyethylene, vinyl chloride, etc.; ponena za kaphatikizidwe ka organic, amagwiritsidwa ntchito kwambiri popanga ethanol, ethylene oxide, ethylene glycol, acetaldehyde, ndi propylene. Mitundu yosiyanasiyana ya zinthu zoyambira organic synthesis monga aldehydes ndi zotumphukira zake; kudzera mu halogenation, imatha kupanga chlorethylene, chloroethane, bromoethane, etc. Ethylene imagwiritsidwanso ntchito makamaka ngati mpweya wokhazikika pazida zowunikira mumakampani a petrochemical; amagwiritsidwa ntchito ngati mpweya wokometsera bwino wa zipatso monga malalanje, malalanje, nthochi, etc.; amagwiritsidwa ntchito popanga mankhwala ndi zipangizo zamakono; amagwiritsidwa ntchito popanga galasi lapadera lamakampani opanga magalimoto; ntchito ngati refrigerant , Makamaka mu LNG liquefaction zomera. Kusamala posungira: Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino. Khalani kutali ndi gwero la moto ndi kutentha. Kutentha kosungirako sikuyenera kupitirira 30°C. Iyenera kusungidwa mosiyana ndi ma okosijeni ndi ma halojeni, ndikupewa kusungirako kosakanikirana. Gwiritsani ntchito magetsi osaphulika komanso mpweya wabwino. Ndizoletsedwa kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kuphulika. Malo osungiramo zinthu ayenera kukhala ndi zida zothandizira zadzidzidzi zomwe zatuluka.

Ntchito:

①Makina:

Wapakati pamakampani opanga mankhwala ndikupanga mapulasitiki

②Chakudya:

Kucha kwa zipatso, makamaka nthochi..

③Galasi:

Galasi yapadera yamagalimoto agalimoto (galasi lamagalimoto).

④ Kupanga:

Kudula zitsulo, kuwotcherera ndi Kupopera Kwapamwamba Kwambiri Kutentha Kwambiri.

⑤Firiji:

Refrigerant makamaka mu LNG liquefaction zomera.

⑥Pulasitiki:

Amagwiritsidwa ntchito pochotsa mphira.

Phukusi labwinobwino:

Ubwino:

①Kuyera kwakukulu, malo aposachedwa;

② ISO wopanga satifiketi;

③Kutumiza mwachangu;

④Dongosolo lowunikira pa intaneti pakuwongolera kwamtundu uliwonse;

⑤Kufunika kwakukulu ndi njira yosamala yogwiritsira ntchito silinda musanadzaze;
