Ntchito Yogulitsa:
1.Ethanol ndizofunikira kwambiri zosungunulira organic, zomwe zimagwiritsidwa ntchito kwambiri mu mankhwala, utoto, ukhondo, zodzoladzola, mafuta ndi mafuta ndi njira zina, zomwe zimawerengera pafupifupi 50% ya mowa wonse wa ethanol.Mowa ndi zofunika zofunika mankhwala zopangira, ntchito kupanga acetaldehyde, ethylene diene, ethylamine, ethyl acetate, asidi asidi, chloroethane, etc., ndipo anachokera ku intermediates ambiri mankhwala, utoto, utoto, zonunkhira, kupanga mphira, zotsukira. , mankhwala ophera tizilombo, etc., ndi mitundu yoposa 300 ya mankhwala, koma tsopano ntchito Mowa monga mankhwala intermediates mankhwala akuchepa pang'onopang'ono, ndipo mankhwala ambiri, monga acetaldehyde, asidi asidi, ethyl mowa, alibenso ntchito Mowa monga zopangira, koma ethyl mowa ngati zopangira.Komabe, kugwiritsidwa ntchito kwa ethanol monga mankhwala apakatikati kumachepa pang'onopang'ono, ndipo zinthu zambiri monga acetaldehyde, acetic acid, ethyl mowa sakugwiritsanso ntchito ethanol monga zopangira, koma zimasinthidwa ndi zipangizo zina.Mwapadera woyengedwa Mowa amagwiritsidwanso ntchito popanga zakumwa.Mofanana ndi methanol, ethanol ingagwiritsidwe ntchito ngati gwero la mphamvu.Mayiko ena ayamba kugwiritsa ntchito ethanol yokha ngati mafuta agalimoto kapena ophatikizana ndi mafuta (10% kapena kupitilira apo) kuti apulumutse mafuta.
2.Kugwiritsidwa ntchito ngati zosungunulira zomatira, utoto wa nitro spray, varnishes, zodzoladzola, inki, zojambula zopaka utoto, ndi zina zotero, komanso zopangira zopangira mankhwala ophera tizilombo, mankhwala, rubbers, mapulasitiki, fibers synthetic, detergents, etc. , ndi monga antifreeze, mafuta, mankhwala ophera tizilombo ndi zina zotero.M'makampani opanga ma microelectronics, omwe amagwiritsidwa ntchito ngati mankhwala ochotsera madzi ndi decontamination, angagwiritsidwe ntchito pamodzi ndi degreasing agent.
3.Used as analytical reagent, monga zosungunulira.Amagwiritsidwanso ntchito m'makampani opanga mankhwala.
4.Kugwiritsidwa ntchito pamakampani amagetsi, ogwiritsidwa ntchito ngati ochotsera madzi otsekemera ndi otsekemera komanso osakaniza zosakaniza.
5.Kugwiritsidwa ntchito kusungunula zina zosasungunuka za electroplating organic additives, zomwe zimagwiritsidwanso ntchito ngati hexavalent chromium reduction agent mu analytical chemistry.
6.Used mu makampani vinyo, organic synthesis, disinfection ndi monga zosungunulira.
Zolemba Zosungira:
1.Sungani m'nyumba yosungiramo zoziziritsa komanso mpweya wabwino.
2. Khalani kutali ndi moto ndi gwero la kutentha.
3.Kutentha kosungirako kusapitirire 37°C.
4.Sungani chidebe chosindikizidwa.
5.Iyenera kusungidwa mosiyana ndi oxidants, acids, alkali zitsulo, amines, etc., osasakaniza zosungirako.
6.Gwiritsani ntchito zounikira zosaphulika ndi mpweya wabwino.
7.Letsani kugwiritsa ntchito zida zamakina ndi zida zomwe zimakhala zosavuta kupanga zopsereza.
8.Malo osungira ayenera kukhala ndi zida zowonongeka zowonongeka ndi zipangizo zoyenera zogona.
