Hoʻohana huahana:
1. ʻO Ethanol kahi mea hoʻoheheʻe organik nui, hoʻohana nui ʻia i ka lāʻau lapaʻau, pena, nā huahana maʻemaʻe, nā mea hoʻonaninani, ka aila a me ka momona a me nā ʻano hana ʻē aʻe, e helu ana ma kahi o 50% o ka pau ʻana o ka ethanol.He mea koʻikoʻi ka ethanol, i hoʻohana ʻia i ka hana ʻana i ka acetaldehyde, ethylene diene, ethylamine, ethyl acetate, acetic acid, chloroethane, etc. , pesticides, etc., me ka oi aku ma mua o 300 ano o ka huahana, aka, i keia manawa, ke emi malie nei ka hoohana ana i ka ethanol ma ke ano he huahana kemika, a he nui na huahana, e like me ka acetaldehyde, acetic acid, ethyl alcohol, aole i hoohana hou i ka ethanol ma ke ano he mea maka, akā ethyl alcohol ma ke ano he mea maka.Eia naʻe, ke emi mālie nei ka hoʻohana ʻana i ka ethanol ma ke ʻano kemika waena, a ʻo nā huahana he nui e like me acetaldehyde, acetic acid, ethyl alcohol ʻaʻole e hoʻohana hou ana i ka ethanol ma ke ʻano he mea maka, akā ua hoʻololi ʻia e nā mea maka.Hoʻohana ʻia ka ethanol i hoʻomaʻemaʻe kūikawā i ka hana ʻana i nā mea inu.E like me ka methanol, hiki ke hoʻohana ʻia ka ethanol ma ke ʻano he kumu ikehu.Ua hoʻomaka kekahi mau ʻāina e hoʻohana i ka ethanol ma ke ʻano he wahie kaʻa a i hui pū ʻia i loko o ka ʻaila (10% a ʻoi aʻe paha) e mālama ai i ka ʻaila.
2. Hoʻohana ʻia ma ke ʻano he mea hoʻoheheʻe no ka hoʻopili ʻana, nā peʻa nitro spray, varnish, cosmetics, inks, paint strippers, etc., a me kahi mea maka no ka hana ʻana i nā pesticides, lāʻau lapaʻau, rubbers, plastics, synthetic fibers, detergents, etc. , a me he antifreeze, wahie, disinfectant a pela aku.I loko o kaʻoihana microelectronics, i hoʻohanaʻia e like me ka mea hoʻoheheʻe a me ka hoʻopauʻana, hiki ke hoʻohanaʻia me ka mea hoʻoheheʻe.
3.Used e like me analytical reagent, e like me ka solvent.Hoʻohana pū ʻia i ka ʻoihana lāʻau lapaʻau.
4.Hoʻohanaʻia i loko o kaʻoihana uila, hoʻohanaʻia e like me ka mea hoʻoheheʻe a me ka mea hoʻoheheʻe a me nā mea hoʻoheheʻe degreasing.
5.Used e hoʻoheheʻe i kekahi insoluble electroplating organic additives, i hoʻohana 'ia e like me hexavalent chromium ho'ēmi 'ana i ka analytical kemika.
6.Hoʻohana ʻia i ka ʻoihana waina, ka synthesis organik, disinfection a me ka mea hoʻoheheʻe.
Nā memo mālama huahana:
1. E kūʻai i loko o kahi hale kūʻai ʻoluʻolu.
2.E mālama i ke ahi a me ke kumu wela.
