1,2-Dichloroethane: He Kemika ʻOihana Versatile
Nā Kahua Noi Nui
I loko o ka ʻoihana kemika, ʻo ka hoʻohana nui ʻana o 1,2-dichloroethane ma ke ʻano he mea maka no ka hana ʻana i ka vinyl chloride. ʻO ka vinyl chloride kahi monomer koʻikoʻi i hoʻohana ʻia e hana i ka polyvinyl chloride (PVC), kahi plastik i hoʻohana nui ʻia i ke kūkulu ʻana, nā paipu, ka insulation uwea, a me nā mea hoʻopili. Eia kekahi, hiki ke hoʻololi ʻia ka 1,2-dichloroethane i acetylene ma o ka dehydrochlorination. He mea koʻikoʻi ka Acetylene no ka synthesis organik, i hoʻohana ʻia i ka hana ʻana o nā huahana kemika like ʻole e like me ka acetaldehyde, acetic acid, a me ka chloroprene rubber.
Ma ka ʻāpana solvent, ʻo 1,2-dichloroethane kahi solvent organik kūpono e hiki ke hoʻoheheʻe i nā ʻano hui organik a me nā polymers. Hoʻohana pinepine ʻia ia no ka hoʻomaʻemaʻe a me ka wehe ʻana i nā ʻili metala, ʻoi aku hoʻi i nā ʻoihana uila a me nā ʻoihana hana mechanical. Eia kekahi, hoʻohana ʻia ʻo 1,2-dichloroethane no ka wehe ʻana i ka pena a me ka uhi ʻana, a no ka hoʻomaʻemaʻe ʻana i nā lako paʻi ma ka ʻoihana paʻi.
I loko o nā ʻoihana pesticides a me nā ʻala, hoʻohana ʻia ʻo 1,2-dichloroethane ma ke ʻano he waena. Hiki ke hoʻohana ʻia e hana i nā pesticides like ʻole, e like me nā herbicides a me nā insecticides, i hoʻohana nui ʻia i ka mahiʻai. Eia kekahi, hiki ke hoʻohana ʻia ʻo 1,2-dichloroethane e hana i nā ʻala a me nā mea ʻono, i hoʻohana nui ʻia i nā ʻoihana meaʻai a me nā mea hoʻonani.
I ka mālama ʻana i ka wai, hoʻohana ʻia nā mea i loaʻa mai ka 1,2-dichloroethane, e like me ka polyethylene chlorinated, no ka hana ʻana i nā mea pale wai a me nā mea pale i ka pala. Hoʻohana nui ʻia kēia mau mea i nā mālama pale wai no nā hale a me nā lako ʻoihana, e pale pono ana i ke komo ʻana o ka wai a me ka pala.
ʻOiai kona ākea o nā noi ʻoihana, he mea ʻawahia ka 1,2-dichloroethane, a pono e mālama pono i nā lula palekana no kona hoʻohana ʻana. Hoʻohana pinepine ka hana ʻoihana i nā ʻōnaehana pani e hōʻemi i kona volatility a ua lako me nā ʻōnaehana ea a me ka mālama ʻana i ka hoʻopau ʻana e pale i ke olakino o ka limahana a me ka palekana o ke kaiapuni. Me ka hoʻonui ʻana i ka ʻike kaiapuni, ke hoʻomaikaʻi ʻia nei ke kaʻina hana o 1,2-dichloroethane e hōʻemi i kona hopena i ke kaiapuni.

I ka hōʻuluʻulu manaʻo
I ka hōʻuluʻulu manaʻo, ʻo 1,2-dichloroethane, ma ke ʻano he mea maka kemika organik versatile, he kūlana koʻikoʻi ia i ka ʻoihana. ʻAʻole ia e hiki ai ke hana i nā ʻano kemika koʻikoʻi like ʻole akā kākoʻo pū kekahi i ka hoʻomohala ʻana o ka ʻoihana hou. Me ka holomua mau ʻana o ka ʻenehana, e ʻoi aku ka laulā o nā manaʻolana noi no 1,2-dichloroethane.
