ʻO Ethylene (C2H4)

Nā palena kikoʻī

Ma lalo o nā kūlana maʻamau, he ʻenekini kala ʻole, a ʻaʻala liʻiliʻi hoʻi ka ethylene me ka nui o 1.178g / L, ʻoi aku ka liʻiliʻi o ka lewa ma mua o ka ea. ʻAneʻane hiki ʻole ke hoʻonā ʻia i ka wai, ʻaʻohe hiki ke hoʻoheheʻe ʻia i ka ethanol, a hiki ke hoʻoheheʻe iki ʻia i ka ethanol, ketones, a me benzene. , Wehe i ka ether, hiki ke maʻalahi ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻeolaola e like me carbon tetrachloride. ʻO Ethylene kekahi o nā huahana kemika me ka hoʻopuka nui loa ma ka honua. ʻO ka ʻoihana ethylene ke kumu o ka petrochemical ʻoihana. ʻOi aku nā huahana Ethylene ma mua o 75% o nā huahana petrochemical a noho i kahi kūlana koʻikoʻi i ka hoʻokele aupuni. Ua nānā ka honua i ka hana ʻana o ka ethylene ma ke ʻano he hōʻailona nui e ana i ka pae hoʻomohala o kahi ʻoihana petrochemical o kahi ʻāina. ʻO Ethylene kahi mea waiwai kemika waiwai nui i hoʻohana nui ʻia, hoʻohana nui ʻia i ka hana ʻana o polyethylene, kāpili propylene ethylene, polyvinyl chloride, a me nā mea ʻē aʻe ʻo Ethylene kekahi o nā mea maka no ka petrochemical ʻoihana. E pili ana i nā mea synthetic, hoʻohana ākea ia i ka hana o polyethylene, vinyl chloride, a pēlā aku. e pili ana i ka synthetic synthetic, hoʻohana ākea ia i ka synthesite o ka ethanol, ethylene oxide, ethylene glycol, acetaldehyde, a me propylene. Ke ʻano like ʻole o nā meaola synthetic kumu waiwai e like me aldehydes a me kā lākou mea e loaʻa ai; ma o ka halogenation, hiki iā ia ke hana i ka chloroethylene, chloroethane, bromoethane, a pēlā aku. Hoʻohana pū ʻia ʻo Ethylene ma ke ʻano he kinoea maʻamau no nā mea kālaiʻike i nā ʻoihana petrochemical; hoʻohana 'ia e like me ka environmentally aloha oo gas no nā hua e like me navel ʻalani, tangerines, maiʻa, a pela aku; hoʻohana ʻia i ka synthesi o nā lāʻau a me nā pono loea kiʻekiʻe; hoʻohana ʻia i ka hana ʻana o ke aniani kūikawā no ka ʻoihana kaʻa; hoʻohana ʻia e like me ka coolant, ʻOi aku i nā mea kanu liʻiliʻi ʻo LNG. Mālama i ka mālama ʻana: E mālama i kahi waihona hoʻoluʻu a hoʻoliʻiliʻi. E mālama i nā kumu ahi a me nā kumu wela. ʻAʻole iʻoi aku ka nui o ka mahana mālama ma mua o 30 ° C. Pono e mālama kaʻawale ʻia mai nā oxidants a me nā halogens, a pale i ka mālama hoʻohuihui. E hoʻohana i nā uila a me nā pono ea. Pāpā ʻia ka hoʻohana ʻana i nā pono mīkini a me nā pono hana e maʻalahi i nā huna ahi. Pono e hoʻolako ʻia kahi e waiho ai me nā lako hana hoʻopulapula leakage.
