Mea hoʻokuʻu aku ma ka pūnaewele Kina CAS: 74-86-2, Acetylene

ʻO kā mākou holomua e pili ana i nā huahana holomua, nā talena kupaianaha a me ka hoʻoikaika mau ʻana i nā mana ʻenehana no ka mea hoʻokuʻu aku ma ka pūnaewele Kina CAS: 74-86-2, Acetylene, Ke ʻimi nei mākou i ka laulima nui me nā mea kūʻai aku ʻoiaʻiʻo, e hoʻokō ana i kahi kumu hou o ka hanohano me nā mea kūʻai aku a me nā hoa hana hoʻolālā.
ʻO kā mākou holomua e pili ana i nā huahana holomua, nā talena kupaianaha a me ka hoʻoikaika mau ʻana i nā mana ʻenehana noKinoea ʻAsetilena, ʻAsetilena Kina, E pili kā mākou hui i ka manaʻo ʻoihana "ʻO ka maikaʻi mua,, hemolele mau loa, hoʻonohonoho ʻia i nā kānaka, hana hou ʻenehana". Hana nui e hoʻomau i ka holomua, hana hou i ka ʻoihana, e hana i nā hana āpau i ka ʻoihana papa mua. Hoʻāʻo mākou i ka maikaʻi loa e kūkulu i ke kumu hoʻohālike hoʻokele ʻepekema, e aʻo i ka ʻike ʻoihana he nui, e hoʻomohala i nā lako hana holomua a me ke kaʻina hana, e hana i nā huahana a me nā hoʻonā maikaʻi mua, ke kumukūʻai kūpono, ke ʻano kiʻekiʻe o ka lawelawe, ka lawe wikiwiki ʻana, e hāʻawi iā ʻoe e hana i ka waiwai hou.

Nā palena loea

ʻO ka Acetylene, ka molekala C2H2, i ʻike nui ʻia ʻo ka lanahu makani a i ʻole ke kinoea calcium carbide, ʻo ia ka lālā liʻiliʻi loa o nā hui alkyne. ʻO ka Acetylene kahi kinoea ʻawaʻawa ʻole, ʻawaʻawa iki a hiki ke lapalapa loa me nā hopena anesthetic a me nā hopena anti-oxidation nāwaliwali ma lalo o ka mahana a me ke kaomi maʻamau. He mea hoʻoheheʻe iki ia i ka wai, hoʻoheheʻe ʻia i loko o ka ethanol, benzene, a me ka acetone. ʻAʻohe ʻala o ka acetylene maʻemaʻe, akā he ʻala kālika ka acetylene ʻoihana no ka mea aia nā mea haumia e like me ka hydrogen sulfide a me ka phosphine. ʻO ka acetylene maʻemaʻe kahi kinoea ʻawaʻawa ʻole a ʻala. Hiki ke pahū ikaika i ke ʻano wai a me ka paʻa a i ʻole ke ʻano kinoea a me kekahi kaomi. ʻO nā mea e like me ka wela, ka haʻalulu, a me ka ʻālohilohi uila hiki ke hana i ka pahū, no laila ʻaʻole hiki ke hoʻoheheʻe ʻia ma lalo o ke kaomi. Mālama a lawe paha. Ma 15°C a me 1.5MPa, kiʻekiʻe loa ka solubility i ka acetone, me ka solubility o 237g/L, no laila ʻo ka acetylene ʻoihana he acetylene i hoʻoheheʻe ʻia i loko o ka acetone, i kapa ʻia hoʻi he acetylene i hoʻoheheʻe ʻia. No laila, i loko o ka ʻoihana, i loko o nā cylinders kila i piha i nā mea porous e like me ka asbestos, ua kaomi ʻia ka acetylene i loko o ka mea porous ma hope o ka omo ʻana i ka acetone no ka mālama ʻana a me ka lawe ʻana. Hiki i ke kinoea acetylene ke hana i ka mahana kiʻekiʻe ke puhi ʻia. Hiki i ka mahana o ka lapalapa oxyacetylene ke hiki i kahi o 3200 ℃. Hoʻohana pinepine ʻia no ka ʻoki ʻana i ka metala e like me ke kūkulu moku a me ke kūkulu kila; hoʻohana ʻia no ka synthesis organik (hana ʻana i ka acetaldehyde, acetic acid, benzene, synthetic rubber, synthetic fibers, etc.), lāʻau lapaʻau synthetic a me nā mea waena kemika vinyl acetylene a i ʻole divinyl acetylene; hoʻohana ʻia e hana i nā kinoea maʻamau e like me ka loiloi ʻaila transformer maʻamau. Hoʻohana ʻia ke kinoea acetylene maʻemaʻe kiʻekiʻe no ka omo ʻana o ka atomic a me nā mea hana ʻē aʻe. Hoʻoheheʻe pinepine ʻia ke ʻano hoʻopili o ka acetylene i nā mea hoʻoheheʻe a me nā mea porous a hoʻopiha ʻia i loko o nā cylinders kila. E mālama i loko o kahi hale kūʻai anuanu a ventilated. E mālama mamao mai ke ahi a me nā kumu wela. ʻAʻole pono e ʻoi aku ka mahana o ka mālama ʻana ma mua o 30°C. Pono e mālama ʻokoʻa ʻia mai nā oxidants, nā waikawa, a me nā halogens, a pale i ka mālama ʻana i hui pū ʻia. E hoʻohana i nā kukui pale pahū a me nā hale ea. Ua pāpā ʻia ka hoʻohana ʻana i nā lako mīkini a me nā mea hana e hiki ke hoʻopili ʻia e nā huna ahi. Pono e hoʻolako ʻia kahi mālama me nā lako hana lapaʻau ulia pōpilikia liki.

Noi:

①ʻOki a me ka hoʻoheheʻe ʻana i ka metala:

Ke puhi ʻia ka acetylene, hiki iā ia ke hoʻopuka i ka mahana kiʻekiʻe. Hiki i ka mahana o ka lapalapa oxyacetylene ke piʻi ma kahi o 3200℃, kahi mea i hoʻohana ʻia no ka ʻoki ʻana a me ka hoʻoheheʻe ʻana i nā metala.

②Nā mea maka kemika kumu:

ʻO Acetylene ka mea nui no ka hana ʻana i ka acetaldehyde, acetic acid, benzene, synthetic rubber, a me nā fibers synthetic.

③ Hoʻokolohua

Hiki ke hoʻohana ʻia ka acetylene maʻemaʻe kiʻekiʻe i kekahi mau hoʻokolohua.
