Hydrogen Sulfide (H2S)

Nā palena ʻenehana

ʻO ka hydrogen sulfide kahi pūhui inorganic me kahi ʻano mole o H2S a me ke kaumaha molekala o 34.076. Ma lalo o nā kūlana maʻamau, he kinoea ʻakika hiki ke ahi. ʻAʻohe kala a loaʻa ke ʻala o nā hua popopo ma nā haʻahaʻa haʻahaʻa. ʻawaʻawa. ʻO ka hoʻonā wai he hydrogen sulfuric acid, ʻoi aku ka nāwaliwali ma mua o ka waikawa carbonic, akā ʻoi aku ka ikaika ma mua o ka waikawa boric. Hiki ke hoʻoheheʻe ʻia ka hydrogen sulfide i ka wai, hiki ke hoʻoheheʻe ʻia i loko o nā ʻawaʻawa, nā mea hoʻoheheʻe aila a me ka aila maʻemaʻe, a ʻaʻole paʻa kona mau mea kemika. ʻO ka hydrogen sulfide ka mea hiki ke puhi a me ka weliweli. Ke hui pū ʻia me ka ea, hiki ke hana i kahi hui pahū. Hiki iā ia ke hana i ka puhi ahi a me ka pahū ke ʻike ʻia i nā lapalapa a me ka wela nui. He mea ʻawaʻawa loa ia. Loaʻa nā hopena o ka hydrogen sulfide haʻahaʻa i nā maka, ka ʻōnaehana hanu a me ke ʻano o ka ʻōpū. ʻO ka inhalation o kahi liʻiliʻi o ka hydrogen sulfide kiʻekiʻe hiki ke make i ka manawa pōkole. Hoʻohana ʻia i ka hana ʻana i nā phosphors synthetic, electroluminescence, photoconductors, photoelectric exposure meters, etc. Organic synthesis reducing agent. Hoʻohana ʻia no ka hoʻomaʻemaʻe metala, pesticides, lāʻau lapaʻau, catalyst regeneration. Nā mea hoʻopaʻa maʻamau. Ka hoʻomākaukau ʻana i nā sulfide like ʻole. Hoʻohana ʻia i ka hana ʻana i nā sulfides inorganic, a hoʻohana ʻia hoʻi i ka loiloi kemika e like me ka ʻike ʻana i nā ion metala. Hoʻohana ʻia ka hydrogen sulfide kiʻekiʻe i ka semiconductor a me nā māla ʻē aʻe. Hiki ke hoʻohana ʻia i loko o ka ʻoihana kemika pale aupuni, ka lāʻau lapaʻau a me ka pesticide intermediates, non-ferrous metala hoʻomaʻemaʻe a me ka metala hoʻololi ʻana i ka mālama ʻana, hoʻohana ʻia i ka hoʻomākaukau ʻana i ke kinoea maʻamau, calibration kinoea, a me ka loiloi kemika e like me ka ʻike ʻana o nā ion metala. ʻO kahi mea waiwai nui no ka hana ʻana i nā mea optical infrared. E mālama i ka mālama ʻana: E kūʻai i loko o kahi hale kūʻai ʻoluʻolu. E mālama i ke ahi a me nā kumu wela. ʻAʻole pono ka mahana o ka mālama ʻana ma mua o 30 ° C. Paʻa paʻa ka ipu. Pono e mālama kaʻawale ʻia mai nā oxidants a me nā alkalis, a pale i ka waiho ʻana. E hoʻohana i nā kukui pahū a me nā keʻena ea. ʻAʻole ʻae ʻia ka hoʻohana ʻana i nā mea hana mechanical a me nā mea hana e maʻalahi i nā huna ahi. Pono e hoʻolako ʻia ka wahi e mālama ai me nā lako lapaʻau ulia pōpilikia.

Noi:

①Ka hana ʻana o nā pūhui thioorganic:

Hana ʻia kekahi mau pūhui organosulfur me ka hydrogen sulfide. ʻO kēia mau methanethiol, ethanethiol, a me thioglycolic acid.

②Kemika analytical:

No hoʻokahi haneli, he mea koʻikoʻi ka hydrogen sulfide i ka kemika analytical, i ka qualitative inorganic analysis of metal ions.

③Precursor i metala sulfides:

E like me ka mea i hōʻike ʻia ma luna nei, nui nā iona metala e hana me ka hydrogen sulfide e hāʻawi i nā sulfides metala e pili ana.

④ Nā noi like ʻole:

Hoʻohana ʻia ka hydrogen sulfide e hoʻokaʻawale i ka deuterium oxide, a i ʻole ka wai kaumaha, mai ka wai maʻamau ma o ke kaʻina hana sulfide Girdler.

Pūʻolo maʻamau:

Pōmaikaʻi:

①Maʻemaʻe kiʻekiʻe, hale hana hou loa;

②Ka mea hana palapala ISO;

③Hoʻouna wikiwiki;

④Stable maka waiwai mai loko mai;

⑤ ʻO ka ʻōnaehana hoʻopaʻa inoa pūnaewele no ka hoʻokele maikaʻi ʻana i kēlā me kēia pae;

⑥Ke koi kiʻekiʻe a me ke kaʻina hana no ka mālama ʻana i ka cylinder ma mua o ka hoʻopiha ʻana;
