Helu CAS 7803-51-2 Mea Hoʻolako Phosphine. Nā ʻano o ka Phosphine

ʻO ka Phosphine (PH₃) he kinoea waihoʻoluʻu ʻole a hiki ke hoʻā ʻia me ka ʻala iʻa he mea ʻawaʻawa loa i ke kanaka. Ua like ia me ka ammonia (NH₃), akā ʻoi aku ka liʻiliʻi o ke kumu a ʻoi aku ka ʻoi aku o ka hana. Hoʻohana ʻia ka Phosphine i nā noi ʻoihana like ʻole, me ka ʻoihana semiconductor no ka doping silicon a me gallium arsenide, i ka hana ʻana i nā phosphides metala, a ma ke ʻano he fumigant i ka mahiʻai.

Eia kekahi mau hiʻohiʻona nui o ka phosphine:

Nā waiwai kemika:
ʻAno molekole: PH₃
Kaumaha Molekala: 33.99776 g/mol
Helu CAS: 7803-51-2
Puni paila: -87.8 °C
Ka helu hehee: -133.3 °C
Māmā: 1.634 g/L ma STP (mehana maʻamau a me ke kaomi)
Nā waiwai kino:
He kinoea kala ʻole ka Phosphine ma ka lumi wela a me ke kaomi.
Hiki ke ʻā a hiki ke ʻā wale ke ʻike ʻia i ka ea ma muli o kona ʻano kiʻekiʻe.
ʻona:
He mea ʻawaʻawa loa ka Phosphine ma ka hoʻohu ʻia ʻana, e hōʻeha nui ai i ka māmā a hiki i ka make.
He mea ʻawaʻawa hoʻi ke ʻai ʻia a komo ʻia paha ma ka ʻili.
Hoʻohana:
I ka hana semiconductor no ka hana doping.
Ma ke ʻano he fumigant i ka waiho ʻana i ka palaoa no ka hoʻopaʻa ʻana i nā pests.
I ka synthesis o nā pūhui organophosphorus.
Ka mālama ʻana a me ka mālama ʻana:
Pono e mālama ʻia ka Phosphine me ka mālama nui ma muli o kona ʻona a me ka flammability.
Pono e mālama ʻia ma kahi maloʻo maloʻo ma kahi mamao mai kahi kumu e hoʻā ai.
Pono e mālama pono ʻia e pale aku i ka leak a i ʻole ke kahe.
Loaʻa iā Shanghai Wechem Chemical Co., Ltd. nā mea hana kiʻekiʻe a me ka ʻenehana analytical i loko o kāna hale hana, e hōʻoia ana e hiki iā mākou ke hoʻokō pololei i ka mana o ka huahana a me ka hoʻāʻo. Hoʻohana mākou i kahi ʻōnaehana hoʻokele maikaʻi koʻikoʻi, ka nānā ʻana a me ka hoʻokele ʻana i kēlā me kēia hana mai ke kūʻai ʻana i nā mea waiwai a hiki i ka hana ʻana e hōʻoia i nā huahana a mākou e hoʻolako ai i nā kūlana kiʻekiʻe loa. Inā makemake ʻoe i kēia huahana, e ʻoluʻolu e kelepona iā mākou i kēlā me kēia manawa!
