Phosphurous acid, I-inorganic ye-inorganic ngefomathi yekhemikhali h3po3. Yinto yomgubo we-crystalline emhlophe, inyibilikihla ngokulula emanzini nase-Ethanol, kwaye ihamba kancinci kwi-orthophofosphate emoyeni. I-phosfite yi-dibasic acid, i-acidity yayo yomelele kancinci kune-phosphoric acid, inepropathi eqinileyo, kulula ukunciphisa i-inish yesilivere (AG +) kwi-SILDFURIC AID DANOXIS. Inohlaselo olunamandla kunye nokuhlutha, kwaye kuyacaca. I-phosfite isetyenziswa ikakhulu njengokunciphisa iarhente yearhente, i-nylon ekhanyisayo, kodwa isetyenziswa njengezixhobo ze-phosfite, iyeza lezibulala-ntle kunye neearhente zonyango lwe-phophosa ye-phophosa ye-phophosa.
Iipropathi:I-rystalline yomgubo we-rystalline. Inyibilikiswa emanzini naselutyweni.dety: 1.651G / cm3, inqaku elinyibilikayo: 73 ℃, i-airtions: 200 ℃.
Isicelo:
1.Phosphurous acidisetyenziselwa ukuvelisa i-phertilizer phot ityiwa njenge-potassium phosfite, i-Ammonium phesfite kunye ne-calcium phosfite. Ibandakanyekile ekulungiseleleni i-phosphites njenge-Amintospris (Methynenesphonion Abid) (I-ANPMP), i-1-Hydroxyene 1,1-diphononic acid-i-phosphononic acid (PBTC), efumana Isicelo kunyango lwamanzi njengesikali okanye i-corrosive invem. Ikwasetyenziswa kukuphendula kweekhemikhali njengearhente yokunciphisa. Ityiwa yayo, khokelela phosfite isetyenziswa njenge-pvc stabilizer. Ikwasetyenziswa njengentshabalalo kumalungiselelo e-phosphine kunye ne-phopript kwilungiselelo leminye imichiza ye phosphorus.
2.Phosphurous acid.

3. Usetyenziso lweshishini: Lo mqokeleli waphuhliswa kutshanje kwaye wasetyenziswa ikakhulu njengomqokeleli othile we-cassiterite kwi-ossoporations.On, i-Abright Acid iqulethe uluhlu lwabaqokeleli lwe-oxidic ( I-Cassiterite, ilmerite kunye ne-pyrochlore). Kuncinci kakhulu kuyaziwa malunga nokusebenza kwaba buqokeleli. Izifundo ezinomda oqhutywa kunye ne-cassiterite kunye nee-ores zibonisa ukuba abanye babaqokeleli bavelisa i-floumous bimputer kodwa babekhetha kakhulu.
Indlela yemveliso:
Iindlela zokuveliswa kwemizi-mveliso zibandakanya i-phosphorus ye-phosphorus ye-phosphorius kunye ne-phosphoric acid ityiwa. Indlela ye-hydrolysis kancinci iyongeza amanzi kwi-hydrolysis yokuphendula phantsi komxube we-Stichloric ukuze ivelise i-sub -phophoric acid. Emva kokuhlaziywa, kubanda iikhemikhali zekhemikhali, i-crystallization kunye ne-discolotion yenziwa, kwaye imveliso egqityiweyo yenziwa. I-PCI3 + 3H2O → H3PO3 + 3HCL ivelisa i-hydrogen chloride yokuphinda isebenze ngexesha lenkqubo, enokwenziwa kwi-hydrochloric acid.
Ukhuseleko:
Iimpawu eziMngcipheko ukufunyanwa Ubushushu bubola i-phosphorius ye-phosphorois oxial.
Iimpawu zokugcina kunye nezothutho Gcina ngokwahlukeneyo kwi-HORE-Ukukhuphela iarhente kunye ne-alkali.
Ukupakisha: 25kg / ibhegi
Ukugcinwa: Gcina kwindawo evaliweyo, enganyangekiyo, kwaye ukhusele umswakama.
Ixesha lePosi: NgoFebruwari-27 ukuya ku-4023
