Phosphorous Acid, pawiri pawiri ndi mankhwala chilinganizo H3PO3.Ndi woyera crystalline ufa, mosavuta sungunuka m'madzi ndi Mowa, ndipo pang'onopang'ono oxidized mu orthophosphate mu mpweya.Phosphite ndi dibasic acid, acidity yake ndi yamphamvu pang'ono kuposa phosphoric acid, imakhala ndi mphamvu yochepetsera, yosavuta kuchepetsa ayoni asiliva (Ag +) ku zitsulo zasiliva (Ag), imatha kuchepetsa sulfuric acid kukhala sulfure dioxide.Imakhala ndi hygroscopicity yolimba komanso yonyansa, ndipo imawononga.Phosphite imagwiritsidwa ntchito ngati chochepetsera, chowunikira nayiloni, komanso imagwiritsidwanso ntchito ngati zopangira za phosphite, mankhwala ophera tizilombo komanso othandizira madzi a phosphorous.
Katundu:woyera crystalline ufa.Kusungunuka m'madzi ndi mowa. Kachulukidwe: 1.651g/cm3, malo osungunuka: 73 ℃, malo otentha: 200 ℃.
APPLICATION:
1.Phosphorous acidamagwiritsidwa ntchito kupanga feteleza phosphate mchere monga potaziyamu phosphite, ammonium phosphite ndi calcium phosphite.Amagwira nawo ntchito yokonza ma phosphites monga aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) ndi 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), omwe amapeza kugwiritsa ntchito madzi ngati sikelo kapena zoletsa zowononga.Amagwiritsidwanso ntchito muzochita za mankhwala monga kuchepetsa.Mchere wake, lead phosphite umagwiritsidwa ntchito ngati PVC stabilizer.Amagwiritsidwanso ntchito ngati kalambulabwalo pokonza phosphine komanso ngati wapakatikati pokonzekera mankhwala ena a phosphorous.
2.Phosphorous acid(H3PO3, orthophosphorous acid) ingagwiritsidwe ntchito ngati imodzi mwazinthu zomwe zimapangidwira pakuphatikiza zotsatirazi:
α-aminomethylphosphonic acids kudzera mu Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids kudzera pa amidoalkylation yotsatiridwa ndi hydrolysis
N-protected α-aminophosphonic acids (phospho-isosteres of natural amino acids) kudzera mu amidoalkylation reaction
3. Ntchito zamafakitale: Wotolerayu adapangidwa posachedwa ndipo adagwiritsidwa ntchito makamaka ngati otolera ma cassiterite kuchokera ku ore okhala ndi zovuta za gangue. Pamaziko a phosphonic acid, Albright ndi Wilson adapanga otolera angapo makamaka pakuyandama kwa mchere wa okosijeni. ie cassiterite, ilmenite ndi pyrochlore).Zochepa kwambiri zimadziwika ponena za ntchito ya osonkhanitsawa.Kafukufuku wochepa wopangidwa ndi cassiterite ndi rutile ores adawonetsa kuti ena mwa otolerawa amatulutsa fungo lowala koma amasankha kwambiri.
Njira yopangira:
Njira zopangira mafakitale zimaphatikizapo trichloroic phosphorous ndi mchere wa phosphoric acid.Njira ya hydrolysis pang'onopang'ono imawonjezera madzi ku hydrolysis anachita pansi pa kusakaniza kwa trichloride kupanga sub-phosphoric acid.Pambuyo kuyenga, ChemicalBook yozizira, crystallization ndi ma discoloration amapangidwa, ndipo chomalizidwacho chimapangidwa.PCI3 + 3H2O yake → H3PO3 + 3HCL imapanga hydrogen chloride recycling panthawi yopanga, yomwe ingapangidwe kukhala hydrochloric acid.
Chitetezo:
Kuyaka chiopsezo makhalidwe: mu H dzenje wothandizira kuyaka;Kutentha kumawononga utsi woopsa wa phosphorous oxide.
Kusungirako ndi mayendedwe makhalidwe: nyumba yosungiramo mpweya mpweya otsika kutentha youma;Sungani mosiyana ndi H pore-release agent ndi alkali.
Kunyamula: 25kg / Thumba
Kusungirako: Sungani pamalo otsekedwa bwino, osamva kuwala, komanso kuteteza ku chinyezi.
