Asidi ya Phosphorous，chosakaniza chosapangidwa ndi mankhwala H3PO3. Ndi ufa woyera wa kristalo, womwe umasungunuka mosavuta m'madzi ndi ethanol, ndipo umasungunuka pang'onopang'ono kukhala orthophosphate mumlengalenga. Phosphite ndi dibasic acid, acidity yake ndi yamphamvu pang'ono kuposa phosphoric acid, ili ndi mphamvu yochepetsera mphamvu, ma ayoni asiliva (Ag+) osavuta kuchepetsa kukhala siliva (Ag), imatha kuchepetsa sulfuric acid kukhala sulfure dioxide. Ili ndi hygroscopicity yamphamvu komanso kumasuka, ndipo imawononga. Phosphite imagwiritsidwa ntchito kwambiri ngati chochepetsera mphamvu, chowunikira cha nayiloni, komanso imagwiritsidwa ntchito ngati zopangira za phosphite, mankhwala ophera tizilombo komanso zinthu zopangira organic phosphorous m'madzi.
Katundu:Ufa woyera wa kristalo. Sungunuka m'madzi ndi mowa. Kuchuluka: 1.651g/cm3, malo osungunuka: 73℃, malo owira: 200℃.
NTCHITO:
1.Asidi ya phosphorousimagwiritsidwa ntchito popanga feteleza wa phosphate salt monga potassium phosphite, ammonium phosphite ndi calcium phosphite. Imagwira ntchito kwambiri popanga ma phosphite monga aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) ndi 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), omwe amagwiritsidwa ntchito pochiza madzi ngati sikelo kapena choletsa kuwonongeka. Imagwiritsidwanso ntchito mu zochita za mankhwala ngati chochepetsera. Mchere wake, lead phosphite imagwiritsidwa ntchito ngati PVC stabilizer. Imagwiritsidwanso ntchito ngati choyambira pokonzekera phosphine komanso ngati chothandizira pokonzekera mankhwala ena a phosphorous.
2.Asidi ya phosphorous(H3PO3, orthophosphorous acid) ingagwiritsidwe ntchito ngati chimodzi mwa zigawo zomwe zimayambitsa kupanga zotsatirazi:
α-aminomethylphosphonic acids kudzera mu Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids kudzera mu amidoalkylation kenako ndi hydrolysis
Ma α-aminophosphonic acids otetezedwa ndi N (phospho-isosteres a amino acids achilengedwe) kudzera mu amidoalkylation reaction
3. Ntchito Zamakampani: Chosonkhanitsa ichi chapangidwa posachedwapa ndipo chimagwiritsidwa ntchito makamaka ngati chosonkhanitsa chapadera cha cassiterite kuchokera ku miyala yokhala ndi kapangidwe ka gangue kovuta. Pogwiritsa ntchito phosphonic acid, Albright ndi Wilson adapanga mitundu yosiyanasiyana ya zosonkhanitsa makamaka kuti zizitha kuyandama kwa mchere wa oxidic (monga cassiterite, ilmenite ndi pyrochlore). Palibe zambiri zomwe zimadziwika za momwe osonkhanitsa awa amagwirira ntchito. Kafukufuku wochepa wochitidwa ndi miyala ya cassiterite ndi rutile wasonyeza kuti ena mwa osonkhanitsawa amapanga thovu lalikulu koma anali osankha kwambiri.
Njira yopangira:
Njira zopangira mafakitale zimaphatikizapo trichloroic phosphoric acid ndi mchere wa phosphoric acid. Njira ya hydrolysis imawonjezera madzi pang'onopang'ono ku hydrolysis reaction pansi pa kusakaniza kwa trichloride kuti apange sub-phosphoric acid. Pambuyo poyenga, ChemicalBook yozizira, makristalo ndi kusintha kwa mtundu zimapangidwa, ndipo chinthu chomalizidwa chimapangidwa. PCI3+3H2O → H3PO3+3HCL yake imapanga hydrogen chloride recycling panthawi yopanga, yomwe ingapangidwe kukhala hydrochloric acid.
Chitetezo:
Zizindikiro za chiopsezo choyaka: mu dzenje la H chinthu chomwe chimayaka; Kutentha kumawononga utsi woopsa wa phosphorous oxide.
Makhalidwe osungira ndi mayendedwe: mpweya wolowera m'nyumba yosungiramo zinthu umakhala wouma pang'ono; Sungani padera ndi chotulutsira ma pore a H ndi alkali.
Kulongedza: 25kg/Chikwama
Kusunga: Sungani pamalo otsekedwa bwino, osapsa ndi kuwala, komanso chitetezeni ku chinyezi.
