Phosphorous acid, wani inorganic fili tare da sinadaran dabara H3PO3.Farin foda ne na crystalline, mai sauƙi mai narkewa a cikin ruwa da ethanol, kuma sannu a hankali oxidized zuwa orthophosphate cikin iska.Phosphite shine acid dibasic, acidity ɗinsa ya ɗan fi ƙarfin phosphoric acid, yana da ƙarfi rage dukiya, mai sauƙin rage ions na azurfa (Ag +) zuwa ƙarfe na azurfa (Ag), na iya rage sulfuric acid zuwa sulfur dioxide.Yana da karfi hygroscopicity da deliviousness, kuma yana da lalata.Ana amfani da Phosphite galibi azaman wakili mai ragewa, nailan mai haskakawa, amma kuma ana amfani dashi azaman albarkatun phosphite, tsaka-tsakin magungunan kashe qwari da ma'aikatan jiyya na ruwa na phosphorus.
Kaddarori:farin crystalline foda.Mai narkewa cikin ruwa da barasa.Yawan: 1.651g/cm3, narkewa: 73 ℃, tafasar batu: 200 ℃.
APPLICATION:
1.Phosphorous acidAna amfani dashi don samar da gishiri phosphate taki kamar potassium phosphite, ammonium phosphite da calcium phosphite.Yana da hannu sosai a cikin shirye-shiryen phosphites kamar aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) da 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), wanda ya samo. aikace-aikace a cikin maganin ruwa a matsayin ma'auni ko mai hana lalata.Hakanan ana amfani dashi a cikin halayen sunadarai azaman wakili mai ragewa.Gishirin sa, gubar phosphite ana amfani dashi azaman stabilizer na PVC.Hakanan ana amfani dashi azaman mafari a cikin shirye-shiryen phosphine kuma a matsayin matsakaici a cikin shirye-shiryen sauran mahadi na phosphorus.
2.Phosphorous acid(H3PO3, orthophosphorous acid) ana iya amfani dashi azaman ɗaya daga cikin abubuwan da aka haɗa don haɗar abubuwa masu zuwa:
α-aminomethylphosphonic acid ta hanyar Mannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acid ta hanyar amidoalkylation ta hanyar hydrolysis
N-kariyar α-aminophosphonic acid (phospho-isosteres na amino acid na halitta) ta hanyar amsawar amidoalkylation.
3. Masana'antu amfani: Wannan mai tarawa da aka ɓullo da kwanan nan da aka yi amfani da farko a matsayin musamman mai tarawa ga cassiterite daga ores tare da hadaddun gangue abun da ke ciki.On tushen da phosphonic acid, Albright da Wilson sun ɓullo da wani kewayon masu tarawa, yafi ga flotation na oxidic ma'adanai ( watau cassiterite, ilmenite da pyrochlore).An san kadan game da ayyukan waɗannan masu tarawa.Ƙayyadaddun bincike da aka gudanar tare da cassiterite da rutile ores sun nuna cewa wasu daga cikin waɗannan masu tarawa suna samar da kumfa mai yawa amma sun kasance masu zaɓaɓɓu.
Hanyar samarwa:
Hanyoyin samar da masana'antu sun haɗa da trichloroic phosphorus da phosphoric acid gishiri.Hanyar hydrolysis sannu a hankali yana ƙara ruwa zuwa yanayin hydrolysis a ƙarƙashin hadawar trichloride don samar da sub-phosphoric acid.Bayan tacewa, sanyi ChemicalBook, ana yin crystallization da discoloration, kuma an yi samfurin da aka gama.PCI3+3H2O → H3PO3+3HCL yana samar da sake amfani da hydrogen chloride yayin aikin samarwa, wanda za'a iya sanya shi ya zama hydrochloric acid.
Tsaro:
Halayen haɗarin flammability: a cikin wakili mai ƙonewa na H rami;Zafi yana lalata tururin phosphorus oxide mai guba.
Halayen ajiya da sufuri: sharar iska mai ƙarancin zafin jiki bushe;Ajiye daban daga wakili mai sakin H pore da alkali.
Shiryawa: 25kg/Bag
