Asidhi yePhosphorous，chinhu chisina kugadzirwa chine fomura yemakemikari H3PO3. Iupfu hwemakristaro machena, hunonyungudika nyore nyore mumvura uye mune ethanol, uye hunosanganiswa zvishoma nezvishoma kuita orthophosphate mumhepo. Phosphite idibasic acid, acidity yayo yakasimba zvishoma pane phosphoric acid, ine simba rekudzikisa, iri nyore kuderedza maion esirivha (Ag+) kuita sirivha simbi (Ag), inogona kuderedza sulfuric acid kuita sulfur dioxide. Ine hygroscopicity yakasimba uye deliviousness, uye inoparadza. Phosphite inonyanya kushandiswa se reduction agent, nylon brightening agent, asiwo inoshandiswa se phosphite raw materials, pesticide intermediates uye organic phosphorus water treatment agents raw materials.
Zvivakwa:Upfu hwemakristaro machena. Hunonyungudika mumvura nedoro. Huremu: 1.651g/cm3, nzvimbo yekunyunguduka: 73℃, nzvimbo yekufashaira: 200℃.
KUSHANDISA:
1.Asidhi yePhosphorousInoshandiswa kugadzira munyu wephosphate wefosfeti se potassium phosphite, ammonium phosphite uye calcium phosphite. Inobatanidzwa zvakanyanya mukugadzirwa kwemaphosphite akadai se aminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) uye 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), ayo anoshandiswa mukurapa mvura sechikero kana chinodzivirira ngura. Inoshandiswawo mumakemikari semushonga unodzikisa. Munyu wayo, lead phosphite inoshandiswa sePVC stabilizer. Inoshandiswawo senzira yekutanga mukugadzirwa kwephosphine uye senzira yepakati mukugadzirwa kwemamwe macompounds e phosphorus.
2.Asidhi yePhosphorous(H3PO3, orthophosphorous acid) inogona kushandiswa seimwe yezvikamu zve reaction pakugadzira zvinotevera:
α-aminomethylphosphonic acids kuburikidza neMannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids kuburikidza ne amidoalkylation ichiteverwa ne hydrolysis
Ma-α-aminophosphonic acids akachengetedzwa neN (phospho-isosteres yemaamino acids echisikigo) kuburikidza neamidoalkylation reaction
3. Mashandisirwo emaindasitiri: Muunganidzi uyu wakagadzirwa nguva pfupi yadarika uye wainyanya kushandiswa semuunganidzi chaiwo we cassiterite kubva mumatombo ane gangue complex. Zvichibva pa phosphonic acid, Albright naWilson vakagadzira mhando dzakasiyana dzemuunganidzi kunyanya dzemuunganidzi we oxidic minerals (kureva cassiterite, ilmenite uye pyrochlore). Zvishoma zvinozivikanwa nezvekushanda kwemuunganidzi uyu. Zvidzidzo zvishoma zvakaitwa ne cassiterite ne rutile ores zvakaratidza kuti vamwe vevaunganidzi ava vanogadzira furo rakawanda asi vaisarudza zvakanyanya.
Nzira yekugadzira:
Nzira dzekugadzira zvinhu mumaindasitiri dzinosanganisira trichloroic phosphorus ne phosphoric acid munyu. Nzira ye hydrolysis inowedzera mvura zvishoma nezvishoma mu hydrolysis reaction pasi pekusanganiswa kwe trichloride kuti igadzire sub-phosphoric acid. Mushure mekunatswa, ChemicalBook inotonhora, crystallization uye discolor zvinogadzirwa, uye chigadzirwa chapera chinogadzirwa. PCI3+3H2O → H3PO3+3HCL yayo inogadzira hydrogen chloride recycling panguva yekugadzira, iyo inogona kugadzirwa kuita hydrochloric acid.
Kuchengetedzwa:
Zvinhu zvinogona kukonzera kutsva: muburi reH chinhu chinobvira; Kupisa kunoparadza utsi hune chepfu hwephosphorus oxide.
Hunhu hwekuchengetedza nekufambisa: kupinza mhepo mudura, tembiricha yakaderera; Chengeta zvakasiyana neH pore-releasing agent uye alkali.
Kurongedza: 25kg/Bhegi
Kuchengetedza: Chengeta munzvimbo yakavharwa zvakanaka, isingatsvedzeri chiedza, uye dzivirira kubva kuhunyoro.
