Phosphorous Acid, inorganic compound ine kemikari formula H3PO3.Iyo chena crystalline poda, nyore kunyungudika mumvura uye ethanol, uye zvishoma nezvishoma oxidized kupinda orthophosphate mumhepo.Phosphite idibasic asidhi, acidity yayo ine simba zvishoma pane phosphoric asidhi, ine yakasimba kuderedza pfuma, nyore kuderedza sirivheri ions (Ag +) kune sirivheri simbi (Ag), inogona kuderedza sulfuric acid kuita sulfur dioxide.Iyo ine yakasimba hygroscopicity uye deliviousness, uye inoora.Phosphite inonyanya kushandiswa seyekudzikisa mumiririri, naironi inopenya mumiriri, asi zvakare inoshandiswa se phosphite mbishi zvinhu, pesticide intermediates uye organic phosphorus mvura yekurapa vamiririri.
Properties:white crystalline powder.Soluble mumvura uye doro.Density: 1.651g/cm3, nzvimbo yekunyungudika: 73 ℃, nzvimbo yekubikira: 200 ℃.
APPLICATION:
1.Phosphorous acidinoshandiswa kugadzira fetireza phosphate munyu se potassium phosphite, ammonium phosphite uye calcium phosphite.Inobatanidzwa mukugadzirwa kwephosphites seaminotris (methylenephosphonic acid) (ATMP), 1-hydroxyethane 1,1-diphosphonic acid (HEDP) uye 2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), inowana. kushandiswa mukurapa kwemvura sechiyero kana corrosive inhibitor.Inoshandiswawo mukugadzirisa kwemakemikari sechinhu chinoderedza.Munyu wayo, lead phosphite inoshandiswa sePVC stabilizer.Inoshandiswawo sechinhu chinotangira mukugadzirira kwephosphine uye sepakati mukugadzirira kwemamwe phosphorus compounds.
2.Phosphorous acid(H3PO3, orthophosphorous acid) inogona kushandiswa seimwe yezvinoita zvikamu zvekubatanidza kwezvinotevera:
α-aminomethylphosphonic acids kuburikidza neMannich-Type Multicomponent Reaction
1-aminoalkanephosphonic acids kuburikidza neamidoalkylation inoteverwa nehydrolysis
N-yakachengetedzwa α-aminophosphonic acids (phospho-isosteres yemasikirwo amino acids) kuburikidza neamidoalkylation reaction.
3. Mashandisirwo eindasitiri:Muunganidzi uyu akagadzirwa nguva pfupi yadarika uye akashandiswa zvakanyanya semuunganidzi chaiwo wecassiterite kubva muore ine yakaoma gangue kuumbwa.Pahwaro hwephosphonic acid, Albright naWilson vakagadzira huwandu hwevaunganidzi kunyanya kutenderera kweoxidic minerals ( kureva cassiterite, ilmenite uye pyrochlore).Zvishoma kwazvo zvinozivikanwa nezvekuita kwevaunganidzi ava.Zvidzidzo zvishoma zvakaitwa necassiterite uye rutile ores zvakaratidza kuti vamwe vevaunganidzi ava vanoburitsa furo rinoputika asi vainyanya kusarudza.
Nzira yekugadzira:
Nzira dzekugadzira maindasitiri dzinosanganisira trichloroic phosphorus uye phosphoric acid munyu.Iyo hydrolysis nzira zvishoma nezvishoma inowedzera mvura kune hydrolysis reaction pasi pekusanganiswa kwe trichloride kugadzira sub-phosphoric acid.Mushure mekunatsa, inotonhora ChemicalBook, iyo crystallization uye discoloration inogadzirwa, uye chigadzirwa chakapedzwa chinogadzirwa.Yayo PCI3+3H2O → H3PO3+3HCL inogadzira hydrogen chloride recycling panguva yekugadzira, iyo inogona kugadzirwa muhydrochloric acid.
Chengetedzo:
Kupisa kwengozi maitiro: muH hole mumiririri anopisa;Kupisa kunoparadza utsi hwe phosphorus oxide.
Kuchengetedza uye zvekufambisa maitiro: warehouse ventilation yakaderera tembiricha yakaoma;Chengetedza zvakaparadzana kubva kuH pore-releasing agent uye alkali.
Kurongedza: 25kg / bhegi
Kuchengetera: Chengetedza mune yakavharwa zvakanaka, isingavheneki, uye chengetedza kubva pakunyorova.
