Umkhiqizi Intengo Enhle I-Phosphorous Acid CAS:13598-36-2

Intengo Enhle Yomkhiqizi I-Phosphorous Acid CAS:13598-36-2 Isithombe Esivelele

incazelo emfushane:

I-phosphorus acid iyingxenye ebalulekile ekulungiseleleni amanye ama-compound e-phosphorus. I-phosphorus acid iyinto eluhlaza yokulungiselela ama-phosphonates okwelashwa kwamanzi njengokulawula insimbi ne-manganese, ukuvimbela nokususa isikali, ukulawula ukugqwala kanye nokuqinisa i-chlorine. Ama-alkali metal salts (ama-phosphites) e-phosphorus acid athengiswa kabanzi njenge-fungicide yezolimo (isb. i-Downy Mildew) noma njengomthombo ongcono wokudla okune-phosphorus ezitshalweni. I-phosphorus acid isetshenziswa ekuqiniseni izingxube zezinto zepulasitiki. I-phosphorus acid isetshenziselwa ukuvimbela izinga lokushisa eliphezulu lezindawo zensimbi ezivame ukugqwala kanye nokukhiqiza izinto zokugcoba kanye nezithasiselo zokugcoba.

Incazelo

I-phosphorus acid, i-H3PO3, iyi-diprotic (i-ionizing kalula ama-proton amabili), hhayi i-triprotic njengoba kungasikiselwa yile fomula. I-phosphorus acid iyingxenye ebalulekile ekulungiseleleni amanye ama-compound e-phosphorus. Ngoba ukulungiswa nokusetshenziswa kwe-“phosphorus acid” empeleni kuhlobene kakhulu ne-tautomer enkulu, i-phosphonic acid, ivame ukubizwa ngokuthi “i-phosphorus acid”. I-phosphorus acid inefomula yamakhemikhali i-H3PO3, evezwa kangcono njenge-HPO(OH)2 ukukhombisa uhlamvu lwayo lwe-diprotic.

Ukusetshenziswa kwe-Phosphorous Acid

1. I-phosphorus acid isetshenziselwa ukukhiqiza usawoti we-phosphate womanyolo njenge-potassium phosphite, i-ammonium phosphite kanye ne-calcium phosphite. Ihileleke kakhulu ekulungiseleleni ama-phosphite afana ne-aminotris (i-methylenephosphonic acid) (ATMP), i-1-hydroxyethane 1,1-diphosphonic acid (HEDP) kanye ne-2-phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), asetshenziswa ekwelapheni amanzi njengesikali noma isithiyo esibhubhisayo. Iphinde isetshenziswe ekuphenduleni kwamakhemikhali njenge-ejenti yokunciphisa. Usawoti wayo, i-lead phosphite isetshenziswa njenge-PVC stabilizer. Iphinde isetshenziswe njengesandulela ekulungiseleleni i-phosphine kanye nanjengesixhumi esiphakathi ekulungiseleleni amanye ama-compounds e-phosphorus.
2. I-phosphorus acid (H3PO3, orthophosphorous acid) ingasetshenziswa njengenye yezingxenye zokusabela zokwenziwa kwalokhu okulandelayo:
ama-α-aminomethylphosphonic acids nge-Mannich-Type Multicomponent Reaction
Ama-asidi angu-1-aminoalkanephosphonic nge-amidoalkylation alandelwe yi-hydrolysis
Ama-α-aminophosphonic acid avikelwe yi-N (ama-phospho-isosteres ama-amino acid emvelo) nge-amidoalkylation reaction
3. Ukusetshenziswa Kwezimboni: Lo mqoqi usanda kuthuthukiswa futhi usetshenziswe ngokuyinhloko njengomqoqi othize we-cassiterite kusuka kuma-ore anokwakheka okuyinkimbinkimbi kwe-gangue. Ngokusekelwe ku-phosphonic acid, u-Albright noWilson bathuthukise uhla lwabaqoqi ikakhulukazi ukuze kufakwe amaminerali e-oxidic (okungukuthi i-cassiterite, i-ilmenite kanye ne-pyrochlore). Kuncane kakhulu okwaziwayo ngokusebenza kwalaba baqoqi. Izifundo ezilinganiselwe ezenziwe ngama-ore e-cassiterite kanye ne-rutile zibonise ukuthi abanye balaba baqoqi bakhiqiza igwebu elikhulu kodwa babekhetha kakhulu.
