Indlela Yokukhiqiza

Izindlela zokukhiqiza zezimboni zihlanganisa i-phosphorus trichloride hydrolysis kanye nendlela ye-phosphite.
Indlela ye-hydrolysis yengeza kancane kancane amanzi adonsela phansi ku-phosphorus trichloride ngaphansi kokunyakaziswa kwe-hydrolysis reaction ukuze kukhiqizwe i-phosphorous acid, ecwengiwe i-Chemicalbook, epholile futhi efakwe amakristalu, futhi ikhishwe umbala ukuze kutholwe i-phosphorous acid ephelile.
Inqubo yayo yokukhiqiza ye-PCI3+3H2O→H3PO3+3HCl ikhiqiza i-hydrogen chloride ukuze igaywe kabusha, engenziwa ibe i-hydrochloric acid.

Ukuzinza Okuhlobene

1. I-oxid kancane kancane ibe yi-orthophosphoric acid emoyeni futhi ibole ibe yi-orthophosphoric acid ne-phosphine (inobuthi obuphezulu) uma ishisiswe ibe ngu-180℃.I-Phosphorous acid iyi-dibasic acid, i-asidi yayo inamandla kancane kune-phosphoric acid, futhi inokuncipha okuqinile, okunganciphisa kalula i-Ag ions ibe yisiliva yensimbi kanye ne-sulfuric acid ibe yi-sulfur dioxide.I-hygroscopicity enamandla kanye ne-deliquescence, i-corrosion.Ingabangela ukusha.Ukucasula esikhumbeni.Ibekwe emoyeni, iyadliwa futhi incibilika kalula emanzini.Uma izinga lokushisa lingaphezulu kuka-160℃, i-H3PO4 ne-PH3 ziyakhiqizwa.
2.Ukuzinza: uzinzile
3. Ingxube engavunyelwe: i-alkali enamandla
4. Gwema izimo zokuxhumana: umoya oshisayo, onomswakama
5. Ingozi yokuhlanganisa: akukho ukuhlanganisa
6. Umkhiqizo wokubola: i-phosphorus oxide

Isebenzisa

I-1.Iyimpahla engavuthiwe yokwakhiwa kweziqinisi zepulasitiki, futhi isetshenziswa nasekukhiqizeni imicu yokwenziwa kanye ne-phosphite.
I-2.Ingasetshenziswa njengendawo ephakathi ye-glyphosate ne-ethephon, futhi ingasetshenziswa ukukhiqiza i-ejenti yokwelashwa kwamanzi esebenza kahle kakhulu.

Ulwazi Olwengeziwe

1.Properties: ikristalu elimhlophe noma eliphuzi elikhanyayo, elinokunambitheka kukagalikhi kanye nokudliwa kalula.
2.Iphuzu elincibilikayo (℃): 73 ~ 73.8
3.Indawo yokubilisa (℃): 200 (ukubola)
4.Ukuminyana kwesihlobo (amanzi = 1): 1.65
5.I-Octanol/i-partition coefficient yamanzi: 1.15
6. Ukunyibilika: Incibilika emanzini ne-ethanol.

Okwedlule: I-N-methylcyclohexylamine
