Metotia Gaosiga

O auala gaosi oloa e aofia ai le phosphorus trichloride hydrolysis ma le phosphite.
Ole auala ole hydrolysis e fa'aopoopo malie le vai ile phosphorus trichloride i lalo o le fa'aosoina mo le fa'afefeteina o le hydrolysis e fa'atupu ai le phosphorous acid, lea e fa'amamaina Chemicalbook, fa'amalieina ma tioata, ma decolorized ina ia maua mae'a phosphorous acid.
O lona PCI3 + 3H2O → H3PO3 + 3HCl gaosiga faʻagasologa e maua ai le hydrogen chloride mo le toe faʻaaogaina, lea e mafai ona faia i le hydrochloric acid.

Maumau Faatatau

1. O lo'o fa'ama'iina lemu i le orthophosphoric acid i le ea ma fa'apala i le orthophosphoric acid ma le phosphine (sili ona oona) pe a fa'avevela i le 180 ℃.Phosphorous acid o le dibasic acid, o lona acidity e sili atu le malosi nai lo le phosphoric acid, ma e malosi le faʻaitiitia, lea e faigofie ona faʻaitiitia ai Ag ions i metallic silver ma sulfuric acid i le sulfur dioxide.Malosi hygroscopicity ma deliquescence, pala.E mafai ona mu.Fa'aita i le pa'u.Tu'u i le ea, e suamalie ma faigofie ona solu ile vai.A maualuga le vevela nai lo le 160 ℃, H3PO4 ma PH3 e gaosia.
2.Stability: mautu
3. Faafefiloi faasaina: alkali malosi
4. Aloese mai tulaga faʻafesoʻotaʻi: vevela, ea susu
5. Tulaga lamatia: leai se tuufaatasiga
6. Mea fa'apalapala: phosphorus oxide

Fa'aoga

1.O se mea mataʻutia mo le gaosiga o faʻamautu palasitika, ma e faʻaaogaina foi i le gaosiga o filo faʻapipiʻi ma phosphite.
2.E mafai ona faʻaaogaina e avea o se vaeluagalemu o le glyphosate ma le ethephon, ma e mafai foi ona faʻaaogaina e maua ai le maualuga o le faʻaogaina o le vai.

Fa'amatalaga Faaopoopo

1.Properties: lanu paʻepaʻe poʻo le malamalama samasama tioata, faʻatasi ai ma le tofo garlic ma faigofie deliquescence.
2.Melting point (℃): 73 ~ 73.8
3. Fa'apuna (℃): 200 (decomposition)
4.Suavai tele (vai = 1): 1.65
