Babban ingancin phosphorus (3)

Hanyar samarwa

Hanyoyin samar da masana'antu sun haɗa da sinadarin phosphorus trichloride hydrolysis da hanyar phosphite.
Hanyar hydrolysis sannu a hankali tana ƙara ruwa dropwise zuwa phosphorus trichloride a ƙarƙashin motsawa don amsawar hydrolysis don samar da acid phosphorous, wanda aka tace Chemicalbook, sanyaya da crystallized, kuma an canza launin don samun ƙarancin phosphorous acid.
Tsarinsa na PCI3+3H2O→H3PO3+3HCl yana samar da hydrogen chloride don sake amfani da shi, wanda za'a iya sanya shi ya zama hydrochloric acid.

Natsuwa mai alaƙa

1. Yana sannu a hankali oxidized zuwa orthophosphoric acid a cikin iska kuma bazu zuwa cikin orthophosphoric acid da phosphine (mai guba sosai) lokacin mai tsanani zuwa 180 ℃.Phosphorous acid shine dibasic acid, acidity nasa ya dan fi karfi fiye da phosphoric acid, kuma yana da karfi mai karfi, wanda zai iya rage Ag ions zuwa azurfa karfe da sulfuric acid zuwa sulfur dioxide.Strong hygroscopicity da deliquescence, lalata.Zai iya haifar da kuna.Haushi ga fata.Sanya shi a cikin iska, yana raguwa kuma yana da sauƙin narkewa cikin ruwa.Lokacin da zafin jiki ya fi 160 ℃, ana haifar da H3PO4 da PH3.
