Njira Yopangira

Njira zopangira mafakitale zimaphatikizapo phosphorous trichloride hydrolysis ndi njira ya phosphite.
Njira ya hydrolysis imawonjezera pang'onopang'ono madzi ku phosphorous trichloride pansi pa kugwedezeka kwa hydrolysis reaction kuti apange phosphorous acid, yomwe imayeretsedwa Chemicalbook, itakhazikika ndi crystallized, ndi decolorized kuti ipeze phosphorous acid yomalizidwa.
Njira yake yopangira PCI3+3H2O→H3PO3+3HCl imapanga haidrojeni chloride yobwezeretsanso, yomwe ingapangidwe kukhala hydrochloric acid.

Kukhazikika Kugwirizana

1. Imatulutsidwa pang'onopang'ono kukhala orthophosphoric acid mumlengalenga ndikuwola kukhala orthophosphoric acid ndi phosphine (poizoni kwambiri) ikatenthedwa mpaka 180 ℃.Phosphorous acid ndi dibasic acid, acidity yake ndi yamphamvu pang'ono kuposa phosphoric acid, ndipo imakhala ndi reducibility yamphamvu, yomwe imatha kuchepetsa Ag ion kukhala siliva wachitsulo ndi sulfuric acid kukhala sulfure dioxide.Wamphamvu hygroscopicity ndi deliquescence, zowononga.Zingayambitse kuyaka.Zokhumudwitsa pakhungu.Ikayikidwa mumlengalenga, imadya ndipo imasungunuka mosavuta m'madzi.Kutentha kukakhala kopitilira 160 ℃, H3PO4 ndi PH3 amapangidwa.
2.Kukhazikika: kukhazikika
3. Kusakaniza koletsedwa: alkali wamphamvu
4. Pewani kukhudzana: mpweya wotentha, wonyowa
5. Chiwopsezo chophatikizira: palibe kuphatikiza
6. Kuwonongeka kwa mankhwala: phosphorous oxide

Ntchito

1.Ndizopangira zopangira pulasitiki zokhazikika, ndipo zimagwiritsidwanso ntchito popanga ulusi wopangidwa ndi phosphite.
2.Itha kugwiritsidwa ntchito ngati yapakatikati ya glyphosate ndi ethephon, ndipo ingagwiritsidwenso ntchito popanga wothandizila kwambiri wamadzimadzi.

Zina Zowonjezera

1.Properties: kristalo woyera kapena wowala wachikasu, ndi kukoma kwa adyo komanso zosavuta zosavuta.
2. Malo osungunuka (℃): 73 ~ 73.8
3.Powira (℃): 200 (kuwola)
4.Kuchulukana kwachibale (madzi = 1): 1.65
5.Octanol/gawo logawa madzi: 1.15
6. Kusungunuka: Kusungunuka m'madzi ndi Mowa.
