Kugadzira Nzira
Nzira dzekugadzira maindasitiri dzinosanganisira phosphorus trichloride hydrolysis uye phosphite nzira.
Iyo hydrolysis nzira zvishoma nezvishoma inowedzera mvura inodonha kune phosphorus trichloride pasi pekukurudzira kuti hydrolysis reaction ibudise phosphorous acid, iyo inonatswa Chemicalbook, yakatonhodzwa uye yakanatswa, uye decolorized kuti iwane yapera phosphorus acid.
Yayo PCI3+3H2O→H3PO3+3HCl yekugadzira nzira inoburitsa hydrogen chloride yekudzokorodza, inogona kugadzirwa kuita hydrochloric acid.
Kugadzikana Kwakabatana
1. Inogadziriswa zvishoma nezvishoma mu orthophosphoric acid mumhepo uye yakasvibiswa kuva orthophosphoric acid uye phosphine (yakanyanya chepfu) kana ichipisa kusvika ku180 ℃.Phosphorous asidhi idibasic asidhi, acidity yayo ine zvishoma kusimba kupfuura phosphoric asidhi, uye ine simba reducibility, iyo inogona kuderedza nyore Ag ions kune simbi sirivheri uye sulfuric acid kuita sulfur dioxide.Yakasimba hygroscopicity uye deliquescence, inoparadza.Inogona kukonzera kupisa.Kushungurudza kune ganda.Yakaiswa mumhepo, inodyisa uye inonyungudika zviri nyore mumvura.Kana tembiricha yakakwira kupfuura 160 ℃, H3PO4 uye PH3 inogadzirwa.
2.Kugadzikana: kugadzikana
3. Musanganiswa unorambidzwa: alkali yakasimba
4. Dzivisa mamiriro ekusangana: kupisa, mhepo yakanyorova
5. Aggregation ngozi: hapana aggregation
6. Kuora chigadzirwa: phosphorus oxide
Uses
1.Iyo chinhu chakasvibirira chekugadzirwa kwepurasitiki yakagadzikana, uye inoshandiswawo mukugadzirwa kwemashizha ekugadzira uye phosphite.
2.Inogona kushandiswa sepakati peglyphosate uye ethephon, uye inogonawo kushandiswa kugadzira yakakwirira-yepamusoro yemvura yekurapa mumiririri.
