Hana Hana
ʻO nā ʻano hana hana ʻoihana e pili ana i ka phosphorus trichloride hydrolysis a me ke ʻano phosphite.
Hoʻohui mālie ke ʻano hydrolysis i ka wai dropwise i ka phosphorus trichloride ma lalo o ka hoʻoulu ʻana no ka hopena hydrolysis e hoʻohua i ka waikawa phosphorous, ka mea i hoʻomaʻemaʻe ʻia ʻo Chemicalbook, hoʻoluʻu a crystallized, a decolorized no ka loaʻa ʻana o ka waikawa phosphorous.
ʻO kāna kaʻina hana hana PCI3+3H2O→H3PO3+3HCl e hana i ka hydrogen chloride no ka hana hou ʻana, hiki ke hana ʻia i loko o ka waikawa hydrochloric.
Pili Pa'a
1. Hoʻoheheʻe ʻia ia i loko o ka orthophosphoric acid i ka lewa a decomposed i loko o ka orthophosphoric acid a me ka phosphine (ʻawaʻawa loa) ke hoʻomehana ʻia i 180 ℃.ʻO kaʻakika Phosphorous kahiʻakika dibasic, uaʻoi aku ka ikaika o konaʻakika ma mua o ka phosphoric acid, a he ikaika ka hoʻohaʻahaʻaʻana, hiki ke maʻalahi i ka hoʻohaʻahaʻa i nā iona Ag i ke kālā metala a me ka sulfuric acid i ka sulfur dioxide.ʻO ka hygroscopicity ikaika a me ka deliquescence, corrosive.Hiki ke kumu i ke kuni.Hoʻonanea i ka ʻili.Hoʻokomo ʻia i ka lewa, ʻoluʻolu a hiki ke hoʻoheheʻe ʻia i ka wai.Ke kiʻekiʻe ka mahana ma mua o 160 ℃, hana ʻia ka H3PO4 a me PH3.
2.Stability: kūpaʻa
3. Hoʻohui ʻia i pāpā ʻia: alkali ikaika
4. E pale i nā kūlana pili: ea wela, humid
5. ʻO ka pōʻino hui: ʻaʻohe hui
6. Decomposition huahana: phosphorus oxide
Hoʻohana
1. He mea maka no ka hana ʻana i nā stabilizer plastik, a hoʻohana ʻia hoʻi i ka hana ʻana i nā fiber synthetic a me ka phosphite.
2. Hiki ke hoʻohanaʻia ma keʻano he waena o ka glyphosate a me ka ethephon, a hiki ke hoʻohanaʻia no ka hanaʻana i ka mea hoʻomaʻamaʻa wai kiʻekiʻe.
ʻIke hou aku
