Tikanga Whakaputa

Ko nga tikanga whakaputa ahumahi ko te phosphorus trichloride hydrolysis me te tikanga phosphite.
Ko te tikanga hydrolysis te taapiri i te topata wai ki te ūkuikui trichloride i raro i te whakakorikori mo te tauhohenga o te waikura ki te whakaputa i te waikawa ūkuikui, he mea para ma Chemicalbook, ka whakamataohia, ka whakamaaramatia, ka whakakorehia te tae kia whiwhi waikawa ūkuikui kua oti.
Ko tana mahi hangahanga PCI3+3H2O→H3PO3+3HCl ka puta te hauwai hauwai mo te hangarua, ka taea te hanga hei waikawa maaota.

Pūmautanga e pā ana

1. Ka whakapourihia ki te waikawa orthophosphoric i te rangi, ka pirau ki te waikawa orthophosphoric me te phosphine (tino paitini) ina wera ki te 180 ℃.Ko te waikawa Phosphorous he waikawa dibasic, he iti ake te kaha o tona waikawa i te waikawa phosphoric, a he kaha te whakaheke, ka ngawari te whakaheke i nga katote Ag ki te hiriwa whakarewa me te waikawa pungatara ki te sulfur dioxide.Ko te hygroscopicity kaha me te deliquescence, te pirau.Ka taea te weranga.Ka whakaparahako ki te kiri.Ka tuu ki te hau, ka maroke, ka ngawari ki te wairewa.Ina teitei ake te pāmahana i te 160 ℃, ka hangaia te H3PO4 me te PH3.
2.Stability: pumau
3. ranunga rāhuitia: kaha alkali
4. A ape i nga tikanga whakapiri: wera, hau makuku
5. Morearea whakahiato: kahore he whakahiato
6. Hua pirau: ūkuikui waikura

Whakamahinga

1.He rauemi mata mo te hanga i nga whakapumau kirihou, ka whakamahia ano hoki i roto i te hanga o nga muka waihanga me te phosphite.
2.Ka taea te whakamahi hei takawaenga o te glyphosate me te ethephon, ka taea hoki te whakamahi ki te whakaputa i te kaihoko maimoatanga wai tino pai.

Nga korero taapiri
