I-Etidronic Acid/CAS:10192-30-0
Incazelo emfushane:
Igama lomkhiqizo: I-Etidronic Acid
Uhlobo:ZA-N
I-CAS:2809-21-4
MF:C2H8O7P2
I-MW: 206.03
ISAKHIWO:
Ubuningi: 1.45 (60% aq.)
iphuzu lokuncibilika: 198~199℃
Umkhiqizo omsulwa uvela njengamakristalu amhlophe, kanti uhlobo lwezimboni luwuketshezi olukhanyayo olungenambala kuya koluphuzi olukhanyayo. Luncibilika kalula emanzini, i-methanol kanye ne-ethanol. I-1-Hydroxyethane-1,1-diphosphonic acid iyinto eluhlaza yamakhemikhali, evame ukusetshenziswa ekuhlanzeni amanzi ezimbonini, emikhiqizweni yokuhlanza yasekhaya kanye nemikhiqizo yokunakekela umuntu siqu.

Ukusetshenziswa
Lo mkhiqizo uyinto eyinhloko yokwenza i-electroplating engena-cyanide. Uma yenziwe ibe yisisombululo se-electroplating sethusi esingenayo i-cyanide, ingabeka ngqo izendlalelo zethusi ezintweni ze-sodium-iron ngokunamathela okuhle kakhulu. Isembozo sinobuso obubushelelezi kanye nokukhanya okuhle kombala. Umthamo ojwayelekile wesisombululo sokuqukethwe okungu-60% ungama-100 kuya ku-120 ml ngelitha, kanti umthamo we-copper sulfate ungama-15 kuya ku-20 amagremu ngelitha. Ngaphezu kwalokho, ukucwilisa izingxenye ezifakwe ephepheni kusisombululo esingu-1% kuya ku-2% salo mkhiqizo ukuze kusebenze ubuso bazo ngaphambi kokufaka i-electroplating kungathuthukisa kakhulu umphumela we-electroplating.
I-Hydroxyethylidene Diphosphonic Acid (HEDP) uhlobo olusha lwe-electroplating complexing agent engena-chlorine. Isebenza njengesiqinisi esiyinhloko sekhwalithi yamanzi ezinhlelweni zamanzi okupholisa ezijikelezayo futhi isebenza ekuvimbeleni ukugqwala kanye nokuvimbela isikali. Ingenye ye-organic polyphosphonic acid treatment water agents. Kuneminye imikhiqizo ekhiqizwe ekhaya yalolu hlobo, njenge-Amino Trimethylene Phosphonic Acid (ATMP) enefomula \([CH_2PO(OH)_2]_3N\), i-Ethylene Diamine Tetra Methylene Phosphonic Acid (EDTMP), nokuningi.
Ama-polyphosphonic acid e-organic ayisigaba sezinto zokwelapha amanzi ezakhiwa ngasekupheleni kwawo-1960 futhi zaqashelwa cishe ngawo-1970. Ukuvela kwalezi zinto zokwelapha amanzi kuthuthuke kakhulu. Uma kuqhathaniswa nama-polyphosphate angaphili, ama-polyphosphonic acid e-organic anezici ezinhle kakhulu zokuqina kwamakhemikhali, ukumelana ne-hydrolysis, ukubekezelelana kwezinga lokushisa eliphezulu, umthamo ophansi, kanye nokusebenza okuhlanganisiwe kokugqwala kanye nokusebenza kokuvimbela isikali.
Zisebenza njengezithibi zokugqwala kwe-cathodic kanye nezithibi zesikali ezingezona eze-stoichiometric. Uma zihlanganiswa nezinye izinto zokwelapha amanzi, ziletha imiphumela emihle yokusebenzisana. Zibonisa amandla amahle kakhulu okuchela ama-ion amaningi ensimbi kufaka phakathi i-calcium, i-magnesium, ithusi kanye ne-zinc, futhi zinemiphumela emihle yokuvala ukusebenza kusawoti we-inorganic walezi zinsimbi njenge-calcium sulfate (\(CaSO_4\)), i-calcium carbonate (\(CaCO_3\)) kanye ne-magnesium silicate (\(MgSiO_3\)). Ngakho-ke, zisetshenziswa kabanzi kubuchwepheshe bokwelapha amanzi.
I-reagent ye-phosphorylation ye-serine evikelwe kanye ne-pyranose.
