I-Etidronic Acid/ HEDP/CAS：2809-21-4
Incazelo emfushane:
Igama lomkhiqizo: I-Etidronic Acid
I-CAS: 2809-21-4
I-MF: C2H8O7P2
I-MW: 206.03
ISAKHIWO:
Ubuningi: 1.45 (60% aq.)
Iphuzu le-Flash: 198~199℃
Umkhiqizo omsulwa uyikristalu elimhlophe. Umkhiqizo wezimboni awunambala noma uphuzi okhanyayo ocwebezelayo. Uncibilika kalula emanzini futhi uncibilika ku-methanol kanye ne-ethanol. I-Hydroxyethylidene diphosphonic acid iyinto eluhlaza yamakhemikhali futhi ivame ukusetshenziswa ekuhlanzeni amanzi ezimbonini, emikhiqizweni yokuhlanza yasekhaya kanye nemikhiqizo yokunakekela umuntu siqu.

Ukusetshenziswa
Lo mkhiqizo uyinto eluhlaza eyinhloko yokwenza i-electroplating engena-cyanide. Uma yenziwe ibe yisisombululo se-electroplating yethusi esingenayo i-cyanide, inamandla amahle okubopha lapho i-electroplating ngqo ungqimba lwethusi ku-sodium iron. Isembozo sibushelelezi futhi sikhanya kahle. Ngokuvamile, umthamo womkhiqizo onokuqukethwe okungu-60% ngu-100 - 120 ml/L. Umthamo we-copper sulfate ungu-15 - 20 g/L. Ngaphezu kwalokho, ngaphambi kokufaka i-electroplating, cwilisa izingxenye ze-plating kusisombululo esingu-1% - 2% salo mkhiqizo ukuze wenze izingxenye ze-plating zibe yisimo esisebenzayo. Ukufaka i-electroplating ngemuva kwalesi sinyathelo kungathuthukisa umphumela. I-Hydroxyethylidene diphosphonic acid (HEDP) uhlobo olusha lwe-electroplating complexing agent engena-chlorine. Isetshenziswa njenge-ejenti eyinhloko yokuzinzisa ikhwalithi yamanzi ohlelweni lwamanzi okupholisa olujikelezayo, idlala indima yokuvimbela ukugqwala kanye nokuvimbela isikali. Lo mkhiqizo ungenye ye-organic polyphosphonic acid treatment water treatment. Kukhona nezinye izinhlobo zalolu hlobo lwemikhiqizo ekhiqizwa eShayina, njenge-amino trimethylene phosphonic acid (ATMP): [CH2PO(OH)2]3N, kanye ne-ethylenediamine tetra(methylene phosphonic acid) (EDTMP), njll. Ama-polyphosphonic acid e-organic athuthukiswa ngasekupheleni kwawo-1960 futhi aqashelwa cishe ngawo-1970. Ukuvela kwalolu hlobo lwe-ejenti yokwelapha amanzi kuye kwathuthukiswa ubuchwepheshe bokwelapha amanzi ngesinyathelo esikhulu. Uma kuqhathaniswa nama-polyphosphate angaphili, ama-polyphosphonic acid e-organic anokuqina okuhle kwamakhemikhali, akulula ukuwasebenzisa, angamelana namazinga okushisa aphezulu, adinga umthamo omncane we-ejenti, futhi anezimpawu zokugqwala kanye nokuvinjelwa kwesikali. Aluhlobo lwe-cathodic corrosion inhibitors kanye nohlobo lwe-non-stoichiometric scale inhibitors. Uma zisetshenziswa zihlanganiswe nezinye i-ejenti yokwelapha amanzi, zibonisa umphumela omuhle wokubambisana. Zinekhono elihle kakhulu lokugaya ama-ion amaningi ensimbi njenge-calcium, i-magnesium, ithusi, ne-zinc. Zize zibe nomthelela omuhle wokuvala ukusebenza kusawoti wezinto ezingaphili zalezi zinsimbi, njenge-CaSO4, i-CaCO3, i-MgSiO3, njll. Ngakho-ke, zisetshenziswa kabanzi kubuchwepheshe bokwelapha amanzi. Ama-reagent e-phosphorylating asetshenziselwa i-serine evikelwe kanye ne-pyranose.
Ukupakisha Nokuthumela
