乙二胺四甲叉膦酸五鈉

乙二胺四甲叉膦酸五鈉EDTMP.Na5CAS No.7651—99—2英文名稱：EthyleneDiamineTetra（MethylenePhosphonicAcid）PentasodiumSalt（EDTMP?Na5）CAS No.7651—99—2分UCH2一』一ONa/IONaCH2一N\ONaCH2—P——OH相對(duì)分子質(zhì)量：546.13 別名：乙二胺四亞甲基膦酸鈉、亞乙基二胺四甲叉膦酸鈉一、 性能與用途EDTMP?Na是中性產(chǎn)品，EDTMP?Na是含氮有機(jī)多元膦酸鹽，屬陰極型緩蝕劑。能與水混溶，無5 5毒無污染，化學(xué)穩(wěn)定性及耐溫性好，在200°C下仍有良好的阻垢效果。在水溶液中能離解成8個(gè)正負(fù)離子，因而可以與多個(gè)金屬離子螯合，形成多個(gè)單體結(jié)構(gòu)大分子網(wǎng)狀絡(luò)合物，松散地分散于水中，使鈣垢正常結(jié)晶破壞。EDTMP鈉鹽對(duì)硫酸鈣、硫酸鋇垢的阻垢效果好。EDTMP?Na用于循環(huán)水和鍋爐水的緩蝕阻垢劑、無氰電鍍的絡(luò)合劑、印染工業(yè)軟水劑、電廠冷卻5水處理等。EDTMP?Na的固體產(chǎn)品具有輕微吸潮性，方便運(yùn)輸和在寒冷條件下使用。5二、 技術(shù)指標(biāo)項(xiàng)目指標(biāo)外觀琥珀色透明液體白色粉末固體活性組分（以EDTMP?Na一計(jì)）%30.0-32.6三81.4活性組份（以 計(jì)）％24.0-26.0三65.0氯化物（以Cl-計(jì)）% W2.02.0密度（20C）g/cm3 三1.25—Fe（以Fe2+）含量mg/LW2020pH（原液）6.0-8.0（原液）6.0?8.0（1%水溶液）三、包裝與貯存:

EDTMP?Na液體用塑料桶包裝，每桶25kg或250kg,EDTMP?Na固體用內(nèi)襯聚乙烯袋的塑料袋包5 5裝，每袋凈重20Kg或根據(jù)用戶需要確定。貯于室內(nèi)陰涼、干燥處，防潮。固體貯存期為十個(gè)月，液體貯存期為十二個(gè)月。四、安全防護(hù)：EDTMLNas為中性，操作時(shí)注意勞動(dòng)保護(hù)，應(yīng)避免與皮膚、眼睛等接觸，接觸后用大量清水沖洗。PentasodiumSaltOfEthyleneDiamineTetra(MethylenePhosponicPentasodiumSaltOfAcid)(EDTMP?Na5)CAS:7651-99-2HO——]ONaONaN——CH-.——CHONaHOOONaCHCHHO——]ONaONaN——CH-.——CHONaHOOONaCHCH2—P——QHMolecularFormula:C6H15O12N2P4Na56 15 12 2 4 5MolecularWeight:546.131,Properties:EDTMPNa5isaneutralproduct,EDTMPNa5isamulti-nitrogen-containingorganicphosphates,acathodictypeinhibitor.Itismisciblewithwater,innocuousandnonepollutiontoenvironment,hasgoodchemicalstabilityandtemperaturetolerance.Itshowsexcellentscaleinhibitionabilityundertemperature200oC.Itcandissociateinto8positive-negativeions,thuscanchelatewithmanymetalionstoformpolymerreticulationcomplex,todestroythenormalcrystallizationofcalciumscale.EDTMP.Na5showsbetterantiscaleeffectstocalciumsulfateandbarium.EDTMP?Na5isusedforcirculatingwaterandboilerwaterscaleandcorrosioninhibitor,non-cyanideelectroplatingofcomplexingagent,softeningagentindyeingindustry,powerplantcoolingwatertreatment.SolidproductsofEDTMP.Na5haveslightlymoistureabsorption,areconvenientfortransportationandusingincoldconditions.2,Specification:AppearanceAmbertransparentliquidWhitepowdersolidActivecomponent(asEDTMPNa5)%30.0-32.6>81.4Activecomponent(asEDTMPA)%24.0-26.0>65.0Chloride(asCl-)%<2.02.0Density(20oC)g/cm3>1.25-Fe(asFe2+)contentmg/L<20.020.0pH(1%solution)6.0--8.06.0--8.0ItemsIndex3,Applicationrange&usingmethod:EDTMPScanbeusedascorrosioninhibitorincirculatingcoolwatersystemandboilerwater.Itisachelatingagentinnon-cyanogenelectroplatingindustryandawater-softeningagentinprinting&dyeingindustry.Whenusedalone,2~10mg/Lispreferred.WhenbuiltwithHPMAbyratioETDMP:HPMA=1:3,itcanbeusedforlowpressureboiler.ItcanalsobebuiltwithBTA,PAASandzincsalt.Organicphosphonicacid4,PackageandStorage:EDTMP.Na5liquid:Normallyin25kgor250kgplasticdrum.EDTMP.Na5Solid:innerlinerpolyethylene(PE)bag,outerplasticwovenbag,orconfirmedbyclients.Storageinroomshadyanddryplace.Storageperiodofsolidistenmo
