Potassium thiocyanate - walax sun loo isticmaalo kiimikada gorfaynta

thiocyanate potassium (in IUPAC waydaarsanayeen casriga ah - thiocyanate potassium) - kiristaalo aan midab iyo ur; oo dhar cadcad xidhan wareegi jar kala qaybsan. walax waxa uu leeyahay pungent a dhadhan qadhaadh, waa sun. thiocyanate potassium waa heer sare L. in qase badan, sida biyaha, ethanol, iyo khamriga amyl.

soo dhaweynta

Xarunta ayaa la diyaariyey oo keliya macnaha kiimikada, waxaa kala oo laga helay ilo dabiici ah (dhiig iyo dhareerka dadka) - waa mid aad u qaali ah. Si aad u synthesize thiocyanate potassium ah, lagama maarmaan ah in ay isku daraan xal of thiocyanate ammonium iyo hydroxide potassium (magaca caadi ah - hydroxide potassium).

Tijaabada waxaa fuliyey daboosho ah, maxaa yeelay, ammonia ku keeni kartaa gubasho kiimikada iyo sumow; markaas sifeynta ee xalka la Daahiriyey waxaa la uumibixiyey iyo intii ka hadhay in la siiyo kiristaalo oo ah walaxda la doonayo. Marka alaabta wax soo saarka si ay u toddobaatan boqolkiiba oo ku filan thiocyanate ammonium muunad saafi ah, habkan waa mid aad wax ku ool ah.

Hab kale waa baaruud alloyed la cyanide potassium, laakiin habka a diyaarinta thiocyanate potassium sida waa arrin khatar ah, sababtoo ah sumoobo sare ee cyanide.

codsiga

thiocyanate Khusayso potassium, taagayo, iyo xal uruureen kala duwan oo ah qaybaha yar. Tusaale ahaan:

• warshadaha dharka.
• film sawir.
• Avv Organic.
• chemistry Analytical.

Meelaha isticmaalka

1. In warshadaha dharka ee. xal thiocyanate potassium waxaa loo isticmaalaa anmbarka unugyada, tus - Xariir, inta lagu guda jiro codsiga iyo taabato si loo ilaaliyo hantida bilowga ah waxyaabaha la.
2. In Avv organic. From potassium thiocyanate dhexsameeysmo jirka qaar ka mid ah walxaha organic, sida thiourea, oo saliid ah iniin khardal dardaro iyo formaldehyde kala duwan. Sidoo kale helaa iyadoo la kaashanayo thiocyanates kale, tus - copper thiocyanate-2.
3. In kimistari gorfaynta, xal thiocyanate potassium waxaa loo isticmaalaa go'aan ka soo baxay siifilisku bir ah trivalent in waxyaabaha la. Tusaale darey waa falcelinta, kaas oo ku lug leedahay thiocyanate potassium iyo chloride-3, sidoo kale loo yaqaan "dhiigga oo biyo ah", ferric at kaas oo purplish-cas potassium hexacyanoferrate a 3; Magaca caadiga ah - cusbo dhiigga cas. Thiocyanates sidoo kale loo isticmaalaa kala Biraha dhif ah sida thorium iyo lanthanum. Thiocyanate, chloride potassium iyo jelly waayadan dambe ka caawisaa in wax soo saarka ee dhiig aan dabiici ahayn waayo kinosomok, laakiin habkan dhaco waddada dhankeeda yiil, ay sabab u tahay hordhaca ah ee wax soo saarka film ee naqshadeynta kombiyuutarka.
4. In beeraha, ka xal ka heli Thiocyanates cayayaanka xoog leh. Waxaa jira laba reactions suurto gal ah:

• First - qaata thiocyano gaaska by tirka cusbo potassium, Dedaanna way waa gaas aad khatar u ah noolaha oo dhan iyo waxa dhif ah loo isticmaalo.
• Second - diridda thiocyanate potassium, lacag sii daayay inta lagu guda jiro hydrolysis acid tsianovodorodnoy iyo qayilo oo ah walaxda keentay in cyanogen. Cyan - oo aan ka yarayn sun ah, laakiin gaaska more culus la Dedaanna way la barbar dhigo, oo sidaas daraaddeed inta badan waxaa loo isticmaalaa sida cayayaanka ah.

thiocyanate potassium waa walax sun qiyaasta halis ah wuxuu ku saabsan yahay 0.9 grams oo ah walaxda halkii kiilo ee miisaanka jidhka ku saabsan diyaarinta afka ee xarunta.

helitaanka

thiocyanate potassium waa la iibsan karaa at kasta oo kiimiko dukaan, laakiin tiro yar, sababtoo ah sumoobo halkii sare. celceliska qiimaha reagent a - afar rubles halkii kiilo, iibinta inta badan ku koobnayn labada pounds halkii qof.

ammaanka

Sababtoo ah halka ay sumoobo, thiocyanate potassium waa in lagu keydiyo ee xaaladaha gaarka ah si waafaqsan xeerarka badbaadada ee loogu talagalay qabashada walxaha sunta ah:

1. Kiristaalo iyo xal of thiocyanate potassium mamnuuc daama iyo ingress heer sare ah loo baahnayn ee xal la uruuray sare oo ah walaxda aasaasiga ah maqaarka.
2. In kasta oo xaqiiqda ah in daroogada waa sun oo kaliya marka la dalbanayo shaqo uurkooda la maalkiisu waa la jecel yahay in jaakad caag shaybaarka gacmo gashi, iyo, sida dhammaan kiimikooyinka on shuruudaha ammaanka aasaasiga ah.
3. Waxaa lagama maarmaan ah in carruurta iyo dadka aadan aqoon farsamo haysan jaraan wax sida ay keeni kartaa dhacdooyinka xun khasaara ah ee reagents, si xun u isticmaalka, iyo geeri lama filaan ah.
4. walax ku safrayaan, oo ku filan deggan hawada Tan iyo markii, waxaa suurtagal ah si ay u maareeyaan walax kaydinta mugdi ah. armaajo qalalan. Iska ilaali huurka badan oo qorraxdu si toos ah, sida ku dhici karaa sabab u tahay sii daraysa ee kala daatay reagent ee qaybo ka qayb ay ku. Sidoo kale caadiga ah NFPA 704 calaamadeynta orthorhombic leeyahay calaamadaha soo socda: 3 0 0 W, kuna waari dhexdeeda 3 (lozenge buluug ah) - sumoobo, 0, (waayo, casaanka iyo jaalaha) - ololi iyo falcelin, iyo W - sumaddii for dhexgalka biyaha, kaas oo la sii daayay sun thiocyanic acid.

Xusa, tijaabo kiimikada - waxaa la yaab leh oo u gaar ah, laakiin marnaba ma dayaca tallaabooyinka nabadgelyo!
