Markaad sahamiso adduunka kiimikooyinka, hal iskudhis oo u taagan kala duwanaanshaheeda iyo adeegsiga warshadaha oo dhan waatetraethyl silicate. In kasta oo qaacideeda kiimikaad ay u ekaan karto mid adag, haddana fahanku waa furaha qiimaynta sida xaruntani u dhaqaajiso falcelinta kiimikaad ee dhinacyo kala duwan, laga bilaabo elektiroonigga ilaa dawooyinka. Maqaalkan, waxaan ku burburin doonaaqaacidada tetraethyl silicateoo sahamin sida qaab-dhismeedkeeda kelliku u saameeyaa hab-dhaqankeeda codsiyada warshadaha.

Waa maxay Tetraethyl Silicate (TEOS)?

Tetraethyl silicate, oo badanaa loo yaqaanTEOS, waa iskudhis organosilicon lehqaacidada kiimikada Si(OC2H5)4. Xaruntani waxay ka kooban tahay aatom silicon (Si)ku xidhan afarkooxaha ethoxy (-OC2H5), ka dhigaysa amolecule tetrahedral. Marka hydrolyzed, TEOS foomamkasilica-Wax muhiim ah oo loo isticmaalo soo saarista qaybaha elektiroonigga ah, dahaarka, iyo codsiyada kale ee kala duwan.

Fahamkeedaformula kiimikaadwaxay noo ogolaanaysaa inaan qadarin sababtatetraethyl silicatewaa xarun qiimo leh oo ka kooban warshado badan.

Jebinta Formula Tetraethyl Silicate

Si loo fahmo muhiimadatetraethyl silicate (Si(OC2H5)4), aan marka hore baaro qaybaha gaarka ah ee ay ka kooban tahayqaab-dhismeedka molecular:

•Silikon Atom (Si):Atomka dhexe ee molecule, Silicon, wuxuu door muhiim ah ka ciyaaraa samaynta curaarta deggan ee ogsijiinta iyo atamka kaarboonka.

•Kooxaha Ethoxy (-OC2H5):Mid kasta oo ka mid ah afarta kooxood ee ethoxy wuxuu ka kooban yahay atamka ogsijiinta oo ku xidhan koox ethyl ah (C2H5). Tani waxay ka dhigaysaa TEOS mid aad u firfircoon oo awood u leh in lagu sameeyo falcelin kiimikaad oo muhiim ah sidahydrolysisiyouumiye.

Xirmooyinkani waxay siinayaan TEOS sifooyin gaar ah, taasoo ka dhigaysa mid aad waxtar u leh abuuristaalaabta silica ku salaysaniyo iskudhisyo kale oo horumarsan.

Sidee Qaaciidada Tetraethyl Silicate u Saamaynaysaa Falcelinta Kiimikada

Theqaacidada tetraethyl silicatewaxay lama huraan u tahay in la fahmo hab-dhaqankeeda fal-celinta kiimikada. Gaar ahaan, TEOS waxay martaa hab loo yaqaanhydrolysis, halkaas oo kooxaha ethoxy ay la falgalaan biyo, taasoo keentay in la sameeyosilicaiyo ethanol. Falcelintani waxay aasaas u tahay wax soo saarkafilimada khafiifka ah silicaiyo kuwo kalealaabta silikon ku salaysan, kuwaas oo muhiim u ah qalabka elektiroonigga ah, dahaarka, iyo daawooyinka.

Hydrolysis ee Tetraethyl Silicate

Marka TEOS ay ka falceliso biyaha, kooxaha ethoxy waxaa lagu beddelaa kooxaha hydroxyl, taasoo horseedaysa sameyntasilicon hydroxide(Si-OH). Habkani wuxuu dhalinayaaethanolsida wax soo saarka. Geedi socodka hydrolysis si heer sare ah loo xakameeyo goobaha warshadaha si loo hubiyo in samaynta tayo sare lehsilicaagabka.

Ka dib markii hydrolysis, eekooxaha hydroxylla sameeyay waxay la falgeli kartaa atomyada silikoon kale, taasoo horseedaysauumiyefalcelin. Talaabadani waxay samaysaasilikoon-oxygen-silicon(Si-O-Si) bonds, taasoo keentay abuurista qaab-dhismeedka shabakad loo yaqaansilica. Awoodda TEOS si ay u sameyso curaartan waxay u oggolaaneysaa inay gacan ka geysato sameyntaxoog badan, shabakadaha silica raagaya.

Codsiyada Tetraethyl Silicate iyo Foomkeeda Kiimikada

Theqaacidada tetraethyl silicateiyo falcelinteedu waxay ka dhigaysaa TEOS qayb muhiim ah dhowr warshadood:
