Metal sabunlarının parafinin katalitik oksidasyonu üzerine etkisi
Bu
çalışmada; Ba, Mn ve Pb metal sabunları,
stearik asit ve bu metallerin tuzları kullanılarak sentezlenmiş ve erime
noktaları tayin edilmiştir. Sentezlenen metal sabunları farklı konsantrasyonlar
da parafin oksidasyonunda katalizör olarak kullanılmıştır. Oksidasyon sonucu
oluşan aldehit, keton ve karboksilli asitlerin miktarı, titrasyon
yöntemi kullanılarak asit değeri (AV.) olarak tayin edilmiştir. Bu değerler %
stearik asit değerine (%SAD) dönüştürülmüştür. Sonuç da Ba, Mn ve Pb stearat
sabunlarını, katalizör olarak Parafin oksidasyonu üzerindeki davranışları ve erime noktaları ile olan
ilişkisi incelenmiştir.
The catalyst effect of metal soaps on paraffin oxidation
In
this study; Ba, Mn and Pb metal soaps were synthesized using stearic acid with
the salts of these metals, and then melting points were determined. Different
concentrations of synthesized metal soaps were also used as catalysts for
paraffin oxidation. The amount of aldehyde, ketone and carboxylic acids formed
as a result of oxidation was determined as an acid value (A.V.) using the
titration method. These values were converted to% stearic acid value (%SAD).
The result also examines the relationship between Ba, Mn and Pb stearate soaps,
behavior on paraffin oxidation as a catalyst and melting points.
