Özet
VII ÖZET Bazı bazik metaller (sodyum ve potasyum) ve geçiş metallerinden kobaltın naftenik asitler ile verdikleri naftenatlar, biyolojide, ziraatte, tıpta ve diğer alanlarda büyük öneme sahiptir. Buda anorganik sentezlerde naftenatlarm ve onun koordinasyon bileşiklerinin incelenmesine neden olmuştur. Burada halkaya sahip karbon asitlerinin kompleks meydana getirmesini ve bunların basit karboksilatlardan farkını belirlemek için çalışmalar yapıldı. Bununla ilgili olarak belli bir metotla naftenik asitler bisiklo(2,2,l)hept-5-en-2 karboksilik asit, salisilik asit, siklohekzan karboksilik asit, adipik asit ve doğal petrol asit) ile NaOH yada KOH'ın karşılıklı etkisiyle sodyum ve potasyum karboksilat elde edildi. Daha sonra subsutüsyon reaksiyonu ile kobalt naftenatlar sentezlendi. Kobalt naftenatın sentezinde kullanılan metotlar şunlardır. 1. İki basamaklı yer değiştirme reaksiyonu 2. Tek basamaklı reaksiyon 3. Kobalt naftenatlan elde ederken pH'a göre paylaşma sabiti ve ekstraksiyon yüzdesi ile değişimlerinin bulunması Kobalt karboksilatlarm optimal sentezi, tek basamaklı yer değiştirme reaksiyonu ile gerçekleşmiştir. Her üç reaksiyonda da pH 7 civarında verim birbirine yakın olmuştur. Bu metodlarla elde edilen naftenatlarm element analizleri, İR, NMR spektrumları ve kobalt naftenatlarm termogravimetrik analizi alınarak fiziksel, kimyasal özellikleri ve kristal yapısı incelenmiştir. Uygulama alanları araştırıldığında sodyum ve potasyum naftenatlarm fizyolojik ve biyolojik aktifliklerine bakılarak tıpta (antimikrobik madde) ve ziraatte kullanılabileceği yine kobalt naftenatın mikrogübre olarak ve süperfosfat gübresinin temizlenmesinde olarak kullanılabileceği ortaya çıkmıştır.
VIII SUMMARY Some alkali metals (sodium and potassium) and cobalt one of the transition metals are giving naphthenate compounds with naphthenic acids which are of big importance in the fields of biology, agriculture, medicine and in other fields as well. This effected the research of naphthenate and their coordination compounds inorganic synthesis seriously. So the experiments are made to make complex compounds for cyclic carbon acid and their differences from simple carboxylates. By using a method with the effect of naphthanic acids(2-bicyclo-[2.2.1]-hepten-2-oik acid, salicylic acid, cycloheksane carboxylic acid, adipic acid and natural naphthenic acid) and sodium hydroxide (or potassium hydroxide), sodium (or potassium) naphthenates are produced. Then with the reaction of substation, cobalt naphthenates are synthesized. For the cobalt naphthenates synthesis following methods were used. 1. Two steps substitution reactions. 2. One step reaction. 3. While the cobalt naphthenate was coming out sharing constant and extraction percentage values depending on pH were found. The optimal syntheses of cobalt naphthenates is occurred by a one step reaction. In all three reaction at the pH around 7 the yield was very close. The structural characteristics and the physical and chemical properties of the naphthenates obtained by this methods analyzed by IR, NMR and cobalt by termogravimetric analysis as well. When the application fields were searched, looking on physiological activities of sodium and potassium naphthenates they can be used in the fields of medicine (antimicrobial agent) and agriculture, while cobalt naphthenates can be used as a micro fertilizer and in the purification of superphosphate fertilizers.
