Abstract
Bu çalışmada, sülfonik asit fonksiyonlu iyon değiştirici reçinenin, 5-12 karbonlu alkollerin, bor esterleriyle alkillendirilmesi incelenmiştir. Elde edilen sülfonat ester fonksiyonlu reçine, farklı zaman ve sıcaklık şartlarında fenollerin, aminlerin ve potasyum iyodür’ün alkillendirilmesinde kullanılmıştır. Deney sonuçları, polimerik alkil sülfonatların, yukarıda belirtilen bileşikleri dikkate değer verimlerle (%42-91) alkilleyebildiğini göstermiştir. Bu çalışmalara ilaveten, katı destekli sülfonat esterlerinin geri kazanılabilirlikleri de incelenmiştir. Bununla ilgili olarak yapılan denemeler üçüncü kez geri kazanılıp kullanılan bütil sülfonat fonksiyonlu reçinenin, alkilleme etkinliğinde pratikçe bir değişme olmadığını göstermiştir.
In this work, we have studied alkylation of acid functional ion exchange resin with boron esters derived from C5-C12 alcohols and the resulting sulfonate ester functional resin was employed for alkylation of phenols, amines and potassium iodide in various time temperature conditions. These investigations showed that, polymer supported sulfonate ester function gives alkylated derivatives of those substrates in reasonable yields (42-91%). Regenerability of the supported sulfonate esters was also studied. The relevant experiments revealed that, practically no activity lost was detected after three times of recycling of sulfonate functional resin in butylation of phenol.
