TUNGSTOFOSFORİK ASİTLE MODİFİYE H-BETA ZEOLİT KATALİZÖRLER VARLIĞINDA DİFENİLMETAN SENTEZİ

Öz

Bu çalışmada, H-Beta (HB) zeolit destekli tungstofosforik asit (TPA) üzerinde benzenin benzil alkol ile reaksiyonundan difenilmetan (DPM) sentezi araştırılmıştır. Destek zeoliti üzerinde ağırlıkça %5 ila %20 arasında değişen TPA yüklemeleri ıslak emdirme yöntemi kullanılarak elde edilmiş ve desteklenen katalizörler kalsinasyon işlemine tabi tutulmuştur. Hazırlanan katalizörler ICP-OES, XRD, azot adsorpsiyon-desorpsiyon izotermleri, amonyağın sıcaklık programlı desorpsiyonu (NH3-TPD) ve FT-IR ile karakterize edilmiştir. Sonuçlar, %98,9 benzil alkol dönüşümü ve %87,3 difenilmetan seçiciliği ile %5TPA-HB'nin hazırlanan diğer katalizörlerden daha yüksek bir katalitik performansa sahip olduğunu göstermiştir. Çalışma, %5TPA-HB'nin uygun gözenek büyüklüğü ve yüksek erişilebilir güçlü asit bölgelerinin iyi bir kombinasyonu sayesinde DPM sentezinde potansiyel uygulamalara sahip olduğunu göstermiştir.
