تناول هذا البحث دراسة عملية تكوين أيزومرات الهكسان الطبيعي باستخدام ثلاثي أوكسيد الموليبدينوم المدعوم بثاني أوكسيد التيتانيوم كمحفز. واستكشفت الدراسة تأثير محتوى أوكسيد الموليبدينوم وسرعة السائل في الفراغ ودرجة حرارة التفاعل. احتوى المحفز على 20.46% من ثلاثي أكسيد الموليبدينوم، مع قيم سرعة فراغية تتراوح من 0.5 إلى 2 ساعة-1 ودرجات حرارة تتراوح بين 200 درجة مئوية و275 درجة مئوية. وكان الهدف الرئيسي هو الاستفادة من هذا المحفز وتحليل حركية تفاعل تكوين أيزومرات الهكسان الطبيعي. وهدف البحث إلى تحديد الظروف المثلى للتفاعل، وتحديدًا درجة الحرارة، والسرعة الفراغية، لزيادة تحويل الهكسان الطبيعي إلى أيزومرات. وأشارت النتائج إلى أن أعلى تحويل، 53.21%، حدث عند سرعة السائل في الفراغ بالساعة 0.5 ساعة⁻¹ ودرجة حرارة 275 درجة مئوية. وقد اتبع التفاعل حركية من الدرجة الأولى مع طاقة تنشيط مقدارها 25.753 كيلوجول/مول.
