The dehydration reaction of ethanol to ether and ethylene was kinetically investigated in a flow system using •y-alumina. Pyridine was found to inhibit the formation of ethylene and ether. The rate of ethylene formation was investigated under steady state and non-steady state conditions and it was found to be zero order. The bimolecular ether formation is described by a first order equation of the Langmuir-Hinshelwood type. The activation energies for ethylene and ether formation were determined. A mechanism based on the participation of a common alkoxide intermediate for both reactions is proposed. تضمن البحث دراسة كيناتيكية نزع الماء من الايثانول وتكوين الاثير او الايثيلين باستخدام جاما - الومينا . واتضح من الدراسة ان البيريدين يقلل من تكوين الاثيلين في ظروف ثابتة وغير ثابتة ووجد انها تفاعلات من مرتبة الصفر . وتمت دراسة وتحديد طاقة التنشيط لتكوين كل من الاثير والاثيلين واتضح ان الميكانيكية تعتمد عل مشاركة الالكوكسيد كعامل وسيط للتفاعلين في حالة الاثير والاثيلين .
