چکیده

In this study, transesterification of sour cherry kernel oil was performed to produce microwave-based methyl ester. The effects of various factors affecting the reaction including microwave power (100-500 watts), molar ratio of alcohol to oil (3-15), catalyst concentration (0.3-1.5%) and reaction time (1 to 5 minutes) were investigated. Also, the physical and chemical properties of methyl esters including density, kinematic viscosity and refractive index were measured. Increasing the microwave power, catalyst concentration, alcohol to oil mole ratio, and reaction time to the optimal point increased the yield of methyl ester. The highest weight gain (92.03%), purity (82.21%) and final yield of methyl esters (81.41%) were obtained based on the following: at 4 min, the power of 300 watts, molar ratio of alcohol to oil 12 and 1.2% catalyst concentration.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
