چکیده
This study specifically examines the process of producing and analyzing biodiesel made from castor oil using base-catalyzed transesterification. The catalyst used in this process is potassium hydroxide (KOH), and the methanol (CH₃OH) used has a purity of ۹۹.۹%. The biodiesel obtained was analyzed extensively to assess its quality. The characterization techniques employed were Gas Chromatography (GC) for compositional analysis, Flash Point measurement for safety assessment, Kinematic Viscosity evaluation for flow properties, and Density determination for mass-volume relationships. To perform a statistical analysis, the Response Surface Method (RSM) was employed to determine the optimal conditions that would yield the highest rate of biodiesel production among the potential solutions. This study focused on three key variables affecting the transesterification process: ultrasonic duty cycle (using a ۲۴ kHz ultrasonic method varying the duty cycle from ۲۰% to ۱۰۰%), ultrasonic amplitude (varying from ۲۰% to ۱۰۰%), and reaction time (spanning from ۱۰ to ۱۵ minutes). This investigation achieved a biodiesel yield of ۸۸.۳۸% using a ۶۰% ultrasonic amplitude, a single ultrasonic cycle, and a ۱۵-minute reaction time. The regression model developed can be used to predict biodiesel's percentage conversion.کلیدواژه ها

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.
