In this work biodiesel is synthesized using low cost feedstock Cassia spectablis seed oil. The Cassia spectablis seeds yield 25% oil. Various physicochemical properties of seed oil have been determined according to AOCS methods. The Acid value of seed oil is 1.8 mg KOH/g oil and is directly subjected for single step base catalyzed transesterification process under optimized condition. The synthesized biodiesel is characterized using FT-IR, ¹H -NMR and ¹³C NMR spectroscopic methods for the confirmation of fatty acid methyl esters. The biodiesel is subject for GC-FID analysis to quantify its component fatty acids. Various fuel properties relevant to biodiesel are evaluated computationally and substantiated with experimental values. The fuel properties are comparable with the existing biodiesels like Soyabean, Sunflower, Rape seed oil biodiesel and petrodiesel which are further verified with biodiesel fuel standards as per ASTM D6751, BIS 1567 and EN 14,214 standards.

在这项工作中，使用低成本原料决明子 种子油合成生物柴油 。将 决明子spectablis 种子能产生25％的油。已经根据AOCS方法确定了种子油的各种理化性质。种子油的酸值为1.8 mg KOH / g油，可在最佳条件下直接进行单步碱催化的酯交换反应。使用FT-IR，¹ H - NMR和 ¹³表征合成的生物柴油 用13 C NMR光谱法确认脂肪酸甲酯。该生物柴油要进行GC-FID分析，以定量其组成脂肪酸。通过计算评估与生物柴油有关的各种燃料特性，并用实验值进行证实。燃料特性可与现有的生物柴油（如 大豆，向日葵， 油菜籽油生物柴油和石油柴油）相媲美，并已根据ASTM D6751，BIS 1567和EN 14,214标准通过生物柴油燃料标准进行了进一步验证。
