Environmental benefits like biodegradability, natural, renewable source of energy, safely storage, better emissions etc is making Biodiesel more interesting for all the researchers in present scenario. </span><span style=\"font-size: 14.0pt; font-family: \'Times New Roman\',\'serif\'; mso-fareast-font-family: Calibri;\">Since India is deficient in edible oils, therefore, the non-edible oil like Karanjia, Jatropha, etc. could be the desirable source for India for production of bio-diesel. In Indian perspective most of the large scale production of biodiesel have been carried out by IOC. But so far in Western Rajasthan no such unit has been developed</span><span style=\"font-size: 14.0pt; font-family: \'Times New Roman\',\'serif\';\">. </span><span style=\"font-size: 14.0pt; font-family: \'Times New Roman\',\'serif\'; mso-fareast-font-family: Calibri;\">A lot of research available on the issues and problems related with fuel resources. Most of the time, the origins of these problems could be traced to the oil&rsquo;s high viscosity, low volatility, and reactivity due to unsaturated double bonds. These problems were more pronounced in direct-injection engines compared to precombustion (indirect injection) engines .The most common observation was that of injector coking, which eventually led to improper fuel atomization and decrease in combustion efficiency. </span></p>

Lot of waste industrial oil is obtained everyday. In the present research a method has been developed for the preparation of </span><span style=\"font-size: 14.0pt; font-family: \'Times New Roman\',\'serif\'; mso-fareast-font-family: Calibri;\">&nbsp;biodiesel </span><span style=\"font-size: 14.0pt; font-family: \'Times New Roman\',\'serif\';\">&nbsp;</span><span style=\"font-size: 14.0pt; font-family: \'Times New Roman\',\'serif\'; mso-fareast-font-family: Calibri;\">using the principles of Green chemistry from this waste industrial oil.&nbsp; Biodiesel is defined as the monoalkyl ester of long chain fatty acid derived from a renewable feedstock. Characteristic properties of biodiesel such as kinematic viscosity, cetane number, heating value, cloud point, density, pour point and flash point have been determined. Parameters with respect to different blends have also been determined. It has been observed that at 15 to 20 % blend better results are obtained.&nbsp;&nbsp; </span></p>
