Study on Rheological characteristics and Molecular Interaction properties of Annona Squamosa (Custard Apple) seed Biodiesel

摘要

The consequential use of the biodiesel as a provenience of renewable energy sustained a rapid growth over the past few years due to its substantial advantages like biodegradability, higher lubricity, low toxicity and less Carbon dioxide emissions. Conventionally, transesterification is used for the production of biodiesel by employing base catalysis. Here, this Biodiesel is prepped up from Annona Squamosa (Custard apple) seed oil, with methanol. The modus operands appropriates potassium hydroxide as a catalyst which is further tested in Compression Ignition (C.I.) engines. In the present endeavor, an attempt has been made to analyze the acoustical studies on various blend compositions of Biodiesel with conventional diesel in the ratios of 0%, 20%, 40%, 60%, 80% and 100% by determining relative viscosity, ultrasonic velocity, and density at 303K. From the data folioing the experiments, multifarious molecular interaction parameters like adiabatic compressibility, viscous relaxation time, inter molecular free length, specific acoustical impedance are calculated and the results are discussed in the light of solute-solvent interaction.
