1.5.1 Flash Point
Flash point is the bottom temperature at which energy yields sufficient vapor to
cause blast prompting fire creation. Biodiesel has an upper flash point than arbitrary
diesel. Thus, it is a crucial protection standard for transportation and storing.
1.5.2 Viscosity
Kinematic viscosity is a physical property identified with the chain length and degree
of saturation. The viscosity of biodiesel is greater than fossil diesel; also, biodiesel
develops viscous or even hardened at low temperatures.
1.5.3 Cetane Number
The cetane number denotes the ignition feature of biodiesel in the engine. Normally,
biodiesel has a somewhat upper cetane number than fossil diesel. A low cetane
number results in a decline in combustion performance and greater gas release of
hydrocarbons. The cetane number can increase while raise length of fat acid chain
and ester groups.
1.5.4 Cloud Point
Cloud point denotes to the bottom temperature in which crystal construction in
biodiesel may be detected. The behavior of fuel at low temperatures is a chief
quality norm.
1.5.5 Oxidation Stability
Biodiesel fuels (especially with an extraordinary value of higher unsaturated esters)
are extra vulnerable to oxidative corruption than fossil diesel energy because the
methylene groups are vulnerable to radical attacks adjacent to the double bonds.
