Pros
– Environmentally Friendly.
–
Biodiesel is a better lubricant than petroleum.
– Biodiesel gives fewer particulates when burnt.
– Biodiesel is easier to ignite than petroleum.

Cons
– Biodiesel is more expensive to produce.
–
If Biodiesel was used on a wider scale, more plants for oilwould be grown as a cash crop.
– Biodiesel gels at higher temperatures than petrodiesel.
–
Biodiesel degrades rubber hoses used on older engines.

• That is a Infrared Spectra of the starting oil.
• I used regular Canola oil.

• This is the Infrared Spectra of a mixture of
– Canola oil
– Methanol
– Potassium Carbonate (K2CO3)
• The band at 1160.52 cm-1 in the Canola oil NMRdisappeared. However bands 1196.18 and1169.98cm-1 appeared. That shows that there is aconversion of oil to methyl esters.
• A significant peak at 3318.88cm-1 shows there ismethanol in the solution.

• This is a infrared spectra of thefinished product
• I added household vinegar to themixture to neutralize the product andto extract any residue
• The OH peak has significantlydecreased because of the added acid

What’s a viscometer? – an instrument used to measure the
viscosity of a fluid.
– In general, either the fluid remainsstationary and an object moves through it,or the object is stationary and the fluidmoves past it. The drag caused by relativemotion of the fluid and a surface is ameasure of the viscosity.

How did I use theviscometer?
• I wanted to know how viscous biodiesel was atdifferent temperatures.
• So I ran a number of viscosity tests in a variety of water baths.
Push Here for a visual.

What is viscosity?
• In everyday terms (and for fluids only),viscosity is “thickness” or “internal friction”
•
For example, water is "thin", having a lowerviscosity, while honey is "thick", having ahigher viscosity.

Viscosity Calculations• Ethanol
o = 1.1212 p=0.789 g/ml A=? t= 99 secs (1min 39secs)η
o 1.1212=A(0.789)(99)
o A=0.0143539322
• Biodiesel(19oC)
o =? p=0.87402 A=0.014353922 t= 555sec (9min 15secs)η
o =(0.014353922)(0.87402 g/ml)(555sec)η
o =6.96282η
• Biodiesl(50oC)
o =? p=0.87402 A=0.014353922 t= 331sec (5min 31secs)η
o =(0.014353922)(0.87402g/ml)(331sec)η
o =4.1526η
• Biodiesel(0oC)
o =? p=0.87402 A=0.014353922 t= 1109η

Let me Explain…•
η is the viscosity in centipoises. The viscosity isalready given for Ethanol.
• p is the density of the tested liquid. That was alsoalready given for Ethanol
• t is the time for the liquid to flow past any crosssection (the left bulb)
• A is the constant for the viscometer.
