WARMUPWhat do you think about funding research for alternative sources of diesel?
Where should we start and how much time/ money should we put into it?
REMINDERQuiz next class
◦Study notes, homework, review sheet
What is Diesel?The primary oil used in motor
vehicles
What is biodiesel?Type of diesel developed from
vegetable oil!◦Can also be made from fats and
greases
BenefitsRenewable
Only takes crops a year to grow
Give off less pollution when burned
Reduction in land destruction
Safer to handle
Nontoxic
NegativesLower fuel efficiency
Does not do well in cold weather
Takes a lot of oil to produce necessary amount
Take more time to process and transport
CurrentlyBiodiesel is the fastest growing
alternative fuel source!!
What You Will Be Doing TodayMaking your own biodiesel!!!
LAB REPORTFollow rubric on my wiki!!!!!
Pick reliable individuals to work with.◦If you choose to do an entire lab
report on your own you need to let me know.
◦The lab report can also be turned in before the due date for me to edit
◦LAB REPORT DUE-> 04/26/2013
Lab QuestionsQuestions: 1. What changes did you see between the characteristics
of the starting materials (cooking oil, methanol, and potassium hydroxide solution) and the final products (biodiesel and glycerol)? What evidence is there that a chemical reaction has occurred?
3. What is the purpose of ‘washing’ the biodiesel mixture with salt water?
7. Is biodiesel really green? Explain at least two arguments in support of the idea that biodiesel is a “greener” fuel. Also present one argument that biodiesel is not a “greener” fuel. Reference your lab data when appropriate.
