Introduction: Catalytic reduction is widely used, important for industrial processes, and can be carried out on an enormous scale. An example of this is the catalytic cracking and reforming of crude oil to make gasoline. Other important reactions include, nitrobenzene being reduced catalytically to aniline and styrene being made by catalytic dehydrogenation of ethylbenzene. 1 In this lab, the catalytic hydrogenation of an unsaturated fat, glycerol trioleate (olive oil), to a saturated fat, glycerol tristearate, will be performed. This process will be done by using hydrogen gas with the catalytic metal, palladium on activated carbon. The product will be isolated and purified through the use of Pasteur pipet filtering. An IR analysis will be conducted to confirm the product. The mechanism for this reaction is shown below. Procedure and Data/Observations: The procedure for this experiment was taken from the “Catalytic Hydrogenation of Olive Oil.” 1 To begin, the apparatus was set up as shown in the figure. 1 It was important to make sure only a ½” magnetic stirring bar was put into the flask. A needle was pushed through the rubber septum and taken to the hydrogen tank. Once at the tank,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
