Titration report

Procedure Filter WVO to remove any food scraps or solid particles. Heat WVO to remove any water content optional. Perform titration to determine how much catalyst is needed. Heat WVO, mix in the sodium methoxide while stirring.

Allow to settleremove the glycerine. This procedure is called transesterification, similar to saponification. Saponification is soap making. To make soap you take a transfatty acid or triglyceride oil or kitchen grease and blend it with a solution of sodium hydroxide NaOH, caustic soda or lye and water.

This reaction causes the ester chains to separate from the glycerine. These ester chains are what becomes the soap.

They're also called lipids. Their unique characteristic of being attracted to polar molecules such as water on one end and to non-polar molecules like oil on the other end is what makes them effective as soap.

When mixed in with the WVO Titration report strong polar-bonded chemical breaks the transfatty acid into glycerine and also ester chains biodieselalong with some soap if you're not careful more on that later.

The esters become methyl esters. They would be ethyl esters if reacted with booze ethanol instead of methanol. Figures show these two reactions. The zigzag lines in the triglyceride diagram Figure 1 are shorthand for carbon chains. At both ends of each line segment is a carbon atom. Figure 1 In Figures 2 and 3 these zigzags are shorthanded as R1, 2 and 3.

Figure 2 Figure 3 1. Filtering Filter the WVO to remove food particles. You may have to warm it up a bit first to get it to run freely, 95 deg F 35 deg C should be enough. Use a double layer of cheesecloth in a funnel, or a restaurant or canteen-type coffee filter.

STARTING DOSE

Removing the water Many people heat the WVO first to remove any water content. Waste oil will probably contain water, which can slow down the reaction and cause saponification soap formation. The less water in the WVO the better. Mike and Joe, an organic farmer who makes 40 gallons of biodiesel a week for the farm truck and tractor.

This is how they do it. Raise the temperature to deg F deg Chold it there and allow any water to boil off. Use the mixer to avoid steam pockets forming below the oil and exploding, splashing hot oil out of the container.

Or drain water puddles out from the bottom as they form -- you can save any oil that comes out with the water later. When boiling slows, raise the temperature to deg F deg C for 10 minutes. Remove heat and allow to cool. You may be lucky and find a regular source of WVO that doesn't need to have the water boiled off, in which case don't do it -- boiling means extra energy and time.

Personally I don't boil off the water first, I'd rather avoid the extra step in the process and save the energy it uses. But unless you're sure, it may be better to be on the safe side. Titration To determine the correct amount of lye required, a titration must be performed on the oil being transesterified.

This is the most difficult step in the process, and the most critical -- make your titration as accurate as possible. The lye must be dry -- keep it away from water, store it in an airtight container. Make up a solution of one gram of lye to one liter of distilled water.The HASPI Curriculum Resources are available free for use by educators.
