Titration of Biodiesel and Titration Instruments

Titration of biodiesel is a chemical procedure that uses lye, isopropyl alcohol, distilled water, phenolphthalein in order to measure the pH content of your used vegetable oil.

Biodiesel titration can help you do calculations on the amount of sodium hydroxide you will need as a catalyst in the performance of the biodiesel process.

Biodiesel titration is an essential part of biodiesel preparation especially when you are using used vegetable oil. WVO can be taken for a small fee or for free from restaurants around your area. The only downside when using WVO is that once it is heated, it has the property to create free fatty acids. In addition, it becomes more acidic than SVO (straight vegetable oil).

The glycerin found in oil enables it to become thick and unfit for burning in a regular engine. During the biodiesel process, the glycerin within the oil is replaced with methanol.

The biodiesel titration formula for creating biodiesel fuel from SVO using a catalyst that contains 100% purity is this: 7 grams potash per liter of oil + oil + 20% methanol. The titration method is performed by soaking the sodium hydroxide to a solution of waste vegetable oil and alcohol. This process is normally 1ml of vegetable oil into 10 ml of isopropyl alcohol.

The biodiesel titration kit provides step by step instructions as to how to perform the needed titration procedure. The goods needed for the titration procedure are available elsewhere. A kit includes everything. They even provide measuring devices and eyedroppers.

Biodiesel titration calculator will determine the amount of catalyst or lye needed to produce the biodiesel. Virgin oil from any plant type requires a portion of lye equivalent to about 1% to the weight of the vegetable oil. This translates to 3.5 grams of the catalyst or lye per liter of the plant oil. To illustrate the work, this is how the biodiesel titration chart will tell you. If it needs 3m of .1% solution of lye, to complete the oil and isopropyl alcohol solution to enter the process of titration, it will require you to put in 3 grams of the sodium hydroxide to 3.5 grams for the virgin oil, or 6.5 grams sum total per liter of waste oil.

Here are basic steps in biodiesel titration test:

• Take an oil sample.

• Pour isopropyl into 3 beakers.

• Put 3 drops of phenolphthalein into each of the beaker.

• Slowly add test solution to the beaker until the isopropyl turn pink.

• Put 1ml of the oil that has to be titrated in each flask.

• Dissolve the air by swirling it around.

• Add the test solution until the color turns to purple for a period of at least 20 seconds. Record the reading on a sheet of paper.

• If the result of the three tests has a discrepancy of more than 5%, repeat the test.

• Make an average of the 3 readings.

• Each ml of the result translates to 1g of added catalyst.

• Multiply it with the number of liters of oil.

• Use 22% of methanol in the process.

• You can now make the necessary adjustments and start producing biodiesel.
