How does the addition of concentrated ethanoic acid help remove any soap that is formed?

I know that soap is commonly formed when excess base is still present during the water washings of the oil. To prevent this a small amount of concentrated ethanoic acid is added to neutralise the oil.

I need a more detailed explanation though so any help would be appreciated! Thanks.

5,000 acres of land in the State of Yucatan in Mexico being cleared to cultivate crops for biodiesel.

I am researching the mechanics of making biodiesel and contemplating buying a ready-to-assemble processor. It sounds like a great idea but I would like input from people who already have experience with this.( For example, is it easy to make or is it a hassel? Does it work well in your diesel engine? How much petrol diesel do you have to mix with it in the winter?) Any opinions would be greatly appreciated.

Im looking for a place or online site somewhere where I can purchase an algal strain for creating biodiesel. I’ve looked at two different strains Chlorella protothecoides and Dunaliella Salina but any algae strain that can produce biodiesel and has a relatively high lipid content would be ideal. Thanks in Advance.

I live in Phoenix, Arizona. Do you know of anyone who can convert my truck to biodiesel, and what do you need to do to convert a truck to biodiesel? I want to keep using my truck in an environmentally sound way, and I want to make a stand against using oil by not buying gasoline anymore!

Biodesel reqiures land to be cultivate, that means it will occupy the area of agricultural farms which is not possible, since we need more food to feed our growing population. so the other option is to clear forest area to cultivate these plants, it is not wise to go for biodiesel at the cost of forest area. also, the number of vehicle is increasing day by day that means the emmission of pollutant will increase. it is better to go for renewable source of energy than the biodiesel.

The Mazda 5 is just begging to go hybrid in my opinion, and these gas guzzlers, (which are often used for singular purposes, not just soccer,) must be tamed. Don’t you think?
Sure it would cost more but we’re really nailing the technology. I understand in Europe there is a diesel Chyrsler minivan, and it goes. Bring it here, we’ve got biodiesel now.
Do minivans user’s really race stop light to stop light?

With fuel prices going up do you think that biodiesel can make it right now? Will higher feedstock prices outweigh the increased cost of biodiesel?
