    Re: My first wash. AARGGHH

    Hi Cade,

    Thank you for your vote of confidence, you have made me blush.

    Typically people wash several times before drying.
    If you go back and look at the picture I posted of the biodiesel in...

    Re: My first wash. AARGGHH

    Hi Wesley,

    Just washed biodiesel with lots of water still in suspension looks like "Orange Juice". You do have to agitate to thoroughtly mix the biodiesel and water.

    Re: My first wash. AARGGHH

    Hi Cade,

    I can not recall that I have ever used an acid to break an emulsion.
    My thoughts are that you should use as little as possible that will do the job you are after.

    Re: My first wash. AARGGHH

    Hi Cade,

    I think you have answered your own question.
    I would just let it sit and see if the emulsion breaks on it's own, then remove water and continue to heat. Otherwise you know vinegar...

    Re: My first wash. AARGGHH

    PS, I just noticed that Neutrals yields followed very closely Neutral's "rule of thumb" that says soap will take about twice it's volume of biodiesel into the waste/ glycerin.

    Hi Bueff,

    Adding water to the mix at the end of the reaction before draining the glycerin was first suggested by the people at Idaho university. Their initial recommendation was 15% water which...

    Re: My first wash. AARGGHH

    Hi Cade,

    In your situation, instead of heating the biodiesel until it clears and then allowing to cool, just remove the water that settles out when the biodiesel clears and continue heating.
    I...

    Re: My first wash. AARGGHH

    That is strange, I replied a couple hours ago and it disappeared.
    Second attempt.

    A lot of water will have fallen out by the time the biodiesel has cleared during the initial heating..
    At this...

    Re: My first wash. AARGGHH

    Hi cade,

    If you want to heat your biodiesel to "force" dry it, anything up to 100C should be fine.




    You could make, settle, wash and dry in 24 hours if you wanted to. The biggest slow...

    Re: My first wash. AARGGHH

    Hi Cade,
    "Orange Juice" is a typical look for water washed biodiesel.
    My experience is that, depending on the temperature and the radio station you are listening to, it will take a day or ten for...

    Re: Timing on Mercedes engine

    Hi Chevy28.
    Yes I see. I did have several websites open yesterday looking for the info.
    All the info I can find today says both the Auto and the Manual do 0- 100 in 16 seconds.

    Hi Arvin,
    When I was making 20 litre batches of biodiesel I used a 2 litre plastic container with measurements marked on the side.
    Fill it up 10 times to the 2 litre mark and you have 20 litres...

    Re: Timing on Mercedes engine

    Hi Tony,

    I see.
    So you think that the 190 I linked to was actually much speedier than the 190 sold in Australia.
    0- 100 in under 30 seconds is pretty good...

  17. Re: Foolproof Room Temperature (FRT) Biodiesel

    Hi Mark

    But you only recently increased the KOH from 15g to 20g. Maybe you need to further increase the amount of KOH you are using- say to 25g or 30g KOH per litre of oil....

  20. Re: The chemistry of the glycerol (and soap) phase

    Hi Mark,

    An inaccurate statement. Even if your method does remove all the water produced when making methoxide, and you have never shown any testing to support this claim, you keep omitting to...
