    Re: using glycerine in bio gas digester

    Using medical grade glycerine I made glycerol triacetate. I think it's a fuel additive. It's worth more than glycerine, it's good for something, rather than being waste product. The formula I...

    Sticky: Re: The Warnqvest Test and re-processing

    Generally the higher the molecular weight an organic chemical has the lower the vapor pressure. In considering synthetic fuel made from vegetable oil, relatively positive and negative polarity areas...

    "1 KG KOH in 20 litres of methanol produces 320 gms of water (1.6%) plus any water in the methanol." Not exactly. Most KOH is not 100% pure. My KOH is 85% pure. But if your KOH is 90% pure then 1...
