Standard-For Good Reason

        Sodium methylate is a versatile chemical reagent that's been used for many decades in various industries to produce high-value end products like pharmaceuticals, food ingredients, pigments and crop-protecting agents. It's also the catalyst of choice for most biodiesel producers.
        The most prevalent process for the production of biodiesel-or chemically, the conversion of triglycerides to the corresponding methyl ester-is transesterification by homogeneous alkaline catalysis. Catalysts that can be used in this process include caustic soda (sodium hydroxide), caustic potash (potassium hydroxide) and sodium methylate.
        Sodium methylate has become the catalyst of choice for modern large-scale biodiesel production accounting for more than 70 percent of the biodiesel produced in North America. All major technology providers including Lurgi PSI, Desmet Ballestra and Crown Iron Works offer biodiesel process technologies and plant designs that utilize sodium methylate. In addition, an increasing number of biodiesel producers are switching to superior water-free sodium methylate solutions from traditional solid catalysts like sodium or potassium hydroxide.
