Biodiesel has become an important component of modern fuels. For good reasons: it is sourced from renewable materials (incl. waste) and ensures reduced GHG emissions. The utilization of biodiesel reduces the use of fossil fuels. Today's biodiesel blends satisfy engine manufacturers' call for high-quality, powerful and economic fuels. Such Biodiesel is made from vegetable oils, animal fats or used cooking oils (besides other waste materials). These conversion processes require catalysts. BASF's high-quality sodium and potassium methylate are ideal to convert these renewable materials into high performing biofuels.

Sodium and potassium methylate are efficient and reliable catalysts that provide a sustainable solution for the production of crop protection agents, pharmaceutical agents and biodiesel. 

Our products for the biodiesel industry meet the requirements of engine manufacturers for high-quality fuels and lower emissions. Both products support higher yields and low preparation cost for biodiesel and are produced at BASF's Ludwigshafen Verbund site. Sodium methylate is also produced in Guaratinguetá, Brazil.

A 30 % sodium methylate solution in methanol is the most commonly used catalyst to enable transesterification processes of triglycerides. The more reactive 32 % potassium methylate solution is used in the transesterification of special oils and greases. Both products are available in methanol as fully formulated, ready-to-use solutions.

For Life-sciences, sodium and potassium methylate are also being produced as methanol-free crystals. These are perfectly adapted for the need of Agrichemicals producers and similar complex chemical synthesis: such processes perform best in the absence of water, methanol or any other alcohol. Our crystalline alcoholates have been specifically tailored for these high demands and can thus be employed as stoichiometric reagents/bases in such demanding chemical synthesis.

At our Ludwigshafen site we also produce sodium ethylate. It is available as 21% solution in ethanol or in its ethanol-free, concentrated crystalline form. Typically, sodium ethylate is used to extract highly concentrated Omega-3 fatty acids from fish oils. However, our product is not limited to these processes but can be employed in any ethylester transesterification process, substitution reaction or when simply bases with higher solubility in chemical solvents are required.

With a unique range of benefits for the pulp and paper industry, Adlite® offers new ways to approach thermomechanical pulping (TMP). Adlite® provides a brightness gain comparable to oxidative bleaching, a higher wood yield, substantially lower energy consumption, and less demand of chemicals in the entire production process from stock preparation to wastewater treatment. In addition, Adlite®'s stabilization system will allow refiners to optimize production processes and cost structure, while providing extra degrees of freedom to design paper grades.

In more details, Adlite® is the first reductive solution to offer a degree of brightness comparable to oxidative bleaching while keeping the uniformity of the wood fiber intact. Adlite® facilitates a smooth separation of the fibers out of the wood structure. Whereas the oxidative process requires the handling of various additional chemicals, Adlite® just adds just one substance to your paper production and thus, allows safe and easy handling. Since Adlite® offers high selective reaction control, no unwanted side reactions occur during the process. This avoids corrosion and deposits and your refiners run trouble-free with higher productivity for a longer period of time. The quality of your final product is much less dependent on the quality of the wood. Adlite® preserves the wood fiber during the milling process, the desired paper grade can be achieved with less energy and wood consumption. The same goes for the bleaching process: more ISO brightness for less energy. In general, Adlite® makes it much easier to meet environmental requirements.
