Once it’s been transesterified, canola oil is ready for use in the engine. Nonetheless, it still has one big disadvantage. Like any vegetable oil, biodiesel can also go rancid. When this happens, the oil reacts with oxygen in the air and forms acids and solids, so-called gums. As these can damage the engine, the fuel is essentially unusable. That’s where Baynox® comes in. LANXESS has developed this biodiesel additive to make the “green fuel” every bit as long-lasting as conventional fossil diesel. In short, Baynox® prevents biodiesel from becoming rancid. Equipped with the synthetic antioxidant, biodiesel can be stored and transported without problems. And end users can fill up their tanks without worrying about the fuel in the tank “going off.” At the end of 2006, LANXESS also launched Baynox® plus on the market – a product that can preserve particularly sensitive forms of biodiesel such as those produced from soya or sunflower oil.
