Lanxess introduces new Baynox stabilizers for biodiesel

By Ron Kotrba | January 27, 2015

Lanxess Corp. announced it has added two new highly concentrated antioxidants to its line of biodiesel stabilizers. The new products, Baynox Ultra and Baynox Cargo, were introduced to the U.S. market at the National Biodiesel Conference & Expo this month in Fort Worth, Texas.

Baynox Ultra is especially formulated for soybean and sunflower biodiesel, according to the company. It contains a blend of highly active antioxidants and a chelating agent dissolved in a “green” solvent. With an active content of more than 40 percent, the typical dosing of Baynox Ultra ranges from 200 to 500 ppm. The stabilizer does not crystallize so it can be used at temperatures as low as 20 degrees Fahrenheit.

Baynox Cargo is a solution of the established Baynox antioxidant in an organic solvent, which has been developed as an oxidation stabilizer for the treatment of biodiesel cargos. It has an active content of more than 35 percent. The solution has a low viscosity and a flash point above 140 F for easy handling. It remains liquid at 20 F.

“The highly concentrated antioxidants Baynox Ultra and Baynox Cargo ensure that the biofuel obtained from natural raw material remains stable and can be used for longer,” said Tony Mazzarella, NAFTA Business Manager. “Otherwise, the fuel's unsaturated fatty acid structures can easily oxidize in contact with atmospheric oxygen. Heat, light and pressure make the oil rancid within a short time.”

Oxidation causes degradation of biodiesel and leads to gum formation, which can cause damage to diesel engines and injection systems. The pressures in diesel engines are continually rising, as are the injector temperatures, as biodiesel specifications continue to get tighter. “With Baynox Ultra, our customers will be ideally equipped to meet the demands of modern fuels made by the automotive industry,” Mazzarella said.
