Latest Patents
One of Yabune's latest patents is a method for producing acetylated pyroxylin. This invention provides a safe and cost-effective approach by utilizing inexpensive water-wetted pyroxylin instead of the more costly alcohol-wetted pyroxylin. The process involves dehydrating the water-wetted pyroxylin in the presence of a nonalcoholic non-solvent for pyroxylin, followed by the application of an acetylating agent. The first dehydration process disperses the water-wetted pyroxylin in a nonalcoholic dispersing medium and then dehydrating it through distillation. The second process involves adding a replacing agent to the water-wetted pyroxylin, which is then dehydrated by filtration. Both methods ensure safe dehydration of the pyroxylin.
Another significant patent is a process for producing cellulose diacetate. This process outlines the steps necessary for the efficient production of this important chemical compound, further showcasing Yabune's expertise in chemical processes.
