Abstract: Biobased p-cymene and methods of producing same, which can further be converted to terephtalate. Further, a method is described for converting crude sulfate turpentine recovered from chemical wood pulping into p-cymene and eventually to terephtalic acid of biological origin, and products thereof respectively. In said method, both conversion and desulfurization is realized in one reaction step. The disclosure is also related to use of zeolite catalysts in said method.

Abstract: The invention refers to a method for forming particles or droplets of at least one substance comprising the steps of providing a foamed medium, which foamed medium comprises said substance, and forming particles or droplets of said substance at least partly by electrostatic processing. The use of foamed medium in electrostatic processing enables higher production speeds and increases the evenness of a coating layer formed by electrospinning or electrospraying the particles or droplets on a substrate.
