    Abstract: REFINO CATALÍTICO DE TERPENOS DE ORIGEM DE POLPA. A presente invenção está correlacionada a um composto de p-cimeno de origem biológica, que pode ser ainda convertido em tereftalato. Além disso, é descrito um método para conversão de sulfato de bruto de terebentina (aguarrás), recuperado de polpação química de madeira, em p-cimeno e, eventualmente, em ácido tereftálico de origem biológica e derivados do mesmo, respectivamente. No dito método, as etapas de conversão e dessulfurização são realizadas em uma única etapa reacional. A presente divulgação é tambem correlacionada ao uso de catalisadores de zeólito no referido método.

    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 translation: 生物基对异丙基异丙苯及其制备方法，可进一步转化为对苯二甲酸酯。 此外，描述了将从化学木材制浆中回收的粗硫酸盐松节油转化为对甲基异丙基苯并最终将其转化为生物来源的对苯二甲酸及其产物的方法。 在所述方法中，在一个反应​​步骤中实现转化和脱硫。 本公开还涉及在所述方法中使用沸石催化剂。
