Methods of making intermediates from polyhydroxyalkanoates

   
   

Methods of forming intermediates from PHAs are disclosed. In general, the methods include forming a pyrrolidone from a PHA, such as poly 4-hydroxybutyrate or a 4-hydroxybutyrate containing polymer. The methods can include, for example, treating (e.g., heating) the PHA to form a pyrrolidone. The methods can include, for example, treating a biomass containing the PHA to form a pyrrolidone. The methods can include, for example, heating the PHA to a temperature of at most about 90.degree. C. to form a pyrrolidone, wherein the percent yield of the pyrrolidone is at least about 50%.

Os métodos de dar forma a intermediários de PHAs são divulgados. No general, os métodos incluem dar forma a um pyrrolidone de um PHA, tal como 4-hydroxybutyrate poly ou um 4-hydroxybutyrate que contem o polímero. Os métodos podem incluir, para o exemplo, tratando (por exemplo, se aquecer) o PHA para dar forma a um pyrrolidone. Os métodos podem incluir, para o exemplo, tratando um biomass que contem o PHA para dar forma a um pyrrolidone. Os métodos podem incluir, para o exemplo, aquecendo o PHA a uma temperatura de a maioria sobre 90.degree. C. para dar forma a um pyrrolidone, wherein o rendimento dos por cento do pyrrolidone é ao menos aproximadamente 50%.
