  • Patent number: 11597951
    Abstract: Methods for the preparation of bio-based malonic acid and diester derivatives of malonic acid are provided. For example, a dialkyl malonate may be prepared by the steps of (i) separating calcium malonate crystals from a fermentation broth; (ii) obtaining dissolved malonic acid; (iii) crystallizing the dissolved malonic acid; and (iv) performing esterification to obtain the dialkyl malonate. The disclosed methods produce diester derivatives of malonic acid with fewer impurities, which is useful for many industrial processes. The diester derivatives of malonic acid can be purified from existing sources of malonic acid, or from malonic acid made from a renewable carbon source.

  • Publication number: 20230023780
    Abstract: A process for the preparation of bio-based malonic acid and crystalline calcium malonate is provided. The calcium malonate is highly pure and provides a source of malonic acid made from a renewable carbon source rather than existing processes which rely on the use of petroleum-based products. The calcium malonate provides an improved source of malonic acid, which is important to many industrial processes.

  • Patent number: 10611903
    Abstract: Polymer systems comprising poly(vinyl chloride), a non-petroleum based filler, and a polyester additive, wherein the polymer system is highly filled, and articles made therefrom, are described. The high loading of filler (e.g., talc, calcium carbonate or a combination thereof) is achieved by incorporation of polyester additives such as polyhydroxyalkanoates. High filler loading without significant reduction of relevant material properties can be associated with cost savings and environmental benefits.
