Thread Content

On March 16, the first phase of Liaocheng Huanuo Biomass Materials Co., Ltd.’s project to produce 50,000 tons per year of the bio-based new material monomer 1,5-pentanediol entered the environmental impact assessment approval stage. Project Name: 50,000 tons/year Bio-based 1,5-Pentanediol Project (Phase I)
Constructor: Liaocheng Huanuo Biomass Materials Co., Ltd.
Product Profile: Bio-based 1,5-pentanediol (PDO), a high-end bio-based diol used in industries such as cosmetics, polyesters, polyurethanes, and plasticizers.
Raw Material Route: Agricultural waste such as corn cobs and straws is used as raw material; bio-based 1,5-pentanediol is produced through the process of furfural/furfuryl alcohol → tetrahydrofurfuryl alcohol → hydrogenation and refinement. 1,5-Pentanediol is a colorless and transparent viscous liquid with two primary hydroxyl groups, and its properties lie between those of 1,4-butanediol (BDO) and 1,6-hexanediol (HDO). Key applications: 1. Polymers and polyurethanes (PU): Used as raw materials for synthesizing non-phthalate plasticizers such as 1,5-pentanediol dibenzoate, and applied in PVC, acrylic resins, etc., to endow products with good low-temperature resistance and flexibility. It can also be used to produce polyester polyols, which are then used to manufacture polyurethane elastomers, adhesives, and coatings. 2. Solvent: It has good solvating power for various organic substances, a high boiling point (~242°C), and slow evaporation; it can be used in high-performance coatings, inks, and cleaners. 3. Synthetic intermediates: Used for the synthesis of important chemicals such as pyridine, glutaric acid, and hydroxycarboxylic acids. 4. UV-curable materials: As reactive diluents or monomers for synthesizing UV-curable oligomers. Synthesis routes of 1,5-pentanediol: Route 1: Catalytic hydrogenation of glutaric acid/glutarate (the mainstream method); Route 2: Hydrogenation of furfural (a biomass-based platform molecule); Route 3: Hydroxymethylation of tetrahydrofuran (THF)
