全球首套！生物基 1,5 - 戊二醇工艺试验成功

Core Viewpoint - The article highlights the successful trial of the world's first bio-based 1,5-pentanediol production process by the company, which utilizes a unique one-step hydrogenation method, achieving high purity and meeting international standards [2][5]. Group 1: Production Process - The company has developed a bio-based 1,5-pentanediol production technology that demonstrates significant innovation by employing a special catalyst in a one-step hydrogenation process [5]. - The industrial production of 1,5-pentanediol can follow two main technological routes: a petroleum-based route and a bio-based route, both requiring strict control of reaction conditions to ensure product purity [3][4]. - The bio-based route uses cyclopentene as a raw material, undergoing a photoxidation reaction to generate an epoxy pentenal intermediate, followed by catalytic hydrogenation under specific temperature and pressure conditions [4]. Group 2: Product Quality and Standards - The final products from both production routes must meet cosmetic ingredient standards, including purity ≥ 99%, moisture content ≤ 0.1%, and heavy metal residue ≤ 10 ppm [5]. - The bio-based 1,5-pentanediol produced by the company has a purity exceeding 99.5%, with color and moisture content well within the required limits, showcasing its compliance with or surpassing international standards [2][5]. Group 3: Market Applications - Bio-based 1,5-pentanediol is widely used in high-end cosmetics due to its excellent moisturizing and preservative properties, aligning with consumer demand for natural and green products [6]. - In the biopharmaceutical sector, 1,5-pentanediol is crucial for synthesizing various pharmaceutical intermediates, meeting the stringent requirements of the industry [6]. - The compound also plays a key role in producing high-end polyurethane and polyester materials, which are utilized in electric vehicle battery coatings and high-value apparel materials, among other applications [6].
