说明

應用

• Biopolymer synthesis: Illustrated by the extractive adsorption study of Sui et al., where 1,3-Propanediol was effectively isolated using novel resin technologies. This application is crucial for the sustainable production of biopolymers, impacting sectors from industrial manufacturing to biotechnology (Sui WB et al., 2023).


• Hydrogenation processes in chemical synthesis: Examined by Zhang et al. in the development of bimetallic catalysts for the efficient hydrogenation of diethyl malonate to 1,3-Propanediol. This research is relevant for chemists and researchers looking to optimize reaction processes for producing high-value chemicals in a sustainable manner (Zhang J et al., 2024).


• Enhancement of microbial production systems: Explored by Jiang et al., where the inactivation of specific metabolic pathways in Klebsiella pneumoniae led to enhanced production of 1,3-Propanediol. This is crucial for the biotechnological production of this compound, offering insights for principle investigators and researchers focused on metabolic engineering and industrial biotechnology (Jiang W et al., 2024).
