Home Products Applications 1,4-Butanediol
1,4-Butanediol
In the value transformation of 1,4-butanediol (BDO) from a basic chemical to high-value-added materials (e.g., polyurethane, biodegradable plastics), high-efficiency catalysts are the key driver for the entire industrial chain, directly determining production efficiency, product purity, and overall cost. Therefore, developing higher-performance catalysts is the core breakthrough for achieving green and economical BDO synthesis.
