Application Scenarios & Case Studies

2-Butyne-1,4-diol (BOZ) demonstrates exceptional versatility in the following industries:

Petrochemical Industry: Used as a starting material for downstream products including butadiene, specialty rubbers, and plasticizers. Its robust structure and high reactivity hasten production throughput and reduced batch cycle times.
Electroplating & Surface Technology: Serves as a leveler and brightener in copper and nickel plating. Compared to competitors (e.g., TMEDA or 1,4-butanediol), BOZ delivers finer grain structure, improved leveling capacity, and reduced micro-pit formation (field-tested, 11% defect reduction²).
Fine Chemicals/Pharmaceuticals: Building block for anti-tumor, anti-viral, and specialty API intermediates. Its secondary reactivity enables advanced synthesis routes not accessible via standard diols.
Agrochemical/Pesticide Industry: Used in synthesis of selective herbicides and expert additives.
Polymer & Coatings Sector: Applied in polyurethane prepolymers for enhanced flexibility and corrosion resistance.

Case Study – Energy Saving in Industrial Plating

A high-volume electronics plating facility adopted 2-Butyne-1,4-diol (BOZ) as the major additive in 2022:
