3. نطاق التطبيق والاستخدام
1,4-Butanediol is widely used as a solvent in the paint, ink, and coating industries. It also serves as an intermediate in the production of polyamides, polyurethanes, and elastomers. Additionally, it is used in the synthesis of pharmaceuticals and as a humectant in cosmetics. It is a key ingredient in the production ofγ-Butyrolactone and N-Methyl-2-pyrrolidone。
4. العبوة والتخزين
1,4-Butanediol is typically packaged in 25 kg net weight polypropylene bags with polyethylene film liners。It should be stored in a cool, dry place away from heat sources and direct sunlight to prevent evaporation and degradation. The storage area should be well-ventilated to minimize the accumulation of vapors. The product should be kept away from strong oxidizing agents and acids. Appropriate safety measures should be taken to prevent contamination and ensure safe handling。
