1, 3-butanediol has the characteristics of reactivity, odorless, low toxicity, good water solubility, etc., and can be used in the following main aspects:

1. Used as the raw material of polyester resin and alkyd resin, unsaturated polyester made of 1, 3-butanediol or ethylene glycol is mixed with good water resistance, softness and impact resistance.

2. Polyester plasticizer made of 1, 3-butanediol and dibasic acid (adipic acid) as a raw material for plasticizer, with low volatility, migration resistance, soapy water resistance, solvent and oil resistance.

3. As the raw material of polyurethane coating as the raw material of saturated polyester for polyurethane coating, the obtained product can get good water resistance in the uncoated paint, and the effect is better than that of using other diols.

4. Used as wetting agent and softener, 1, 3-butanediol has excellent moisturizing properties and low toxicity. After being made into ester, it can be used as wetting and softener for cigarettes, celluloid, Vinylon film, paper and fiber.

5. Solvents used as fine chemicals can be used in the formulation of toners, creams, pastes and toothpastes. 1, 3-butanediol is also an intermediate in medicine and dyes
