MF： C4H10O2
MW： 90.12
CAS： 107-88-0
1,3-Butanediol, abbreviated as 1,3-PDO, has good hygroscopicity, odorless, low toxicity, and water retention
It has the characteristics of good solubility and also has the reactivity of binary alcohols. Mainly used for the production of plasticizers, not
Saturated polyester resin, industrial dehydrating agent, etc; Can be used in cosmetics
As a humectant, it is used in cosmetics, cream, lotion, gel, toothpaste and other products;
It can also be used as a humidifier and softener for textiles, tobacco, and paper, as well as for the resistance of cheese or meat
Bacterial agents, etc.
Application:
Used as a soft lubricant and also for organic synthesis purposes, 1,3-butanediol has the reactivity of diols
It has the characteristics of odorless, low toxicity, and good water solubility, and can be used in the following main aspects:
1. Used as a polymer
Unsaturated resin obtained by mixing 1,3-butanediol or ethylene glycol as raw materials for ester resin and alkyd resin
Polyester has good water resistance, softness, and impact resistance.
2. Raw materials used as plasticizers
A polyester plasticizer prepared from 1,3-butanediol and dicarboxylic acid (adipic acid), with low volatility
Hair resistance, migration resistance, soapy water resistance, solvent resistance, and oil resistance.
3. Used as a polyurethane coating
As a raw material for polyurethane coatings using saturated polyester, the resulting product is in unpainted condition
It can achieve good water resistance, which is better than using other binary alcohols.
4. Used for wetting
The agent and softener 1,3-butanediol have excellent moisturizing and low toxicity, and can be used after being made into esters
Used as a wetting and softening agent for vinylon films, paper, and fibers.
5. As a solvent for fine chemicals, it can be used in cosmetics, ointments, creams, and toothpaste Etc.
1,3-butanediol is also an intermediate in pharmaceuticals and dyes. Purpose: To manufacture polyurethane. Surfactants, plasticizers, coupling agents, solvents, food additives, and spices.
