2、 Physical properties

BDO is a colorless, viscous, hygroscopic liquid with high boiling and melting points, and is easily soluble in polar solvents such as water, methanol, and ethanol. These physical properties make BDO exhibit good solubility and stability in many applications. The low volatility and high viscosity of BDO also make it ideal for specific applications.

3、 Chemical properties

BDO contains two hydroxyl groups (- OH), with strong nucleophilicity and reducibility, and can participate in various chemical reactions such as esterification, condensation, oxidation, etc.

Esterification reaction: BDO reacts with acids to produce corresponding ester compounds.

Condensation reaction: Under the action of a catalyst, BDO undergoes condensation reaction with compounds such as amines and aldehydes, generating various derivatives.

Oxidation reaction: BDO can be oxidized to produce products such as gamma butyrolactone or succinic acid.

4、 Purpose:

BDO has a wide range of applications, mainly including the following aspects:

Synthetic polymer: BDO is an important monomer for producing high-performance plastic polybutylene terephthalate (PBT), as well as for producing thermoplastic polyurethane (TPU) and other copolymers. PBT plastic is one of the five most promising engineering plastics.

Solvent: Due to its good solubility, BDO is used as a solvent for various resins, coatings, dyes, and paints.

Intermediate: BDO is the main raw material for producing tetrahydrofuran (THF), which is also an important intermediate for synthesizing elastomers and solvents. The poly (tetramethylene glycol) ether (PTMEG) obtained after polymerization is the basic raw material for producing high elasticity spandex (Lycra fiber). Spandex is mainly used in the production of high elasticity knitwear such as high-end sportswear and swimwear.

Medicine and cosmetics: BDO can be used to produce drugs such as vitamin B6 and dehydroepiandrosterone (DHEA), as well as used as a moisturizer and lubricant in cosmetics.

Other applications: BDO can also be used to prepare N-methylpyrrolidone, N-vinyl pyrrolidone, and other pyrrolidone derivatives, as well as pesticides, herbicides, plasticizers, lubricants, wetting agents, softeners, adhesives, and brighteners for the electroplating industry.
