BDO(1,4-butanediol) is an important organic chemical raw material, which is widely used in the field of chemical production. This article will detail the nature and use of BDO. The properties of

1. BDO

BDO is a colorless, transparent, sweet viscous liquid with high boiling point and melting point. It is insoluble in water but miscible with many organic solvents. BDO is highly hygroscopic and corrosive, so it needs special attention during storage and transportation.

the chemical properties of BDO is more active, can occur a variety of reactions, such as esterification, etherification, condensation and other reactions. In addition, BDO also has good thermal stability and oxidation resistance, and can be stable under high temperature and aerobic conditions.

2. BDO USES

1. Production of PBS, PBT and other engineering plastics

BDO is an important raw material for the production of PBS, PBT and other engineering plastics. PBS is a biodegradable plastic with excellent processing performance and environmental protection. It is widely used in packaging, tableware, agricultural film and other fields. PBT is a kind of high temperature resistant, chemical resistant engineering plastics, used in the manufacture of electronic appliances, automotive parts and so on.

2. Production of tetrahydrofuran

BDO can be converted to tetrahydrofuran (THF), which is an important solvent and chemical raw material for the production of polyurethane, polymers, pharmaceutical intermediates, etc.

3. Production of γ-butyrolactone

BDO can also be converted into γ-butyrolactone (GBL), which is a high boiling point solvent used in the production of pesticides, pharmaceutical intermediates, pigments, etc.

4. Other uses

In addition to the above uses, BDO can also be used for the production of plasticizers, stabilizers, antioxidants and other chemicals, as well as for the manufacture of fibers, films, coatings and other fields.

In conclusion, as an important organic chemical raw material, BDO has a wide range of applications in the field of chemical production. With the continuous progress of science and technology and the improvement of people's awareness of environmental protection, the use of BDO will continue to expand, bringing more contributions to human production and life.
