Is the Corrosiveness of Tetrahydrofuran Related to Concentration

 Is the corrosiveness of tetrahydrofuran related to concentration?

The corrosiveness of tetrahydrofuran is related to concentration.
20% tetrahydrofuran solution applied directly to human skin can cause moderate skin irritation, 50% aqueous solution can cause severe corrosive damage, and 20% aqueous solution applied to human eyes can cause severe corneal damage.
The concentration of tetrahydrofuran needs to be prepared according to actual needs. For example, in gas chromatography, the concentration of tetrahydrofuran is usually 50~200ppm. You can also choose tetrahydrofuran without BHT stabilizer.
Tetrahydrofuran is not easy to volatilize at around 4 degrees.
Tetrahydrofuran is a commonly used organic compound that is volatile to a certain extent, but does not evaporate as quickly as flammable and explosive compounds. The boiling point of tetrahydrofuran is 64 to 66 degrees. It is not volatile at room temperature, but at about 4 degrees, its volatility may be less than at room temperature.

1.4-Butanediol

1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.

Tetrahydrofuran

Tetrahydrofuran (THF) is a colorless, volatile liquid with the odor of ether or acetone and is miscible with water and most organic solvents. THF is highly flammable and may thermally decompose into carbon monoxide and carbon dioxide.

BDO

图片
1.4-Butanediol ( BDO ) is used industrially as a solvent and in the manufacture of certain types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1.4-butanediol is used in the synthesis of gamma-butyrolactone (GBL). In the presence of phosphoric acid and high temperatures, 1.4-Butanediol dehydrates into the important solvent tetrahydrofuran. At about 200°C, in the presence of a soluble ruthenium catalyst, the diol undergoes a dehydrogenation reaction to form butyrolactone. BDO is used to synthesize 1,4-butanediol diglycidyl ether, which is then used as an epoxy resin diluent.
