1,5 Pentanedial, also known as Glutaraldehyde or glutaral is an organic compound with the formula OCH(CH2)3CHO.
1,5-Pentanedial is used as a disinfectant for sterilization of heat-sensitive equipment and as a laboratory reagent, especially as a fixative.
At room temperature 1,5-Pentanedial is a pungent colourless oily liquid and is mainly available as an aqueous solution of 50% concentration.
Being non-volatile and bifunctional, 1,5-Pentanedial is often preferred to the less expensive formaldehyde.
1,5-Pentanedial reacts with amines, amides, and thiol groups in proteins.
A 1,5-Pentanedial solution of 0.1% to 1.0% concentration may be used as a biocide for system disinfection and as a preservative for long term storage.
1,5-Pentanedial is a sterilant, killing endospores in addition to many microorganisms and viruses.
1,5-Pentanedial is also used for industrial water treatment and as a chemical preservative.
Preparation Method
The hydrolysis synthesis was carried out by reacting acrolein with vinyl ether.
From acrolein and acetic ether with zinc salt as catalyst, at 90 ℃, 0.
Under the pressure of lMPa, the ring into 2 a ethoxy group 3,4-= hydrogen pyran, and then by hydrolysis of ring opening, the conversion rate of 95%.
Use
In oilfield chemicals, 1,5-Pentanedial can be used as a bactericide for water-based oil well fracturing fluid, a crosslinking agent for cellulose, etc.
1,5-Pentanedial as a water treatment bactericide can be widely used in the circulating water system sterilization, can effectively control the number of microorganisms in various water systems, can effectively strip the biological slime and biofilm, the input amount is generally 50 to lOOmg/L.
1,5-Pentanedial has the advantages of quaternary ammonium salt series bactericide, no foaming, easy to use, good compatibility with corrosion inhibitor.
In actual use, 1,5-Pentanedial is often used in combination with other drugs such as quaternary ammonium salts.
