Dibasic Esters for Chemical Applications

N/Aer (DBE) and its fractions serve as raw materials for plasticizers, polymers. wet strength paper resins and other specialty chemicals. These applications are growing rapidly as new uses are found for DBEs as building blocks.

Applications:

• Plasticizers- Certain esters of adipic, glutaric, and succinic acids (as mixtures or individually) are excellent plasticizers for various polymer systems including polyvinyl chloride resins.

  Polymer Intermediate- As a source of adipic, glutaric and succinic acids and their mixtures, Diabasic Esters provide unique polymer structures. By the selection of the proper DBE fraction, properties, such as low temperature flexibility, can be tailored to meet specific needs.

• Polyester Polyols for Urethanes- Polyols based on DBE are used to make polyurethane elastomers, coatings and both flexible and rigid foams.

• Wet-Strength Paper Resins- DBE-2, DBE-5, and DBE-9 are particularly useful in the preparation of long-chain water soluble polyamides of the type which can be reacted with epichlorohydrin to form wet-strength paper resins.

• Polyester Resins- DBEs are used extensively in the manufacture of saturated and unsaturated polyester resins.

• Specialty Chemical Intermediate- Dimethyl succinate (DBE-4), dimethyl glutarate (DBE-5) and dimethyl adipate (DBE-6) are abundant and economical sources of the adipic, glutarate and succinic moieties for organic synthesis.
