Usage

General Description

1,2,3,6-Tetrahydrophthalic acid di(2-ethylhexyl) ester is a chemical compound commonly used as a plasticizer in the production of various plastic and resin-based products, including PVC pipes, flooring, and wire coatings. It is also used in the manufacturing of adhesives, sealants, and certain types of paint. This chemical is known for its ability to improve the flexibility and durability of plastics, making them less prone to cracking and brittleness. However, 1,2,3,6-Tetrahydrophthalic acid di(2-ethylhexyl) ester has been associated with potential health risks, including irritation to the respiratory system and skin, and may also have adverse effects on aquatic life when released into the environment. Therefore, it is important to handle and dispose of this chemical with caution and in accordance with relevant safety regulations.

Synthesis of 1,4-Cyclohexanedimethanol, 1,4-Cyclohexanedicarboxylic Acid and 1,2-Cyclohexanedicarboxylates from Formaldehyde, Crotonaldehyde and Acrylate/Fumarate

Valuable polyester monomers and plasticizers—1,4-cyclohexanedimethanol (CHDM), 1,4-cyclohexanedicarboxylic acid (CHDA), and 1,2-cyclohexanedicarboxylates—have been prepared by a new strategy. The synthetic processes involve a proline-catalyzed formal [3+1+2] cycloaddition of formaldehyde, crotonaldehyde, and acrylate (or fumarate). CHDM is produced after a subsequent hydrogenation step over a commercially available Cu/Zn/Al catalyst and a one-pot hydrogenation/oxidation/hydrolysis process yields CHDA, whereas 1,2-cyclohexanedicarboxylate is obtained by a Pd/C-catalyzed tandem decarbonylation/hydrogenation step.
