68515-52-6 - Introduction
1,2-Benzenedicarboxylic acid, mixed 2-ethylhexyl and isodecyl esters, abbreviated DEHID, is an organic compound. It is an ester compound made by mixing 1,2-phthalic acid with 2-ethylhexanol and isodecanol.
Nature of DEHID:
-Appearance: Colorless to light yellow transparent liquid
-Solubility: Soluble in common organic solvents, such as alcohols, ketones and ethers.
-Melting point: approx. -30°C
-Boiling point: about 350°C
Use of DEHID:
DEHID is mainly used as plastic additives and plasticizers, especially in polyvinyl chloride (PVC) products. It can increase the flexibility, heat resistance and weather resistance of PVC products, and improve its aging resistance. In addition, DEHID is also used in the preparation of synthetic resins, coatings, adhesives and other industrial applications.
Preparation of DEHID:
DEHID is prepared by esterification of 1,2-benzenedicarboxylic acid with 2-ethylhexanol and isodecanol. Generally, such reactions require the presence of a catalyst and are carried out under appropriate temperature and reaction conditions.
Security information for DEHID:
- DEHID is irritating to human skin and eyes and should be washed thoroughly after contact. Appropriate personal protective measures should be taken during use, including wearing protective glasses and gloves.
-Avoid inhaling DEHID vapors and ventilate if necessary.
- DEHID is volatile and should be stored in a sealed container, away from heat sources and open flames.
-When using and storing DEHID, follow the relevant safety procedures and recommendations.
