1,2-Benzenedicarboxylic acid, mixed cyclohexyl and 2-ethylhexyl esters - Introduction
1,2-benzenedicarboxylic acid, mixed cyclohexyl and 2-ethylhexyl esters, also known as DEHP(Diethylhexyl phthalate), is an organic compound. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
1,2-Benzenedicarboxylic acid, mixed cyclohexyl and 2-ethylhexyl esters is a colorless to pale yellow liquid with a low vapor pressure. It is insoluble in water but soluble in most organic solvents. This compound has a melting point of -50°C, a boiling point of 385°C and a density of 0.986g/cm³.
Use:
DEHP is mainly used as a plasticizer in plastics, especially a softener for polyvinyl chloride (PVC). It can increase the flexibility and ductility of the plastic, and improve the abrasion resistance and cold resistance of the plastic. DEHP is also used in the manufacture of coatings, tapes, adhesives and medical supplies, food packaging materials.
Method:
1,2-benzenedicarboxylic acid, mixed cyclohexyl and 2-ethylhexyl esters are generally prepared by esterification catalyzed by acetic acid in the presence of esterification reagents such as phthalic anhydride and cyclohexanone or 2-ethylhexanone. The specific preparation method can refer to the relevant chemical literature.
Safety Information:
DEHP is considered to be a suspected human endocrine disruptor, which may have certain potential risks to human health. Long-term exposure to high concentrations of DEHP may have adverse effects on the reproductive system, liver and lungs. In addition, DEHP may release harmful gases in a high-temperature, high-humidity environment. Therefore, excessive exposure and inhalation of DEHP should be avoided. When using DEHP or contacting products with this compound, appropriate safety measures should be taken, such as wearing protective gloves and breathing equipment, and ensuring good ventilation.
