1,2-Benzenedicarboxylic acid, di-C8-10-alkyl esters - Introduction
1,2-benzenedicarboxylic acid, di-C8-10-alkyl esters (also known as diisononyl phthalate, or DINP for short) is a common Ester compound. The following is a description of some properties, uses, methods and safety information about DINP:
Nature:
-Appearance: DINP is a colorless to pale yellow liquid.
-Density: The density of DINP is about 0.98-0.99g/cm³.
-Melting point: The melting point of DINP is about -45°C.
-Boiling point: The boiling point of DINP is about 379-403 ℃.
-Solubility: DINP is soluble in most organic solvents.
Use:
-Plastic additives: DINP is a commonly used plasticizer that can be used for polyvinyl chloride (PVC) and other plastics to improve its flexibility, ductility and heat resistance.
-Coatings and inks: DINP can be used as a soluble plasticizer for coatings and inks to provide flexibility and durability of the coating.
-Medical products: DINP can be used to manufacture flexible plastic products such as medical equipment and infusion bags.
-Other uses: DINP can also be used for synthetic rubber, tape, waterproof materials, etc.
Preparation Method:
The preparation of DINP is usually carried out by transesterification. A common method of preparation is to react styrene and a di-C8-10-alkyl ester of phthalic acid in the presence of a catalyst to form DINP. The preparation process needs to be properly controlled to ensure the purity and quality of the product.
Safety Information:
-Toxicity: DINP has less impact on human health at general use and expected concentrations. However, long-term or high-concentration exposure may have some potential toxicity to the reproductive system and liver.
-Carcinogenicity: According to relevant research, DINP has not been confirmed as carcinogenic at present.
-Environmental impact: DINP is difficult to degrade in the environment and may have certain toxic effects on aquatic organisms. Therefore, it is necessary to pay attention to environmental protection when using and handling DINP.
Important note: The above information is for reference only. Please be sure to follow the safety technical instructions and relevant regulations of the specific product when using DINP or related compounds.
