68515-40-2 - Introduction
1,2-benzenedicarboxylic acid, benzyl C7-9-branched and linear alkyl esters, also known as DINP, is a common plastic additive. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: DINP is a colorless to pale yellow liquid.
-Density: about 0.97g/cm³.
-Melting point: About -50 ° C.
-Boiling point: About 386 ° C.
-Solubility: DINP soluble in organic solvents, insoluble in water.
Use:
-Plasticizer: DINP is a commonly used plasticizer, added in the manufacturing process of polyvinyl chloride (PVC) to improve the flexibility and processability of PVC.
-Coatings and inks: DINP is also used as a plasticizing agent for oil-based coatings and inks to provide better adhesion and extensibility.
-Printing and dyes: It can also be used as a solvent for printing pastes and dyes to provide good dispersibility and fluidity.
Preparation Method:
DINP is usually obtained by reacting phthalic acid (C6H4(COOH)2) with octanol (C8H17OH). The reaction is carried out under oxygen-deficient conditions and a catalyst, such as a tin salt, is used.
Safety Information:
- DINP is considered relatively safe under regular use, but at high concentrations or long-term exposure, it may have a certain impact on human health.
- DINP is slightly irritating, avoid contact with skin and eyes. If inhaled or ingested, seek medical help immediately.
-For workers using DINP, appropriate protective measures should be taken, such as wearing gloves, glasses and protective clothing.
-According to relevant international standards and regulations, the use of DINP is subject to some restrictions, especially for children-related products and toys.
