(±)-1,2-Benzenedicarboxylic acid mono(1-methylheptyl) ester - Introduction
(±)-2-octyl hydrogen phthalate, also known as dioctanoate anhydride, is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
(±)-2-octyl hydrogen is a colorless to slightly yellow liquid. It has a property of being hardly soluble in water, but soluble in organic solvents such as ethanol, ethers and esters. It has a relatively low density, a melting point of about -60°C and a boiling point of about 400°C.
Use:
(±)-2-octyl hydrogen is commonly used as a plasticizer and plasticizer. It can be added to polymers to increase the plasticity, ductility and cold resistance of plastics. In addition, it is also used as a plasticizer in the paint, adhesive, rubber, ink and other industries to improve the softness and plasticity of the product.
Preparation Method:
(±)-2-octyl hydrogen can be prepared by the reaction of phthalic acid and 1-octanol. First, phthalic acid and 1-octanol form (±)-2-octyl benzene-1,2-dicarboxylate by esterification. The Ester is then hydrogenated to (±)-2-octyl hydrogen phthalate by reductive decarboxylation.
Safety Information:
(±)-2-octyl hydrogen phthalate is generally safe under normal conditions of use. However, it may be irritating to the skin and eyes, and should be rinsed with water immediately after contact. In addition, long-term exposure to high concentrations of (±)-2-octyl hydrogen phthalate may cause problems with the respiratory and digestive systems. Therefore, in the use of the process should comply with the relevant safety procedures, and take appropriate protective measures.
