TEREPHTHALIC ACID DISODIUM SALT - Introduction
The disodium salt of terephthalic acid, the chemical formula is Na2C6H4(COONa)2, also known as disodium phthalate or disodium dicarboxylate. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
1. terephthalic acid disodium salt is a colorless crystal, soluble in water and alcohol solvents.
2. It has a certain degree of stability and is not easy to decompose under appropriate conditions.
3. disodium terephthalate will decompose at high temperature and produce harmful gas.
Use:
1. Terephthalic acid disodium salt is often used in industry as a dye and mordant.
2. It is also used as a fixing agent for fibers, leather and paper.
3. The disodium salt of terephthalic acid can also be used to prepare other organic compounds, such as softeners and fluorescent whitening agents.
Preparation Method:
The disodium salt of terephthalic acid is usually prepared by reacting terephthalic acid with sodium hydroxide. The specific step is to first dissolve terephthalic acid and an appropriate amount of sodium hydroxide in a solvent, then heat react for a period of time, and finally cool and crystallize to obtain a product.
Safety Information:
1. Terephthalic acid disodium salt is generally safe under conventional use conditions, but avoid inhalation of dust and contact with the skin and eyes.
2. Appropriate personal protective measures, such as gloves, safety glasses and respiratory protective equipment, should be taken when handling the compound.
3. Terephthalic acid disodium salt should be stored in a dry, cool place, away from fire and oxidant.
Please note that the above information is for reference only. The specific operation and use should follow the laboratory safety operation procedures and relevant regulations.
