Isophthalic acid solubility
This chemical is soluble in water (120mg/L) and propanol, but it is not able to dissolve in benzene and ether. It is important to note that this chemical can’t mix with hot water.
Isophthalic acid uses
This chemical substance is used in the formulation of plastics, polymers, inks, and adhesives. The manufacturer also uses this substance in manufacturing PET plastics. In this part, we will explain the applications of this chemical in detail.
Making plastic and polyester
This chemical is widely used in plastic synthesis and it plays an important role in the plastics properties. Among all of the customers, 37% of this acid production is used in polyester resins.
· Alkyd coatings
These are some oil-based polyester coatings. Around 30% of this acid is used in the production of alkyd coatings.
· PET plastics
One of the most important applications of this acid is the manufacturing of PET plastics. The pet plastics themselves are used in food and beverage packaging.
It is also used in dental materials and also formulation of ink and adhesives.
Isophthalic acid vs. terephthalic acid
If we want to explain the difference between these two chemicals, in the first place, we should know more about terephthalic acid. This chemical appears as a white powder, and it can’t dissolve in water. This chemical is also used in the production of PET plastics.
The difference between isophthalic acid and terephthalic acid is their structure. Isophthalic acid consists of two carboxylic acid groups that are connected to one carbon atom. Terephthalic acid also contains two carboxylic acids; however, the carboxylic acids of this substance are connected to two different carbon atoms.
Isophthalic acid MSDS
This chemical substance shouldn’t contact with your eyes and skin. So, after handling this substance wash the contact area with water. this chemical substance is stable under normal conditions however it shouldn’t be kept near incompatible materials such as strong oxidizing agents and heat. If you accidentally ingest some of this chemical substance wash your mouth with water as soon as possible.
Conclusion
Isophthalic acid is a useful and important raw material in most industries, such as ink production and manufacturing PET plastics. This chemical can dissolve cold water, but we can’t dissolve it in hot water. One of the other uses of this chemical is in dental materials. However, you should pay attention to MSDS while working with this substance because if in contact with your skin and eyes, it can cause damage. Remember to wash your hands with plenty of water after handling this acid.
