Phthalic anhydride uses are very widespread in various industries. This substance, which has a white color, is very dangerous! This material is one of the most important materials used to synthesize plasticizers. Naturally, phthalic anhydride is present in liquid form.

It is also non-volatile and a very toxic substance. With the advancement of technology, phthalic anhydride uses have become more diverse. This material is used to make various plastics. In addition, phthalic anhydride is used to increase the flexibility of various plastics. In the rest of this PetroProviders article, join us to introduce you to phthalic anhydride uses.

How is phthalic anhydride made?

What is PA

What is PA

The chemical reaction of this material is done using naphthalene or O-Xylene. This substance is a kind of acid and is considered an aromatic compound. Due to its white color combination, this material is also used to produce different colors.

In general, there are two types of appearance for phthalic anhydride. Clear, colorless liquid or white powder. This substance has a very pungent odor and can be detected by inhalation. This substance is very toxic and in contact with the skin, it causes skin eczema.

Phthalic anhydride was first produced in Germany. It was formed by the oxidation of naphthalene. The phthalic anhydride produced was a liquid and a mercury catalyst was used in the production reaction. In general, this material was not of good quality!

Phthalic anhydride is available in both liquid and powder forms. It dissolves easily in alcohol or disulfide solution. Next, we look at phthalic anhydride uses.

phthalic anhydride uses in the world

Phthalic anhydride is a very widely used substance in industry. This material can be easily combined with other materials to make very valuable materials. Here are three very important uses of phthalic anhydride.

Making unsaturated polyester resin

Unsaturated polyester resins can be made using phthalic anhydride. This material is resistant to heat and after melting, it changes into different shapes. This is one of the most popular resins in the world. In addition, the constituent chain of these polyesters is a long ester chain formed after the reaction of anhydrides with acids.

Making alkyd resin

Another phthalic anhydride use is the production of alkyd resins. These resins are the oldest and cheapest resins. Once made, these resins are resistant to water and sunlight but are reactive to acid.

This material is easily used for coloring products. Even if the surface is not clean, alkyd resins can be used for painting. It is resistant to acid spraying. It should be noted that this acid, if strong, causes damage to the paint. Therefore, it is not very resistant to acids. So it can not be used in the presence of strong oxidants or alkalis.

Reactions of anhydrides are used to make alkyd resins. For example: isophthalic, maleic anhydride and phthalic anhydride. These materials combine with glycerin and increase the strength and quality of alkyd resins.

Manufacture of plasticizers

One of the uses of phthalic anhydride is to make plasticizers. These materials combine with phthalic anhydride to make them very flexible. In addition, this material is one of the most widely used materials in the manufacture of PVC materials. It is very cheap and has various applications in the plastics industry.

Due to the unique properties of these materials, their various applications in industry are predictable.

In this article from PetroProviders, we looked at phthalic anhydride uses. This substance is also used in the manufacture of medical products. It is used to make cellulose phthalate (CAP) acetate. This material is used as a suitable coating for the intestines. It should be noted that direct contact with phthalic anhydride can cause severe damage to your lungs and skin.

This material is used to make paints and colored insulations. In addition, phthalic anhydride is known as an antiviral agent. By using this material in coating products, the fire resistance of products increases.

Another phthalic anhydride uses is the production of yellow quinoline dye. The production reaction of this dye is the combination of phthalic anhydride with methyl quinoline. This reaction takes place in a completely safe environment; Therefore, to ensure the safety of the reaction, be sure to avoid direct contact with phthalic anhydride.

This material is widely used in various industries. It can be used to produce different colors. Also, phthalic anhydride is very valuable for chemical reactions.
