Phthalic Anhydride | S&P Global - IHS Markit
The largest markets for phthalic anhydride are phthalate plasticizers, unsaturated polyester resins, and alkyd resins for surface coatings. Commercial phthalic anhydride is 99.8–99.9% pure (99.5% is generally guaranteed) and is available in two forms—flake and molten. Most worldwide consumption of phthalic anhydride is molten.
Production of phthalic anhydride from biorenewables: process
Phthalic anhydride (PA) has a key importance in the production of plasticizers, polyesters and resins. Its production is based on fossil feedstocks and is expected to grow up to 5 Mt per year by 2018, as such its market would be affected by petroleum depletion concerns.
Transforming Sugarcane Bagasse into Bioplastics via
The major challenges for directly converting lignocellulosic biomass into available materials in place of synthetic polymer materials are the complex chemical–physical structure and the narrow processing windows of the resources. In the present study, homogeneous chemical modification of sugarcane bagasse with phthalic anhydride was taken to be an improved strategy to meet the challenges. FT
Phthalic anhydride
Phthalic anhydride is a principal commercial form of phthalic acid. It was the first anhydride of a dicarboxylic acid to be used commercially. This white solid is an important industrial chemical, especially for the large-scale production of plasticizers for plastics.
- What is plasticizer production phthalic anhydride?
- Plasticizer Production Phthalic anhydride is a primary raw material for producing phthalate esters, which are used as plasticizers in flexible PVC and other polymers. These plasticizers improve the flexibility, durability, and elasticity of plastic products.
- What is phthalic anhydride?
- Phthalic Anhydride is an essential intermediate used in the production of plasticizers, alkyd resins, and unsaturated polyester resins. Its ability to enhance the flexibility, durability, and performance of plastics, resins, and coatings makes it a critical component in a wide range of industrial and consumer products.
- How is phthalic anhydride prepared?
- Phthalic anhydride can also be prepared from phthalic acid by simple thermal dehydration above 210°C. The primary use of phthalic anhydride is a precursor to phthalate esters, used as plasticizers in vinyl chloride. Phthalate esters are derived from phthalic anhydride by the alcoholysis reaction.
- How are phthalate esters derived from phthalic anhydride?
- Phthalate esters are derived from phthalic anhydride by the alcoholysis reaction. In the 1980s, approximately 6.5 million tonnes of these esters were produced annually, and the scale of production was increasing each year, all from phthalic anhydride.
- What are the benefits of phthalic anhydride?
- One of the primary benefits of Phthalic Anhydride is its ability to enhance the flexibility and durability of plastic products. When used in plasticizers, it allows materials like PVC to maintain flexibility even at low temperatures, ensuring that products such as cables, hoses, and floorings are both pliable and long-lasting. 2.
- Why is phthalic anhydride a versatile intermediate in organic chemistry?
- Phthalic anhydride is a versatile intermediate in organic chemistry, in part because it is bifunctional and cheaply available. Hydrolysis by hot water forms ortho -phthalic acid: Hydrolysis of anhydrides is not typically a reversible process. Phthalic acid is however easily dehydrated to form phthalic anhydride.
