Phthalic Anhydride derived Polyesters and Nylon structures+reactions?

  • Thread starter ptpatil
  • Start date
In summary, the lab for Materials Science for Engineers explores the synthesis of polyesters and nylon. Phthalic anhydride and ethylene glycol are used to create a polyester, while glycerin and ethylene glycol are used to create a different polyester. Nylon is then formed from sebacoyl chloride and hexamethylenediamine. The chemistry behind these reactions is not taught, but it is assumed that the OH groups in the molecules react with each other. The specific structures of the resulting polyesters and nylon-6,10 are unknown.

Phthalic Anhydride derived Polyesters and Nylon structures+reactions?

Homework Statement


Im doing a lab for Materials science for engineers.
they want to know how phthalic anhydride and ethylene glycol makes a polyester. They also want to know how that and glycerin make a polyester.

After that we made nylon from sebacoyl chloride and hexamethylenediamine.

Im a first year student and I have no clue how these reactions work, they didnt teach us about the chemistry just the mechanical properties once the polymer chains are formed.

Homework Equations

The Attempt at a Solution



I figured that the OHs would probably react with each other on the ends of the molecule but I have no idea what the polyester structure would be of the either the phthalic anhydride derived polyesters or the nylon-6,10.

I do know that there are probably two reactions from the ethylene glycol with the oxygens in the phthalic anhydride but nothing further than that.

Related to Phthalic Anhydride derived Polyesters and Nylon structures+reactions?

1. What are Phthalic Anhydride derived Polyesters and Nylon structures?

Phthalic Anhydride derived Polyesters and Nylon structures are types of synthetic polymers that are produced by the reaction of Phthalic Anhydride with various alcohols and amines, respectively. These structures are commonly used in the production of plastics, fibers, and resins.

2. How are Phthalic Anhydride derived Polyesters and Nylon structures formed?

Phthalic Anhydride derived Polyesters are formed through a condensation reaction between Phthalic Anhydride and a diol, such as ethylene glycol. This reaction results in the formation of an ester bond, linking the Phthalic Anhydride units together. Nylon structures, on the other hand, are formed through a polycondensation reaction between Phthalic Anhydride and a diamine, such as hexamethylenediamine, resulting in an amide bond.

3. What are the properties of Phthalic Anhydride derived Polyesters and Nylon structures?

Phthalic Anhydride derived Polyesters are known for their high strength, durability, and resistance to chemicals and heat. They are also lightweight and have good electrical insulation properties. Nylon structures are also strong and durable, with good resistance to abrasion and chemicals. They are also known for their high melting point and low moisture absorption.

4. What are some common applications of Phthalic Anhydride derived Polyesters and Nylon structures?

Phthalic Anhydride derived Polyesters are commonly used in the production of plastics, fibers, and resins, which are then used in a variety of applications such as packaging, textiles, and automotive parts. Nylon structures are also used in the production of fibers and plastics, as well as in the manufacturing of products such as ropes, carpets, and toothbrush bristles.

5. What are some important reactions involving Phthalic Anhydride derived Polyesters and Nylon structures?

One important reaction involving Phthalic Anhydride derived Polyesters is the hydrolysis reaction, which breaks down the ester bonds and results in the formation of carboxylic acids. This reaction is commonly used in the recycling of polyester products. For Nylon structures, one important reaction is the condensation polymerization, which involves the formation of amide bonds between the Phthalic Anhydride and diamine monomers, resulting in the formation of long chains of Nylon. Other reactions involving these structures include oxidation, reduction, and esterification reactions.
