Nylon 5-12 Structure Drawing Tutorial

Click For Summary
SUMMARY

The discussion focuses on the structure of Nylon 5-12, specifically the confusion surrounding its chemical components. Nylon 5-12 is synthesized using 1,5-pentanediamine (cadaverine) and a specific dicarboxylic acid. Participants recommend revisiting the Wikipedia article on Nylon for clarity on the nomenclature and structure. Additionally, they highlight the importance of understanding the differences between related nylons, such as Nylon 6-10 and Nylon 4-10, which utilize different diamines.

PREREQUISITES
  • Understanding of polyamide chemistry
  • Familiarity with chemical nomenclature
  • Knowledge of diamines and dicarboxylic acids
  • Basic grasp of polymerization processes
NEXT STEPS
  • Research the chemical structure of Nylon 5-12 and its components
  • Study the polymerization process of polyamides
  • Explore the properties and applications of Nylon 5-12
  • Learn about the synthesis and characteristics of related nylons, such as Nylon 6-10 and Nylon 4-10
USEFUL FOR

Chemistry students, polymer scientists, and professionals in materials science who are interested in the synthesis and properties of polyamides.

Hello,

Can anyone tell me how to draw the structure of nylon 5-12 or what site could help me with this?

Thank you!

Hi Borek,

I did googled and Wiki nylon 5-12, I found the structure for nylon 6-10 and it has pentamethylene diamine and sebacic acid, but I'm confused about both to even know what should be added or removed for nylon 5-12.

Thanks.
 
So you have to reread wiki article, as it precisely and unambiguously explains what these numbers mean.
 
Man, I'd hate to be working in a plant that makes 5-10! The diamine, 1,5-pentanediamine, is also known as cadaverine. Cadaverine is a decomposition product of proteins (and Nylon 5-10, BTW) and smells like cadaver or Casey Anthony's trunk!

Probably not as bad as Nylon 4-10 though. It's diamine is 1,4-butanediamine and is known as putrescine, also derived from the decomposition of proteins and nylon 4-XX.
 

Thread 'Gold hydride - what is the significance?'

I came.across a headline and read some of the article, so I was curious. Scientists discover that gold is a 'reactive metal' by accidentally creating a new material in the lab https://www.earth.com/news/discovery-that-gold-is-reactive-metal-by-creating-gold-hydride-in-lab-experiment/ From SLAC - A SLAC team unexpectedly formed gold hydride in an experiment that could pave the way for studying materials under extreme conditions like those found inside certain planets and stars undergoing...
