synthesis of nylon?

Question

the preparation of nylon is caried out with two solvents that do not dissolve in each other with one starting material in each of the solvents. the reaction occurs at the interface of the two solvents. why is it carried out in this way? what would the result be if one solvent that dissolved both reagents were used instead?

Answer 1

if caprolactam underwent the first reaction step in place of N-acetylcaprolactam, the product would be a much less stable amine anion, as opposed to the more stable amide ion formed when N-acetylcaprolactam reacts

Answer 2

The idea of getting the reaction to happen at the interface is to be able to draw a thread of nylon out continuously. As this is done, it allows more unreacted chemicals to come into contact with each other. If just one solvent was used, you would end up with a beaker containing one lump of solid nylon!

Answer 3

If both regents were dissolved in one solvent the polymerisation will simply crash out of solution. Where an interface happens the polymer can be slowly spin out of solution making it easier to collect, while it is being withdrawn from the solution the interface (if it is done slowly) will react with flesh regents and hence it will be an ongoing procss

Answer 4

So that the ensuing polymerisation does not disrupt the mixing.
