[tony]

How does one distinguish Nylon 6 from Nylon 66 using a simple chemical test?

can i use hydrolyssi in the presetn of acidic medium, and heat to dissolves all the strands of nylon.

thereafter upon cooling i expect nylon 66 to provide precipitate since it hexanediamine and hexandioic acid are less soluble in water while zwitterion of aminohexanoic aicd molecule would be completely soluble
