zelf nylon maken

Arjan1988

hallo,

ik zit in 6VWO en ben op zoek naar een manier om zelf nylon 6-6 te maken.

Als iemand mij daarmee zou kunnen helpen zou ik daar erg blij mee zijn.

Nylon 6,64. Prepare a 5% aqueous solution of hexamethylenediamine (1,6-hexanediamine). Pour 10 mL of that solution into a 50 mL beaker. Add 10 drops of 20% sodium hydroxide solution. Carefully add 10 mL of a 5% solution of adipoyl chloride (dissolved in cyclohexane solvent!) to the hexamethylenediamine by pouring it down the inside wall of the slightly tilted beaker. Two layers will form, and there will be an immediate formation of a polymer film at the liquid-liquid interface. Using a copper-wire hook (a 6-inch piece of wire bent at one end), gently free the walls of the beaker from the polymer strings. Then hook the mass at the center and slowly raise the wire so that polyamide forms continuously, producing a rope that can be drawn out for many feet. The strand can be broken by pulling it faster. Rinse the rope several times with water and lay it on a paper towel to dry. With the piece of wire, vigorously stir the remainder of the two-phase system to form additional polymer. Decant the liquid and wash the polymer thoroughly with water. Allow the polymer to dry. Do NOT discard the nylon in the sink. Use a waste container.
