Hexamethylene diisocyanate → HCID 19390273, compound

Participants

Reaction Steps

1,6-Hexyl Urea Styrene Dimer: 1.00 g (8.40 mmol) of p-aminostyrene (99% Tokyo Kasei) was added to a 250 ml round bottom flask containing 100 ml of chloroform. After ten minutes of mixing, 0.706 g (4.20 mmol) of 1,6-diisocyanato hexane (98% Aldrich) was added dropwise. After twenty minutes, a white, pinkish precipitate formed. The precipitate was filtered to remove the reaction liquid, then washed with 20 ml of chloroform resulting in a pale white powder (0.87 g, 51% crude yield, mp=228° C.).
