Laboratory grade of adipoyl chloride has a cloudy appearance. A trace amount of a white solid may be present—it will not interfere with the nylon polymerization reaction. Adipoyl chloride stores very poorly. Avoid buying large quantities. If you are planning to use this material for synthesis of nylon, you need only approximately 5 grams. Consider buying a ready-made adipoyl chloride/hexane solution, Flinn Catalog No. A0185.
Both sizes are packaged in PVC-coated bottles and then in a metal can for safer storage.
