Hydrochloric Acid → Ammonium 12-aminododecanoate

Participants

Reaction Steps

100 g of montmorillonite having an average thickness of the silicate layer unit of 0.95 nm and a size of about 0.1 μm was dispersed in 10 liter of water, to which 51.2 g of 12-aminododecanoic acid and 24 ml of a concentrated hydrochloric acid were added. The mixture was stirred for 5 minutes, and dried under vacuum to obtain a composite of ammonium 12-aminododecanoate ions and montmorillonite. The layer distance of the layered silicate particles (the weight center distance of the particles) in the obtained composite was measured by an X-ray diffraction to be 1.8 nm.
