関与物質

反応手順

An alkaline solution of 4 g of sodium stearate in 100 ml of water is metered into a suspension of 100 g of Iriodin 300 (TiO2 /Fe2O3, mica having a particle size of 10-60 μm from E. Merck, Darmstadt) in 1000 ml of water at a pH of 6, resulting in the precipitation of stearic acid while keeping the pH constant with 5% hydrochloric acid. The product is then filtered off, dried and pyrolysed at 800° C. in an N2 gas stream.
