Abstract
HSt 3, NaOH and FeCl 3 were used to synthesize Ferric stearate by the method of double decomposition reaction and the best conditions of the ferric stearate were characterized by ICP, IR and UV. The results showed that when molar ratio of HSt 3/ NaOH/FeCl 3 reached 3/3 18/1 08, and the weight ratio of HSt 3/ H 2O was 1/20, the production FeSt3 was the most pure. There were two absorption peaks at 222 nm and 265 nm in the production UV spectrum, so it was an effective photosensitizer for degradable mulch film.
