| 内容記述 | Tetramethylammonium hydroxide is used in various electric and electronic parts production processes, such as those for making semiconductors, liquid crystal displays and printed circuit boards. The discharged amount of this chemical reaches about 2,500 ton/year from one factory in Japan. The waste liquor discharged from the liquid crystal display production contains 0.53 wt% tetramethylammonium hydroxide, 60 mg/d3 phenol and a ppb order of metal ions. In the cation exchange reaction, tetramethylammonium ion is captured on the cation exchange resin. Other non-ionic organic matter, such as phenol, goes through the resin without being captured on it, the separation being attained in this step. In the elution step, tetramethylammonium ion captured on the resin is released as tetramethylammonium chloride into aqueous solution by the action of dilute hydrochloric acid. Tetramethylammonium chloride is converted to tetramethylammonium hydroxide by the reaction between tetramethylammonium chloride and OH type anion exchange resin. The process is composed of three steps, that is，cation exchange, elution and conversion. The experiments were carried out using an ion exchange resin column of 20 mmφ and 735 mm height, in order to investigate the recovery and purity of percents tetramethylammonium hydroxide at each step. |
