Abstract

본 발명은 타우린 제조부산물을 물에 용해하고 산성화제 즉, 황산, 염산, 인산, 질산, 초산, 개미산 및 트리플루오로초산에서 선택된 무기 또는 유기산을 사용하여 pH0.7~1.5로 산성화시킨후, 발생되는 아황산가스를 양압 또는 음압하에 공기로 폭기시키고 유리시켜서, 금속수산화물의 용액에 흡수시켜서 중아황산의 금속염을 제조하는 방법이다.The present invention is produced by dissolving taurine by-products in water and acidifying to pH 0.7-1.5 using an acid or inorganic acid selected from sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, acetic acid, formic acid, and trifluoroacetic acid. It is a method of manufacturing the metal salt of bisulfite by aeration and liberation of the sulfurous acid gas by air under a positive pressure or a negative pressure to be absorbed in a solution of the metal hydroxide.
