硫酸是化学工业不可缺少的原料 ,也是生产磷肥的重要原料之一。我国硫酸工业以建国初期年总产量４万吨为基础 ,保持较高的年增长速度 ,至１９９８年 ,我国硫酸产量达２１７１万吨 ,仅次于美国 ,居世界第二位。产量的大幅度增长和资源结构的根本改观是行业发展的显著成果 ,科技 Sulfuric acid is an indispensable raw material for the chemical industry and one of the important raw materials for the production of phosphate fertilizers. China’s sulfuric acid industry is based on the total annual output of 40,000 tons in the early days of the founding of the People’s Republic of China, and maintains a high annual growth rate. By 1998, China’s sulfuric acid production reached 21.71 million tons, second only to the United States, ranking second in the world. The dramatic increase in production and the fundamental change in the resource structure represent a significant achievement in the development of the industry.
