天津是我国现代化学工业发源地之一。1921年,实业家范旭东和归国博士侯德榜在塘沽兴建了亚洲第一座苏尔维法制碱厂(即天津碱厂前身永利制碱厂),从此开创了天津现代化学工业纪元。经过80多年,特别是建国及改革开放以来的快速发展,天津化学原料及化学制品制造业(以下简称:化学原料、制品业)在全国地位不断增强。在天津化学原料、制品业中,低盐重质纯碱、聚氯乙烯、苯酐、顺酐、炭黑、涂料和气体等行业及产品在规模与技术上处于国内领先水平。聚氯乙烯生产品种国内名列前茅,
Tianjin is one of the birthplaces of modern chemical industry in China. In 1921, Fan Xudong, an industrialist, and Hou Debang, a returning country doctor, built the first Sulawesi soda plant in Asia (Tianjin Soda Plant’s predecessor, Yongli Soda Plant) in Tanggu, and thus created the era of Tianjin’s modern chemical industry. After more than 80 years, especially since the founding of the People’s Republic of China and the rapid development since the reform and opening up, Tianjin’s chemical raw materials and chemical products manufacturing industry (hereinafter referred to as: chemical raw materials, product industries) has continued to strengthen its position in the country. In the chemical raw materials and products industry in Tianjin, industries and products such as low-salt soda ash, polyvinyl chloride, phthalic anhydride, maleic anhydride, carbon black, paint, and gas are at the leading domestic level in terms of scale and technology. PVC production ranks among the best in the country.
