为了提高腐植酸的质量及满足出口需要,中国科学院山西煤炭化学研究所进行了用风化煤为原料研制硝基腐植酸的工作。经过近二年的研究,于1982年10月15—16日在太原举行小试鉴定会,内容包括制备硝基腐植酸的原料煤选择及条件的考查、褐煤和风化煤原煤腐植酸和硝基腐植酸结构解析和比较,产品使用初步效果以及原料及产品分析方法。该项目是由化工部下达的,正在太原化肥厂进行中间试验。
In order to improve the quality of humic acid and meet the needs of export, Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences conducted a study using weathered coal nitro-humic acid. After nearly two years of research, held in Taiyuan in October 15-16, 1982 small test appraisal, including preparation of nitrous humic acid raw coal selection and conditions of the test, lignite and weathered coal raw coal humic acid and nitro Humic acid structure analysis and comparison, the initial use of products and raw materials and product analysis. The project is issued by the Ministry of Chemical Industry, is in the middle of Taiyuan Fertilizer Plant test.
