风化煤腐植酸增效尿素红外光谱分析
The Infrared Spectrum Analysis on Compound Urea with Humic Acid Extracted from Weathered Coal
摘要
Abstract
After treated with alkaline solution and then centrifuged, weathered coal was divided into water-soluble humic acid and deposi-tion. Then as the urea synergist materials, weathering coal, humic acid and deposition were respectively mixed with melted urea according to different proportion to produce three kinds of compound urea. The infrared spectrum analysis(IR)of above synergist materials and products found that after being treated with alkaline, weathered coal was reduced carbon-carbon bond amount and its carbon chain became shorten, more active functional group happened to the HA extracts. While the FR deposition showed carbon-carbon bond reduced and parts of amine or amide structure were formed. Additionally, the IR also found that during the compound of urea with the synergists, the formation of carbon-carbon triple bond, the broken of accumulated double bonds, the shorten of carbon chain, and the formation of more double bond and stable structure were observed. However, the different synergists mixed with urea brought out different IR characters.关键词
