【摘要】 硫酸酯是一类含有-OSO₃H基团的有机化合物。它在大气中普遍存在。异戊二烯、单萜、倍半萜、芳烃、醛等均可通过大气自由基反应或非均相反应生成硫酸酯。本文在充分研读已有文献的基础上,总结探讨硫酸酯的分子结构、形成机制、分析方法以及硫酸酯对气溶胶有机物的贡献。最后,对未来研究的热点方向加以展望。更多还原

【Abstract】 Organosulfate is a widespread atmospheric organic matter type containing-OSO₃H group. It can be formed from a variety of precursors including isoprene, monoterpenes, sesquiterpenes, aromatics and aldehydes,etc., via atmospheric radical reactions and heterogeneous reactions. This work summarizes the up-to-date knowledge on structures, formation mechanisms and analytical methods of organosulfates. The contributions of organosulfates to aerosol organic matters was discussed also. Future research needs on organosulfates were presented in the end of this article.更多还原
