腐殖酸中的有机物在铝酸钠溶液高压溶出过程中的形态变化
Morphology Change of Organics in Humic Acid During High Pressure Dissolution of Sodium Aluminate Solution
摘要
Abstract
The morphology change of organics in humic acid during Bayer alumina′s production process was studied .Adding humic acid into sodium aluminate solution then circulation dissolving at high pressure ,the morphology and its transformation rule of organics in humic acid in the process of each circulatory was examined .The experimental results show that the morphology of organics in humic acid is complex .Through 10 times circulation dissolution at high pressure ,the organics stable existing in leaching solution are butanoic acid ,butanoic acid butyl ester ,hexadecanoic acid butyl ester , octadecanoic acid butyl ester ,2‐methyl‐propanoic acid butyl ester , n‐Propyl 9‐octadecenoate , heneicosane and tetracosane .The result can be refer to removal organics during dissolving of bauxite at high pressure .关键词
