A new catalyst for synthesizing n butyl lactate& Composite solid acid NH_4Fe ( SO_4)_2/ C 合成乳酸正丁酯的新型催化剂&固体酸NH4Fe(SO4)2/C
N-Butyl Lactate was synthesized from Lactic acid and n-butyl alcohol in the presence of sodium sulfate monohydrate. 在一水硫酸氢钠存在下,从乳酸和正丁醇能合成乳酸正丁酯。
When catalyzing and synthesizing n butyl lactate we often can't get ideal products if concentrated sulphuric acid is used as catalyst. This paper reports the research in which concentrated sulphuric acid is substituted by composite solid acid NH 4Fe ( SO 4) 2/ C. 在催化合成乳酸正丁酯时,用浓硫酸作催化剂得到的产品质量不理想,因此本文以自制的固体酸NH4Fe(SO4)2/C取代浓硫酸作催化剂进行研究。
