L-天门冬氨基酸钼螯合物的合成研究

Preparation on chelate of aspartic acid molybdenum

以L -天门冬氨基酸为原料合成制备L -天门冬氨基酸钼螯合物 ,运用正交设计实验对影响L -天门冬氨基酸螯合钼的条件进行研究 ,获得最佳反应条件 :n(L -天门冬氨基酸 ) :n(MoO3 ) =5 .5 :1,反应温度T =75℃ ,反应酸度pH =8.0 ,反应时间t=2h。通过络合滴定 ,凯氏定氮法 ,红外光谱对产品进行分析确认。

The thesis introduced the procedure of synthesizing L-aspartic acid molybdenum complex with the raw material of L-aspartic acid.Based on orthogonal experiment we get the best conditions of reaction:n(L-aspartic acid ):n(MoO_3)=5.5:1,That,s reaction temperature is 75℃,reaction solution,s acidity is 8.0,reaction time is 2h. Also the product was analyzed and confirmation with IR and Kjeldahl determination etc.
