Density estimated physicochemical properties of alanine-based ionic liquid [C7mim][Ala] and its application in selective transesterification of soybean oil

Amino acid ionic liquid （AAIL） based on alanine, 1-n-heptyl-3-methylimidazolium alanine （[C7mim][Ala]）, has been prepared and characterized. Since the IL can form strong hydrogen bonds with water, trace amount of water is a problematic impurity in the IL. Using the standard addition method （SAM）, th...
