Disclosed is a process for the regioselective preparation of glycerol derivative in a high efficiency and yield. The process for the regioselective preparation of 1-R
1
-2-R
2
-3-acetyl-glycerol derivative comprises the steps of: obtaining 1-R
1
-3-protecting group-glycerol by introducing a protecting group to 3-position of 1-R
1
-glycerol; obtaining 1-R
1
-2-R
2
-3-protecting group-glycerol by introducing R
2
group into 2-position of 1-R
1
-3-protecting group-glycerol; and carrying out the deprotection reaction and the acetylation reaction of 1-R
1
-2-R
2
-3-protecting group-glycerol at the same time. Wherein, R
1
and R
2
are fatty acid groups having 16 to 22 carbon atoms, and are different from each other; and the protecting group is trityl group or trialkylsilyl group.
