Reaction Conditions:

in cyclohexane at 50 - 75;

Steps:

1 Bis[2-(2-isopropyloxazolidin-3-ethyl)]carbonatepreparation method

The bisoxazolidine latent curing agent is prepared by the transesterification reaction of dimethyl carbonate and 2-isopropyl-3-hydroxyethyl-1,3-oxazolidine, and belongs to the general formula (Ia) in claim 1 One of the compounds, its specific preparation method is as follows:Add 140g of diethanolamine and 120g of cyclohexane into a three-necked flask, stir evenly and heat to 50°C, slowly add 108g of isobutyraldehyde dropwise, and keep warm for 1 hour after the addition; when the temperature of the feed liquid rises to 75°C, it starts to reflux Divide the water, finish the water division after 4 hours, and distill the cyclohexane under negative pressure after the feed liquid drops to room temperature; then carry out vacuum fractionation on the above feed liquid, and collect the fraction at 75°C under 100Pa vacuum to obtain 210g 2-isopropyl-3-hydroxyethyl-1,3-oxazolidine.
