PROCEDURE
实验过程
The exact procedure described above (high dilution and dropwise addition) was repeated for 26.0 g of the aldehyde (VI), 110 g of sodium bisulfite, and 30.0 g of the tetramine (V) in a total volume of 4.5 L of 1:5 water-ethanol. At the end, the powdery end product (VIII) was fractionated by Soxhlet extraction into an ether-insoluble portion (high oligomers) and an ether-soluble portion (20.0 g, 46.9%). The latter material, when tested on the Kofler hot bench at 250° C., showed a gel time of about 3 minutes.
