The general procedure for the synthesis of N,N'-bis(2-hydroxyethyl)piperazine from diethanolamine is as follows: Example 2: Preparation of 1,4-bis(hydroxyethyl)piperazine from diethanolamine under solvent-free conditions Operational steps: 1. 100 g of diethanolamine (II) and 10 g of Catalyst A were added in the same reaction setup described in Example 1 . 2. Upon completion of the reaction, the reaction product was detected by gas chromatography analysis (GC column: 30m RTX Amin). 3. The analytical results showed that the content of 1,4-bis(hydroxyethyl)piperazine in the reaction product was 79% under the condition of complete conversion of diethanolamine.

Example 2Preparation of 1,4-bis(hydroxyethyl)piperazine from diethanolamine (no solvent)Example 2 was carried out under the conditions of example 1 in the same apparatus. 100 g of diethanolamine (II) and 10 g of catalyst A were used. Gas chromatographic analysis (GC column: 30 m RTX Amin) indicated, at quantitative diethanolamine conversion, that the reaction output comprised 79% of 1,4-bis(hydroxyethyl)piperazine.
