| titleOfInvention | Improved process for making alkoxylated piperazine compounds |
| abstract | The present invention relates to an improved process for making mono- and di-alkoxylated piperazine compounds especially dihydroxyethylpiperazine. The improvement comprises the addition of an acid to the piperazine compound prior to the addition of an alkylene oxide to a reactor wherein the alkoxylated piperazine compound is prepared. Said improvement reduces the concentration of undesirable glycol ether byproducts which contribute undesirable color and foaming of the alkoxylated piperazine compounds. |
