application | the two nitrogen ends of 1,2-dimethylpiperazine are easy to chemically react with other functional groups, and the amine hydrogen of 1,2-dimethylpiperazine is substituted by long-chain alkyl or alkoxy derivatives, which can be used as wetting agents, emulsifiers, dispersants and cleaning agents. For example, 1, 2-dimethylpiperazine and mono-esters of various fatty acids can be used as additives to improve the hard water resistance of fatty acid soap; mono-esters and mono-ethers of 1, 2-dimethylpiperazine can be used as emulsifiers for emollients. |
