Jiang, Feng; Gao, Donghui; Feng, Xi; Pan, Jiaming; Pu, Wanfen published an article in 2021. The article was titled 《W/O high internal phase emulsions (HIPEs) stabilized by a piperazinyl based emulsifier》, and you may find the article in Soft Matter.Recommanded Product: 1-Methylpiperazine The information in the text is summarized as follows:
In this study, a piperazinyl-based emulsifier (EA/AMPA) was synthesized to prepare water-in-oil (W/O) high internal phase emulsions (HIPEs). Using kerosene as the oil phase, stable HIPEs with internal phase fractions of up to 98% were prepared This enabled the EA/AMPA to have a high efficiency, as the HIPEs with a 90% internal phase fraction could be easily prepared with 0.1% of EA/AMPA. In addition, the formation of HIPEs was not affected by the addition of Na+. Because of the fact that EA/AMPA has a hydrophilic head with two tertiary amines, EA/AMPA could be easily recovered from the oil phase by adjusting the pH to acidic values. Moreover, the unique structure promoted the formation of stable HIPEs, even with crude oil used as the oil phase. The results indicate that EA/AMPA has the potential to significantly contribute to the preparation of W/O HIPEs and that the design of the hydrophilic head with two tertiary amines can provide a reference for the fabrication of new W/O emulsifiers. After reading the article, we found that the author used 1-Methylpiperazine(cas: 109-01-3Recommanded Product: 1-Methylpiperazine)
1-Methylpiperazine(cas: 109-01-3) can be used as mimic template in the preparation of molecularly imprinted microspheres (MIMs). It was also used to prepare the difunctional strong anion-exchange stationary phase from a 1,4-diazacyclohexane derivative..Recommanded Product: 1-Methylpiperazine
