Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-(2-heptadecyl-2-imidazolin-1-yl)ethanol is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Fire Hazard

Flash point data for 2-(2-heptadecyl-2-imidazolin-1-yl)ethanol are not available but 2-(2-heptadecyl-2-imidazolin-1-yl)ethanol is probably non-flammable.

Synthesis and properties of a series of CO2 switchable surfactants with imidazoline group

Switchable surfactants are environment-friendly compounds, which can be separated from the system or lose surface activity after completing their function during one stage of a process. In order to study switchable properties of a kind of CO2 switchable surfactant with an imidazoline group, four 2-alkyl-1-hydroxyethylimidazolines were synthesized by condensation of N-(2-hydroxyethyl)ethanediamine with dodecanoic, tetradecanoic, hexadecanoic, and octadecanoic acids. Then, the series of long-chain alkyl imidazoline compounds were reacted with dry ice to produce imidazolinium bicarbonates cationic surfactants. The critical micelle concentration (CMC) and surface tension at CMC (γcmc) measured by the Wilhelmy plate technique show that these surfactants have excellent surface activity. The changes of conductivity before and after bubbling CO2 show the conversion between imidazolines and imidazolinium bicarbonates cationic surfactants. Conductivity cycles indicated that these surfactants could be switched by CO2 reversibly and repeating this three times. However, their switchable function on the emulsification-demulsification of water-alkane was dissatisfactory due to the emulsibility of amide which was hydrolyzed from 2-alkyl-1-hydroxyethylimidazoline. Therefore, the application of these switchable surfactants needed to be studied further.

Synthesis of Long Chain 2-Alkyl-1-(2-hydroxyethyl)-2-imidazolines under Microwave in Solvent-Free Conditions

An efficient method for the synthesis of long chain 2-alkyl-1-(2-hydroxyethyl)-2-imidazolines, and their amide precursors, by condensing aminoethylethanolamine and several fatty acids under non-solvent microwave irradiation using CaO as support, is described. Products were obtained in good yields and high purity in a few minutes, in both multimode microwave and monomode microwave oven. Evidences of non-thermal microwave effects are given.
