A new cationic gemini surfmer: Synthesis and surface activities

A new cationic gemini surfmer (polymerizable surfactant or surface-active monomer) with an acrylic reactive group in its spacer group was synthesized and characterized, and its surface activity properties were examined in comparison with its intermediate surfactant 12-3OH-12?2Cl-, a previously-reported gemini surfmer 12′-2-12′?2Br-, as well as monomeric surfactant dodecyl trimethylammonium bromide. It was found that neither the incorporation of a double bond onto the gemini surfactant nor the change of location of the double bond will affect surface activities of the gemini surfactant.

Acrylic acid biquaternary ammonium salt monomer and preparation method thereof

The invention belongs to the technical field of biquaternary ammonium salt. The invention particularly relates to an acrylic acid biquaternary ammonium salt monomer and a preparation method thereof. The structural general formula of the acrylic acid biquaternary ammonium salt monomer is shown in Figure 3, and the preparation method of the acrylic acid biquaternary ammonium salt monomer comprises the following steps: (1) dissolving a raw material I and a raw material II in a first organic solvent, adding a catalyst, reacting at 60-90 DEG C for 24-72 hours, and purifying to obtain an intermediate product 1; wherein the molar ratio of the raw material I to the raw material II is 1.0: (2.0-3.6); and (2) dissolving the intermediate product 1 into a second organic solvent, adding a neutralizer and a raw material III, reacting at 0-50 DEG C for 6-36 hours, and purifying to obtain an acrylic acid biquaternary ammonium salt monomer;; wherein the molar ratio of the intermediate product 1 to theraw material III to the neutralizer is 1.0: (1.0-1.5): (1.0-1.5), and the acrylic acid biquaternary ammonium salt monomer has good surface activity and antibacterial property.

Oligomeric quaternary ammonium salt bactericide and preparation method thereof

The invention relates to an oligomeric quaternary ammonium salt bactericide and a preparation method thereof. Ester p-toluenesulfonate-based gemini quaternary ammonium salt, guanidine hydrochloride and sodium alkoxide are added into solvent, stirred and heated to 120 DEG C to 180 DEG C, heating is stopped after 10 to 48 hours of reaction, so that a crude product is obtained, and after post-treatment, the oligomeric quaternary ammonium salt bactericide is obtained; and the substance amount ratio of the ester p-toluenesulfonate-based gemini quaternary ammonium salt, the guanidine hydrochloride and the sodium alkoxide is (0.008 to 0.040):0.008:0.008. The gemini quaternary ammonium salt is introduced to a plurality of active sites, eight active sites are contained in the structure of the oligomeric quaternary ammonium salt bactericide, the oligomeric quaternary ammonium salt bactericide can show good water solubility and surface activity in aqueous solution, and an important role is played in the process of oligomeric quaternary ammonium salt preparation. A bacteria killing test on three types of bacteria, i.e. sulfate reducing bacteria, iron bacteria and saprophytic bacteria, indicates that the oligomeric quaternary ammonium salt bactericide has a good bactericidal effect.
