  Biocidal activity and corrosion inhibition of some cationic surfactants derived from Thiol polyurethane.

  摘要：

  SIX series of cationic polyurethane surfactants [PQ10-20] were synthesized by the reaction between different six esters (which prepared by condensation of fatty alcohols namely: octanol, decanol, dodecanol, tetradecanol, hexadecanol and octadecanol with bromoacetic acid) and polyurethane as quaternizing agent. The chemical structures of these surfactants were confirmed using elemental analysis, FTIR spectra,+HNMR and UV analysis. The surface activities of the synthesized cationic thiol polyurethane surfactants showed their tendency towards adsorption at the air/water interface. The adsorption tendency was estimated from the values of surface tension and the depression of surface tension at the critical micelle concentration. The studied surfactants were evaluated as antimicrobial agents against pathogenic and sulfur reducing bacteria using inhibition zone diameters and minimum inhibition concentration values. The synthesized cationic thiol polyurethane surfactants showed good antimicrobial activities against the tested microorganisms including Gram positive, Gram negative as well as fungi. The synthesized compounds were tested for the activity as corrosion inhibitors against carbon steel corrosion in 2N H2SO4 at 50, 100, 200, 400 and 600 ppm. The inhibition efficiencies of the tested compounds showed good inhibition and protection of the carbon steel. The corrosion inhibition tendency correlated to the surface activity and chemical structure of the compounds.

  Disclosed is an enclosure for an external chemical, which comprises an enclosure body receiving the external chemical therein and having an opening for exposing the external chemical when used, a sealing film for allowing the external chemical to be sealingly enclosed in the external chemical, an adhesive layer provided at the peripheral portion of the opening of the enclosure body, and a releasable film releasably attached to the enclosure body by use of the adhesive layer. In this enclosure, after the releasable film is removed, the adhesive layer serves as an adhesive portion for allowing the enclosure body to be attached to a diseased area. The enclosure of the present invention can reliably maintain the contact between the external chemical and the disease area in a simple structure.
