  摘要：

  通过异硫酸钠、丙烷磺内酯和丁烷磺内酯与分别由 10、11 和 12 个碳原子组成的正常主脂肪酸制备了一系列磺烷基烷酸钠（RCOO(CH2)jSO3Na）。研究了酯基位置对这些表面活性剂的克拉夫特点、临界胶束浓度（CMC）、表面滞留以及其他表面和胶体特性的影响。在碳原子数一定的情况下，将酯基从离子头移至碳氢链的更中心位置可提高 CMC 值和钙离子稳定性，并降低乳液稳定性和水解稳定性。不过，润湿时间受这些化合物中酯基位置的影响不大。当酯基移到更中心的位置时，这些表面活性剂的克拉夫特点会降低。

  An adhesive composition including resin and electro-conductive material, wherein the electro-conductive material is one or more salts from sodium salt, potassium salt, and calcium salt of fluorosulfonic acid having 5 or more carbon atoms shown by the general formula (1): (R 1 —X—Y—SO 3 − ) n M n+ (1), wherein, R 1 represents a monovalent hydrocarbon group having 1-30 carbon atoms and optionally substituted by a heteroatom or optionally interposed by a heteroatom; X represents any of a single bond, ether group, ester group, and amide group; Y represents a linear or branched alkylene group having 2-4 carbon atoms, containing 1-6 fluorine atoms, and optionally containing a carbonyl group; M n+ represents any of a sodium ion, potassium ion, and calcium ion. This can form a living body contact layer for a bio-electrode with electric conductivity, biocompatibility, and light weight, which can be manufactured at low cost and without electric conductivity large lowering even when wetted with water or dried.

  An adhesive composition including a resin and electro-conductive material, wherein the electro-conductive material is an ammonium salt of fluorosulfonic acid having 5 or more carbon atoms shown by the general formula (1): (R 1 —X—Z—SO 3 − ) n M n+ (1), wherein, R 1 represents a monovalent hydrocarbon group having 1 to 40 carbon atoms and optionally substituted by a heteroatom or optionally interposed by heteroatom; X represents any of a single bond, ether group, ester group, and amide group; Z represents an alkylene group having 2 to 4 carbon atoms, containing 1 to 6 fluorine atoms, and optionally containing a carbonyl group; M + represents a cation having one or two ammonium cation structures. This can form a living body contact layer for a bio-electrode with excellent electric conductivity, biocompatibility, and light weight, which manufactures at low cost and does not cause large lowering of the electric conductivity even when it is wetted with water or dried.

  A series of sodium sulfoalkyl alkanoates, RCOO(CH2)jSO3Na, were prepared by means of sodium isethionate, propane sultone, and butane sultone with normal primary fatty acid composed of 10, 11, and 12 carbon atoms respectively. The effects of the position of the ester group on the Krafft point, the critical micelle concentration (CMC), the surface tention, and the other surface and colloidal properties of these surfactants were investigated. For a given number of carbon atoms, moving the ester group from the ionic head to a more central position in the hydrocarbon chain increased the CMC value and the calcium ion stalbility, and decreased the emulsion stability and the stability to hydrolysis. However, the wetting time was not strongly influenced by the position of the ester group in these compounds. The Krafft point of these surfactants decreased as the ester group was moved to a more central position.
