制备方法与用途

化学性质
白色结晶或粉末，易溶于水而不溶于醇。

用途
主要用于有机合成，并用作动物胶的乳化剂。此外，也用于有机合成。

生产方法
由萘经磺化生成2-萘磺酸，再使用氧化钙的水悬浮液中和，过滤。将2-萘磺酸钙盐的稀滤液浓缩、冷却后结晶并过滤。随后，将滤饼溶于热水中，加入饱和碳酸钠溶液以调节至碱性，冷却后滤除碳酸钙，再次浓缩并冷却结晶，最终获得2-萘磺酸钠。

  Water soluble fluors useful in enhancing images obtained in autoradiography have the general formula: F is a moiety which acts as a fluor, e.g., a dehydro derivative of a compound which is a fluor; preferred examples include 4-(2,5-diphenyloxazolyl), 1-naphthyl-methyl, 2-naphthyl, and 4-[5-(2-phenyloxazolyl)]phenyl. S is a surfactant moiety which makes the molecule hydrophilic, e.g., dehydro derivatives of surfactants; preferred examples include polyethylene glycol derivatives, sulfonic acids or salts thereof, aryl sulfonates, amines and quaternary ammonium compounds. B is a binding moiety which chemically binds the fluor moiety F with the surfactant S, and may be a chemical bond, or a disubstituted moiety such as an alkylene, e.g., methylene group. The variables x, y and z are integers which can generally vary from 1 to 10. A number of such compounds are disclosed, as well as methods of using such compounds, as well as compositions and products for fluorographic analysis in connection with chromatography, electrophoresis etc.

• Sulfonic acid compound having cyclopentadiene skeleton and composition comprising same and cement
  申请人：JAPAN SYNTHETIC RUBBER CO., LTD.

  公开号：EP0108654A1

  公开（公告）日：1984-05-16

  Compounds having a cyclopentadiene skeleton and at least one sulfonic acid group are novel, and produced by subjecting cyclopentadiene, dicyclopentadiene and/or hydroxydicyclopentadiene to sulfonation, and subjecting the same, before or after the sulfonation, to reaction with alkylbenzene, polymerization and/or condensation through an aldehyde. The aforesaid compounds are useful as dispersants for cement. By incorporating a polymer emulsion into a slurry composition comprising a powder and a dispersant having at least one sulfonic acid group the proportion of said polymer emulsion being 0.05 to 50 parts by weight per 100 parts by weight of said dispersant, the dispersing effect of said dispersant is improved, the fluidizing effect of the dispersant is further enhanced, the slump loss is made very small, and the workability becomes good.

  具有环戊二烯骨架和至少一个磺酸基团的化合物是新型化合物，其生产方法是将环戊二烯、双环戊二烯和/或羟基双环戊二烯进行磺化，并在磺化之前或之后使其与烷基苯反应、聚合和/或通过醛缩合。上述化合物可用作水泥的分散剂。 通过将聚合物乳液加入由粉末和至少有一个磺酸基团的分散剂组成的浆料组合物中（所述聚合物乳液的比例为 0.05 至 50 重量份/100 重量份所述分散剂），可以改善所述分散剂的分散效果，进一步提高分散剂的流化效果，使坍落度损失非常小，并具有良好的可加工性。
