| 摘要 |
Water-soluble sulfonated dispersants are disclosed which derive from the reaction between SO3 and indene, or indene mixtures with aromatic compounds. The resulting sulfonates are useful in order to fluidify and pump concentrated coal water mixtures along long distances; these compounds find also use as super-fluidifiers for concrete. <IMAGE> |
