When SO3 itself is employed, the concentration is at a maximum and the initial stage of the sulfonation is completed easily and rapidly. However, the sulfonic acid formed in the initial stage easily reacts with a second mole of SO3 to form a complex which may be much less reactive than SO3 itself. Thus, when reacting a hydrocarbon with SO3 on an equimolar basis, one half of the hydrocarbon is sulfonated with SO3 and the other half is sulfonated by the less reactive complex (see the section on Kinetics). Likewise, when sulfonating organic acids with SO3, the initial reaction product is an acyl sulfate which is next converted to the desired sulfonate under considerably more drastic conditions. The second half of these reactions is the slower, and the rate and reaction conditions are determined by the stability of the initial complex, which varies greatly. The benzene-sulfonic acid-S03 complex is quite reactive, while that from naphthalene-disulfonic acid is comparatively unreactive. When SO3 is used for sulfation, the reaction appears simpler ... 

Carbon disulfide and carbon oxysulfide are volatile substances with low to moderate toxicity. The psychopathological effects of carbon disulfide arising from chronic exposure include neuritis, bizarre dreams, insomnia, irritation, and excitation. Carbon oxysulfide is an irritant and narcotic at high concentrations. Very little information is available on the human toxicity of sulfides, disulfides, and sulfones. Organic sulfur compounds are notable for their disagreeable odor. In an extremely pure state, several such compounds have a mild sweet odor. A detailed discussion of the toxicity of individual compounds of commercial interest is presented in the following sections. 

Superplasticizers were discovered in 1960s. The poly- 3-iiaphthalene sulfonates were the first to be introduced and the most widespread superplasticizers followed by polymelamine sulfonates. Organic polymers having carboxylic group are the most recent...
