Biodegradability    biodegradable.
Characteristics    excellent permeating, wetting, dispersing, emulsifying abilities. When system contains a small amount of sodium chloride, can be significantly enhanced permeating abilities. Certain resistance to inorganic electrolytes.
Synthesis
Naphthalene, butanol and concentrated sulfuric acid react through the sulfonation condensation reaction, then sodium hydroxide or sodium carbonate neutralizes, finally obtain product.
