[Synthesis]

The first step, a hydrocarbonation reaction, involves distilling the composite gasoline to obtain a nonene fraction at 123-175 °C. The nonene reacts with naphthalene in the presence of concentrated sulfuric acid as a catalyst to produce dinonylnaphthalene (simultaneously, monononylnaphthalene and nonane are also produced). The reaction formula is as follows:
Synthetic Route
The second step, a sulfonation reaction, involves the reaction of dinonylnaphthalene with fuming sulfuric acid to produce dinonylnaphthalenesulfonic acid. The reaction formula is as follows:
Synthetic Route
The third step, barium sulfonation, involves the reaction of dinonylnaphthalenesulfonic acid with barium hydroxide to produce barium dinonylnaphthalenesulfonate (including neutral and basic barium dinonylnaphthalenesulfonate). The reaction formula is as follows:

[Chemical Properties]

Barium dinonylnaphthalenesulfonate is a dark brown viscous liquid with a melting point of 259-260°C, a boiling point of 600-601°C, a flash point of 170°C and is practically insoluble in water. Lethal Concentration: LC50 (rat) > 21,000 mg/m3/1hr.
[Uses]

Barium dinonylnaphthalenesulfonate is mainly used as an organic reagent in experimental studies to determine its micelle size in low-polar solvents[1].
