Notice in the structural diagram: the SO3 hooked to the benzene ring, that is the dodecylbenzen sulfonic acid. Now the Na+ ison, that is from the soda ash Na2CO3. The exact formula will depend on which fatty acids form. Generally, one would expect Sodium dodecylbenzenesulfonate C18H29NaO3S
hello
dodecyl sulfonic acid +soda ash i would like to have a balance of this reaction and to know the share amount of reactant in purpose a ideal synthese.sincerly yours.

I found, on searching Google, the formula C12H25SO3H for dodecylsulfonic acid (otherwise called laurylsulfonic acid). The reaction with Na2CO3 would be
2C12H25SO3H + Na2CO3 ==> 2C12H25SO3Na + H2O + CO2
I found many references to dodecylbenzenesulfonic acid, C18H29SO3H, also used in detergent manufacturing, but I do not believe these are the same molecule. Dodecylbenzenesulfonic acid is an ABS; i.e., an alkylbenzenesulfonate which is a linear detergent.
