query: What are the different methods to synthesize resorcinol?
answer: Resorcinol can be synthesized through several methods, including dialkylation of benzene with propylene followed by oxidation and Hock rearrangement; disulfonation of benzene followed by hydrolysis (though this method is now obsolete due to sulfur waste); melting resins (like galbanum and asafoetida) with potassium hydroxide; distillation of Brazilwood extract; melting 3-iodophenol or phenol-3-sulfonic acid with potassium carbonate; diazotization of 3-aminophenol or 1,3-diaminobenzene followed by hydrolysis; and fusion of ortho- and para-compounds of the aromatic series (e.g., bromophenols, benzene-para-disulfonic acid) with potassium hydroxide.
