Dubenzila dusulfidoC14H14S2 estas kemia kombinaĵo, apartenanta al la funkcia grupo de la dusulfidoj de la dusulfida acido kaj tiobenzila alkoholo. Dubenzila dusulfido estas senkolora aŭ likvaĵo kun penetranta sulfura odoro, analiza reakciaĵo uzata en kemiaj sintezoj kaj en la fabrikado de kosmetikaĵoj kaj farmaciaĵoj. Kutime ĝi estiĝas per kondensiĝa reakcio aŭ per esterigo de Fischer-Speyer kun sulfata acido kiel katalizilo. Dubenzila dusulfido estas malmulte solvebla en akvo, sed tute solvebla en alkoholo, duetila etero, kloroformo kaj plejmulto el la organikaj solvantoj. Dubenzila dusulfido reakcias kun fortaj oksidigagentoj kaj fortaj bazoj. Dusulfidaj esteroj malkomponiĝas per varmigo aŭ kun la tempopaso en sulfuro aŭ sulfuraj derivaĵoj.
