General description

Dodecylbenzenesulfonic acid solution (DBSA) is a non-volatile and non-hygroscopic acid catalyst majorly used in the trans-esterification reaction.

Application

DBSA can be used as a catalyst for the esterification of fatty acids (oleic acids) to produce biodiesel. It can be used as a Bronsted acid catalyst for the green synthesis of quinoxaline derivatives which are used in a variety of pharmacological profiles. It may be electrodeposited with polypyrrole(PPy) films on the aluminium alloy to protect against corrosion. Water based nanofluids with enhanced thermal conductivity and specific heat capacity may be prepared by doping polyanaline (PANI) into DBSA.
Dopant for conducting polymers strong acid catalyst for amino cross-linked coatings
