General description
Application
- As an etching agent for the laser modified silica glass. It selectively facilitates etching on exposure to femtosecond laser.
- As a catalyst for the transformation of palm oil along with methanol to methyl esters, via transesterification reaction.
- Preparation of potassium hydroxide catalyst supported on palm shell activated carbon, which is used for the transesterification of palm oil.
- To improve the catalytic efficacy of X, Y and ZSM (Zeolite Socony Mobil)-5 zeolites during the synthesis of methyl methacrylate.
