The present invention provides a green catalytic process for the synthesis of acetyl salicylic acid using solid acid catalysts at atmospheric pressure. The invention involve the solid acid catalyst such as sulfated transition metal oxides namely nano-cry
The acylation of 2-methoxynaphthalene with acetic anhydride was carried out over zeolite beta catalysts having various Si/Al ratios. It was found that the reaction performance is strongly dependent on the Si/Al ratio of the catalyst. The catalytic reaction features were elucidated in terms of the...
