FORM - 2 THE PATENTS ACT, 1970 (39 of 1970) & THE PATENTS RULES, 2006 PROVISIONAL Specification (See Section 10 and Rule 13) PROCESS FOR THE PREPARATION OF 3-BROMO-FLUOROBENZALDEHYDE ADITYA BIRLA SCIENCE AND TECHNOLOGY COMPANY LIMITED an Indian Company, Aditya Birla Centre, S.K. Ahire Marg, Worli, Mumbai-400025, Maharashtra, India. THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION Field of the Invention This invention relates to a bromination reaction. Particularly, the present invention relates to a catalyst for bromination reaction. Still particularly, the present invention relates to a novel process for manufacturing of a catalyst which is utilized in the bromination reaction. Background of the invention Bromination is a chemical reaction that incorporates a bromine atom into a In this specification, the term bromination means an electrophilic aromatic bromination which is a type of electrophilic aromatic substitution. This organic reaction is typical of aromatic compounds and a very useful method for adding substituents to an aromatic system. Some aromatic compounds, such as phenol, reacts without a catalyst, but for typical benzene derivatives with less reactive substrates, a Lewis acid catalyst is required. Typical Lewis acid catalysts include A1CJ3, FeCi3, FeBr3, and 2nC12. The bromination reaction works by forming a highly electrophilic complex which attacks the benzene ring. Generally, bromo aromatics are widely used as intermediates in the manufacture of pharmaceuticals, agrochemicals an
