Title:
METHOD AND APPARATUS FOR PREPARING MONOFUNCTIONAL AROMATIC HALOFORMATES
Document Type and Number:
WIPO Patent Application WO2000058259
Kind Code:
A9
Abstract:
A continuous process for the preparation of monofunctional aromatic haloformates (MAH) having structure (I) wherein n is an integer from 1 to 5, and R1 represents hydrogen, a branched or unbranched alkyl group having from 1-15 carbon atoms, an aryl group which may be substituted or unsubstituted, a cycloaliphatic group which may be substituted or unsubstituted, or an arylalkyl group which may be substituted or unsubstituted, and X is F, Cl, Br or I the method comprising the steps of (a) introducing (1) an aqueous caustic solution; 2) a carbonyl chloride; 3) at least one monofunctional hydroxyaromatic compound; and 4) at least one inert organic solvent into a continuous reaction system; and (b) effecting contact between 1), 2) 3) and 4) for a time and at conditions sufficient to produce MAH of structure (I).
