Procedure

Methyl salicylate-formaldehyde resin condensate was prepared according to the following procedure: 22.8 parts of methyl salicylate, 3 parts of paraformaldehyde, 3 parts of glacial acetic acid and 0.6 parts of zinc chloride were placed in a boiling flask fitted with reflux condenser, thermometer, stirrer and heating mantle. The mixture was heated slowly with stirring until gentle reflux conditions were reached and maintained for approximately 48 hours until the last traces of paraformaldehyde sublimation disappeared.
