摘要:
Phloroglucinol may be produced by converting s-triacetyl benzene to benzene-1,3,5-tris-acetoxime which is a novel compound. Said acetoxime is subjected to a Beckmann rearrangement and the resulting mixture subsequently hydrolyzed to produce phloroglucinol.

摘要:
Hydroquinone is produced by hydrolizing p-aminophenol in an aqueous solution of ammonium bisulfate. The product hydroquinone is separated from the by-product ammonium sulfate and the byproduct regenerated to ammonium bisulfate for use in additional hydrolysis of p-aminophenol.
摘要:
Hydroquinone is made by electrolytically reducing nitrobenzene in an aqueous acid medium and thereafter maintaining the reaction medium containing the amino product, at a temperature of 200.degree. to 300.degree.C. for a sufficient time to hydrolyze the amino product to hydroquinone, and extracting the hydroquinone from the aqueous reaction medium.
