Description

Technical Field

[0001] The utility model relates to a vacuum feeder, belonging to the technical field of isobutylbenzene production. Background Art

[0002] Isobutylbenzene is the raw material for producing ibuprofen, a new analgesic, antipyretic and anti-inflammatory drug. The potassium carbonate used in the isobutylbenzene synthesis reaction is in the form of powdered solid particles.
