Title:
HETEROGENICALLY CATALYSED GAS-PHASE PARTIAL OXIDATION FOR PRECURSOR COMPOUNDS OF (METH)ACRYLIC ACID
Document Type and Number:
WIPO Patent Application WO2002062737
Kind Code:
A3
Abstract:
The invention relates to a method for the heterogenically catalysed gas-phase partial oxidation of precursor compounds of (meth)acrylic acid in a fixed catalyst bed, containing as the catalyst an activated mass of mixed oxide, shaped to form a geometric body. Said geometric body is a geometric base body, into whose surface a cavity is incorporated.
