Title:
METHOD FOR MANUFACTURING BUTADIENES
Document Type and Number:
Japanese Patent JP2012152679
Kind Code:
A
Abstract:
To provide a catalyst process in which catalytic activity is free from deterioration with time by suppressing polymerization of highly polymerizable DMB on an acid point, in manufacturing DMB from PCN by a vapor-phase method using a solid acid catalyst.
Under a hydrogen carrier gas atmosphere, 2,3-dimethyl-1,3-butadiene is continuously manufactured by rearrangement/dehydration reaction of 3,3-dimethyl-2-butanone by a vapor-phase process using a catalyst with a solid oxide carrier carrying cobalt oxide (II), cobalt (III), or copper oxide (II).
