Phthalic Anhydride (PA)

 

TECHNOLOGY FOR THE PRODUCTION OF PHTHALIC ANHYDRIDE (PA)

 

CONSER is in position to offer a well established and highly reliable Phthalic Anhydride (PA) technology based on the selective oxidation of o-xylene to PA, practiced in plants of the SISAS group.

 

The key features of the technology are:

Reliability: since SISAS has been the largest PA producer in the world, the technology has been commercially proven to the maximum possible extent.

Easiness of operation: the technology is easy to operate, does not require highly sophisticated catalysts or equipment, does not entail extreme operating conditions.

TECHNOLOGY FOR THE PRODUCTION OF SPECIAL ANHYDRIDES

 

CONSER is in position to offer the technology for the production of special anhydrides, which are used in the fields of coatings, epoxy resin curing agents, polyester resins, adhesives, plasticizers, pesticides, etc.                        These anhydrides include tetra and hexahydrophthalic anhydrides (THPA, HHPA), or methyltetra (MTHPA) and methyl-hexa (MHHPA) derivatives.

 

THPA and MTHPA are produced by the Diels-Alder reaction of Maleic Anhydride (MAN) respectively with butadiene or isoprene.

 

HHPA and MHHPA are produced by hydrogenating either THPA or MTHPA.
