Plasticizers (DOP and others)

 

TECHNOLOGY FOR THE PRODUCTION OF PLASTICIZERS (DOP and others)

 

CONSER offers a highly reliable and advanced technology for the production of Di-Octyl Phthalate (DOP) practised in plants of the SISAS group.

 

CONSER can provide the technology for both the conventional process, using a strong acid catalyst, and the new process, based on a metal catalyst, which has brought huge benefits.
The high selectivity of the metal catalyst has practically eliminated the formation of by-products, making unnecessary any purge in the recycle of the excess alcohol.
No neutralization or washing steps of the product are necessary and the problems of waste management are substantially reduced.

 

The product meets high standards of colour, and discoloration is not necessary.

 

CONSER process is extremely flexible: through the variation of process conditions and raw materials, the same plant equipment can also produce other plasticizers:

  • Phthalates: dibutyl-phthalate, diisobutyl-phthalate, dimethyl and diethyl-phthalate.
  • Non-Phthalates: dimethyl-succinate, dibutyl-maleate (DBM), dioctyl-maleate (DOM), etc.

Trimellitic Anhydride (TMA)

 

TECHNOLOGY FOR THE PRODUCTION OF TRIMELLITIC ANHYDRIDE (TMA)

 

Trimellitic Anhydride (1,3–Dihydro-1,3 Dioxo–5–Iso-benzofurancarboxylic acid, TMA) is a very reactive chemical of relatively low molecular mass.
Many of its industrial uses depend on the reactivity of the anhydride group.
It is mainly used in the synthesis of trimellitate esters, used as plasticizers of PVC and other various synthetic resins, especially when temperature and water stability are required.

Other TMA applications include:

  • - Adhesives
  • - Solvent-borne and waterborne coatings
  • - Powder coatings
  • - Binder for aggregates
  • - Curing agent for epoxy and other resins
  • - Paints

Isophthalic Acid

 

TECHNOLOGY FOR THE PRODUCTION OF ISOPHTHALIC ACID

 

Isophthalic Acid (Benzene - 1,3–Dicarboxylic acid) is an aromatic di-carboxylic acid industrially produced by the oxidation of m-xylene.

 

It is used as a component of PET (poly-ethylene terephthalate), which is mainly used to produce plastic bottles for drinks, films, and food packaging.
Isophthalic acid reduces the crystallinity of PET, increasing its operability and improving its clearness.

Isophthalic acid is a component of high-quality alkyds and polyester resins for coatings and unsaturated polyesters for fiberglass-reinforced plastics applications.

CONSER can offer technology of production of Isophthalic acid either based on low-temperature oxidation reaction (activated by aldehyde) or on high-temperature oxidation reaction (activated by bromine).

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.
