Polymeric catalysts are solid catalysts with a bead morphology which are primarily used for the manufacture of bulk and fine chemicals. These resin catalysts can advantageously replace mineral and organic acids and bases in such syntheses as phenol alkylation with olefins, condensation of aldehydes or ketones, esterfication of organic acids, or etherification of olefins with alcohols. Dow Water & Process Solutions’ catalysis technologies support the development and processing of chemicals used in industry every day.

Catalysis Applications
ACRYLATESAcrylic acid and its esters are some of the most versatile monomers for improving performance characteristics in thousands of polymer formulations. Major markets for esters include coatings, textiles, adhesives, paper and plastics. |
ALKYLATESAlkylphenols such as butylphenols, octylphenol, nonylphenol, and dodecylphenol enable the production of herbicides, gasoline additives, dyestuffs, polymer additives, surfactants, lubricant oil additives and antioxidants. |
ALCOHOLS (IPA, SBA)Isopropyl alcohol is produced through three different processes supported by Dow Water & Process Solutions technology. One is using indirect hydration and sulphuric acid as the catalyst, the second is using direct hydration with a heterogeneous polymeric acid catalyst. The third route is using acetone as the starting material. |
BISPHENOL ABisphenol A (BPA) is primarily used for polycarbonate and epoxy resins. Polycarbonate resin is used in automotive components, glazing sheet and optical media such as CDs and DVDs. Epoxy resins are used in protective coatings, electrical laminates and encapsulations, bonding and adhesives, glass fiber-reinforced materials. |
ESTERS, 1, 4, BUTENEDIOLButanediol is an important intermediate for engineering plastics and fibers. End product applications include polyurethane, PBT and polymers used to manufacture items such as training shoes and car parts. 1, 4-Butanediol (BDO) can be produced from maleic anhydride (MAH) and methanol using esterification and hydrogenation. |
FUEL ADDITIVESThe constant increase in demand for liquid fuels is the driving force for the petroleum industry. To satisfy high-performance engines and more and more strict exhaust emission standards, modern gasoline must meet exacting specifications which can vary from country to country. Oxygenates such as MTBE (Methyl tertiary-butyl ether), ETBE (Ethyl tertiary-butyl ether) or TAME (Tertiary amyl methyl ether) are added to gasoline to ensure clean combustion. |
SOLVENTS (MIBK)MIBK is a polar solvent with a moderate evaporation rate. This solvent is primarily used in surface coatings but is also employed in pharmaceuticals, pesticides and mining. As a chemical intermediate, MIBK is used in the manufacture of rubber antiozonants, mainly N-(1,3-dimethylbutyl)-N -phenyl-p-phenylenediamine (6PPD) and reacts with acetylene to produce acetylenic diol nonionic surfactant used in inks, paints/coatings, adhesives, dyes/pigments and pesticides. |
