Parchem – fine & specialty chemicals is the premier supplier of organic intermediates and plasticizers such as phthalic anhydride.  Phthalic anhydride [CAS 85-44-9] is versatile organic chemical intermediate for the plastics production industry.  Phthalic anhydride plays a large role in plastic manufacturing processes as a chemical building block for a variety of phthalate esters, which are commonly used plasticizers.  Phthalic anhydride is also used in the manufacture of polyester and alkyd resins for coating applications

Phthalic anhydride is produced by a number of methods, one of which is by dehydrating phthalic acid, a precursor to numerous phthalate derivatives.   Phthalic acid is the more reactive open-ring form of phthalic anhydride with dual carboxyl functional groups.  While phthalic acid is highly useful, manufacturers of plastics use phthalic anhydride more commonly for stability purposes.  Another method for producing phthalic anhydride is by the catalytic oxidation of ortho-xylene and naphthalene, a process that is used in industrial manufacturing.  The resulting phthalic anhydride is isolated and supplied as a white crystalline solid. 

Phthalic anhydride supplied by Parchem is commonly used as a chemical intermediate for the manufacture of various phthalate derivatives.  While most phthalic anhydride production is directed towards the plastics industry, phthalic anhydride derivatives are often used in the production of high quality epoxy resins and rubber processing applications.  It is also used as an organic intermediate in the production of various dyes and pigments that are applied to resins, coatings and plastics because of its inherent functions in plastics. 

Parchem – fine & specialty chemicals is an ISO 9001:2008 certified company that is committed to providing the highest quality of products and services accurately, on-time and on-budget.
