Dye Organic Intermediate Phthalic Acid CAS 88-99-3 Polyester Resin Plasticizer

Dye Organic Intermediate Phthalic Acid CAS 88-99-3 Polyester Resin Plasticizer

Introduction:

Colorless flaky crystals. Melting point 234℃ (phthalic anhydride is generated when heated to above 200℃), relative density 1.593. Soluble in methanol and ethanol, slightly soluble in water and, insoluble in chloroform.

Uses:

Used in synthetic resins, synthetic fibers and medicines. Since phthalic acid and phthalic anhydride have similar chemical properties, phthalic anhydride is often produced directly in industry. In applications, phthalic anhydride can be used instead of phthalic acid. The oral LD50 for rats is 7.9g/kg. Used in the manufacture of dyes, polyester resins, polyester, medicines and plasticizers. Prepare standard solutions as alkalinity standards. Verify cobalt, copper, germanium, mercury, nickel, potassium, strontium and zinc, and determine cobalt, iodate and lead. Organic synthesis.
