| Applications | Uses: Used as a fire-retardant monomer in unsaturated polyester resins, wool fabrics, coatings, epoxy resins, and polyurethane foams, Also used as an extreme pressure lubricant, chemical intermediate, and for special applications in electronic systems, paneling, engineering plastics, paints, and anti-corrosion tanks, pipes, and other equipment, [HSDB], Painting (Pigments, Binders, and Biocides) [Category: Paint], Plastic Composites Manufacturing [Category: Industry], Textiles (Printing, Dyeing, or Finishing) [Category: Industry], Flame retardant, FIRE-RETARDANT MONOMER IN UNSATURATED POLYESTER RESINS, FIRE RETARDANT MONOMER IN COATINGS, IN EPOXY RESINS, IN POLYURETHANE FOAMS, EXTREME PRESSURE LUBRICANT, CHEM INT FOR DIBUTYL & DIMETHYLCHLORENDATE (PLASTICIZERS), Chlorendic acid used primarily as a chemical intermediate in the manufacture of unsaturated polyester resins, and with special applications in electronic systems, engineering plastics and paints. A major use is in fiberglass reinforced resins for process equipment in chemical industries. Chlorendic acid is also used to impart flame resistance to polyurethane foams when reacted nonhalogenated glycols to form halogenated polyols and can be used in the manufacture of alkyd resins for special paints and inks., In Europe, 80% of the chlorendic acid produced is used in composites for flame retardant building and transport materials. The remainder issued in composites for the manufacture of anti-corrosion equipment, such as tanks, piping and scrubbers. In the USA, Latin American and Far East, the usage pattern is reversed, 70-80% is used for anti-corrosion equipment and 20-30% for flame retardant applications., In the textile industry, the primary use for chlorendic acid is for flame retardant treatment of wool fabrics. The natural flame resistance of wool is enhanced by finishing treatments with chlorendic acid in dimethylformamide., Industry Uses: Other, Methods of Manufacturing: Chlorendic acid is synthesized by a Diels-Alder reaction of maleic anhydride and hexachlorocyclopentadiene in toluene followed by hydrolysis of the anhydride using aqueous base., Formulations, Preparations: Commercial grade 99.5% ...Common impurities are as follows: unreacted maleic anhydride, <, =0.25%, Fe, =1 ppm, hexachlorocyclopentadiene, =50 ppm, moisture, =1%, other volatiles, Trade name: HET acid, U.S. Production: 2023: 49, 851 lb, 2022: 51, 251 lb, 2021: 49, 046 lb, 2020: 30, 863 lb, (1972) PROBABLY GREATER THAN 4.54X10+5 GRAMS, (1975) PROBABLY GREATER THAN 4.54X10+5 GRAMS, U.S. Imports: (1973) 1.91X10+8 GRAMS (PRINCPL CUSTMS DISTS), General Manufacturing Information: Plastics Material and Resin Manufacturing, Bicyclo[2.2.1]hept-5-ene-2, 3-dicarboxylic acid, 1, 4, 5, 6, 7, 7-hexachloro-: ACTIVE |
