  • Heptachlor epoxide, the breakdown product of heptachlor, occurred in 12 percent of the samples, with an average level of 0.01 ppm and a maximum of 0.28 ppm.
  • heptachlor epoxide

Examples

  • Schlordanes is the sum of the concentrations of heptachlor, heptachlor epoxide, cis-chlordane, trans-chlordane, trans-nonachlor, cis-nonachlor, oxychlordane, and nonachlor III.

  • Well, ordinarily when you make glue... first you need to thermoset your resin... and then after it cools you mix in a, um, epoxide.

  • OK, so we do that and now we formed the epoxide, right.

  • Any reactions that give epoxides, they come by adding oxygen to an alkene.

  • Heptachlor was more than 10 times more abundant than its breakdown product, heptachlor-epoxide.

  • In 2010, his group reported unexpected associations between type 2 diabetes and environmental exposures to heptachlor epoxide and ?-tocopherol.

    Academic text (2012)
  • Heptachlor and its breakdown product, heptachlor epoxide, occurred in 44 percent and 12 percent of the samples, with mean values of 0.12 ppm and 0.01 ppm, respectively.

    Academic text (1993)
  • In the lab, the chemist synthesized an epoxide by adding a reagent to the alkene, resulting in a three-membered ring structure.

  • Researchers discovered that the epoxide formed during the reaction was crucial for the binding process in the study of drug interactions.

  • To create new materials, scientists often explore various epoxides because their unique structure allows them to link with different polymers.

epoxide singular
epoxides plural

Morphology

epoxide = oxide (semi-transparent) = ep + oxide

Contains 'oxide', which signals oxygen involvement, but the precise meaning (a three-membered ring structure) is a specialized chemical concept not derivable by an average B1 learner.

Etymology

Epoxide comes from the beginning part epi- meaning 'on' and oxide meaning a compound with 'oxygen'. Think of an epoxide as 'oxygen on' a very small ring of two carbon atoms, like the reactive part in epoxy glue, which explains why epoxides are small rings that react easily.
