/ˈd(j)uˌrin/

Origin: A borrowing from Latin, combined with an English element; modelled on a German lexical item. Etymons: Latin dūrus , -ene suffix.

Etymology: < classical Latin dūrus hard + -ene suffix, after German Durol, in the same sense (P. Jannash & R. Fittig 1870, in Zeitschr. f. Chem. 6 161); so called because it is solid at ordinary temperatures.

Chemistry.

A crystalline hydrocarbon occurring naturally in coal tar and also made synthetically, used in the manufacture of polyimides and plastics.Systematic name:1,2,4,5-tetramethylbenzene; C₆H₂(CH₃)₄.
