Examples from the Web for isoprene
Isoprene could be obtained from turpentine, but this was too expensive and limited in supply.
The difficulty lay rather in the cost of the raw material, isoprene.
Isoprene, from which Dr. Tilden produced India rubber, is comparatively a new product, as derived from oil of turpentine.
This is the first instance on record of the spontaneous change of isoprene into India rubber.
Isoprene is a very volatile liquid, boiling at a temperature of about 30 degrees Fahrenheit.
- a colourless volatile liquid with a penetrating odour: used in making synthetic rubbers. Formula: CH 2 :CHC(CH 3):CH 2Systematic name: methylbuta-1,3-diene
C20: from iso- + pr (opyl) + -ene
