isoprene could be obtained from turpentine, but this was too expensive and limited in supply.
isoprene is a very volatile liquid, boiling at a temperature of about 30 degrees Fahrenheit.
The difficulty lay rather in the cost of the raw material, isoprene.
Specimens of isoprene were made from several vegetable oils in the course of Dr. Tilden's work on those compounds.
You will see that the isoprene consists of a chain of four carbon atoms (represented by the C's) with an extra carbon on the side.
This is the first instance on record of the spontaneous change of isoprene into India rubber.
From this gas isoprene can be made and the isoprene converted into rubber by sodium, or acid or alkali or simple heating.
isoprene, from which Dr. Tilden produced India rubber, is comparatively a new product, as derived from oil of turpentine.
We can get isoprene by the distillation of turpentine—but why not bleed a rubber tree as well as a pine tree?
isoprene i·so·prene (ī'sə-prēn')
A colorless volatile hydrocarbon that is the naturally occurring basis of isoprenoids and that is used in the production of synthetic rubber.
A colorless, volatile liquid obtained from petroleum or coal tar and occurring naturally in many plants. It is used chiefly to make synthetic rubber. The isoprene in plants occurs in the chloroplasts and is used to build terpenes and other biologically important chemicals. Chemical formula: C5H8.
