cyclopropane

 [si″klo-pro´pān]
a colorless, flammable gas with a characteristic odor and pungent taste that is an inhalational anesthetic; now little used because of its flammability.

cy·clo·pro·pane

(sī'klō-prō'pān),
An explosive gas of characteristic odor; in the past, widely used to produce general anesthesia.
Synonym(s): trimethylene

cyclopropane

(sī′klə-prō′pān′)
n.
A highly flammable, explosive, colorless gaseous cycloalkane, C3H6, sometimes used as an anesthetic.

cyclopropane

A powerful, non-irritating anaesthetic gas. It has the disadvantages of being explosive and of causing heart irregularity in the presence of adrenaline.

Poly(trimethylene terephthalate) (PTT) was first synthesized and patented in 1941 (Whinfield and Dickson 1941), but it was not produced commercially because of the expense of one of the precursors, 1, 3-propanediol (PDO; Chuah et al.1995A).
