[Combinaison complexe d’hydrocarbures obtenue par distillation extractive de naphta et/ou de gazole de craquage thermique. Se compose d’hydrocarbures paraffiniques et oléfiniques, principalement des iso-amylènes tels que le méthyl-2 butène-1 et le méthyl-2 butène-2, dont la température d’ébullition est comprise approximativement entre 31 °C et 40 °C (88 °F et 104 °F).]
