Limonene will be steam distilled from orange rinds; the resulting mixture of water and limonene will be allowed to separate, and the limonene removed via Pasteur pipet. 1 The d-limonene limonene recovered from orange peel from the conversion of press liquor to molasses, d-limonene is used for making everything from adhesive to a solvent used by the electronic industry as a replacement of ozone depletion chlorofluorocarbons.limonene is a hydrocarbon classed as a terpene, it is a clear coloured liquid at a room C. QUESTIONS: 1. (2021) Once heated, a 30mL distillate was obtained. isoprene units it possesses. This is most likely due The peel of oranges is boiled in water and the oil produced {limonene} distilled in steam at a temperature just below 100 0 3 0 A C, well below its normal boiling point. 2 Function of limonene Find ready-to-use experiments that help you integrate data collection technology into your curriculum.
