Questions asked by users might not always be phrased in the clearest way.
What is the black decomposition product of the decomposition reaction of isobutyl oleate at high temperatures? is it possible to separate those from my mixture when it consists of isobutyl oleate, isobutanol and sulfuric acid?
Accepted Answer
The black decomposition product of isobutyl oleate at high temperatures is likely a complex mixture of carbon-based compounds, including char, soot, and various hydrocarbons. These decomposition products form due to the breakdown of the oleate molecule and subsequent carbon-carbon bond formation.
Separating these decomposition products from your mixture is challenging. However, you can attempt the following:
1. Filtration: Use a filter paper to remove any solid char or soot particles.
2. Solvent Extraction: Try extracting the isobutanol and sulfuric acid with a suitable solvent like water or a dilute base. This may leave the decomposition products in the original phase.
3. Distillation: Distillation can separate the isobutanol and isobutyl oleate based on their boiling points. However, some decomposition products might co-distill.
It's crucial to note that the effectiveness of these methods depends on the specific conditions of your reaction and the properties of the decomposition products. A comprehensive analysis using techniques like gas chromatography-mass spectrometry (GC-MS) is needed to identify the specific components of the decomposition product mixture.
