Why is steam distillation used to isolate this compound from cloves instead of simple distillation? 5. Based on the functional groups present in your structure from 3a), suggest one simple chemical test (including expected observations) to confirm that steam distillation can be used to isolate this ENG 4:11 PM 4 us 2017-06-06Explanation / Answer
Question 1.
simple distillation = is typically used to separate 2 compounds which have different boiling temperature, therefore, one will vaporize first, then this can be separated, then condensated and purified.
The "bottoms" will remains liquid most of the time. we tpyically adda reflux in order to increase purity
fractional distillation = this may be used for 3 or more species, then we separate at least 3 streams of products, which typically is rich in each of the species used. This is usefull specially in petrochemical applications
