In this experiment‚ the essential oil eugenol was isolated from ground cloves using steam distillation techniques. Eugenol had a high boiling point‚ but it was isolated at a lower temperature by performing a co-distillation with water‚ a process known as steam distillation. This technique allowed the desired material to be distilled at a lower temperature than 100℃. The point of the steam distillation was to use an azeotrope to isolate the organic compound from a solid. The azeotrope was the liquid

apparatus and isolate a natural product from cloves. Introduction By performing steam distillation we can isolate eugenol at lower temperature than its usual boiling point of 248 degree Celsius. Eugenol belongs to a category called essential oil. Many of these compounds are used as flavoring and perfumes and in the past were considered the essence of plant from which they were derived.

Introduction Eugenol is a naturally occurring chemical that has medical applications such as its use as a natural dental anesthetic. It can be extracted from cloves by using the method of steam distillation. The extracted compound will then be separated from the water using methyl chloride‚ which will then be evaporated using a rotary evaporator leaving only the essential oil‚ Eugenol. IR spectroscopy will be used to determine the structure of the extracted compound. Results and Discussion Four

Experiment 7- Isolation of the Major Component of Clove Oil Pre-Lab Questions: 1.) Briefly explain the concept of steam distillation. What is the difference between a simple distillation and a steam distillation? When a mixture of two immiscible liquids are distilled it is referred to as codistillation. This process is referred to as steam distillation when one of the liquids is water. This distillation is used to separate organic liquids from natural products and reaction mixtures in which

Steam distillation of cloves produced 0.53g of an oil which contained in its IR spectrum the functional groups O-H (at 3520 cm-1)‚ sp2 C-H (3080 – 3000 cm-1)‚ aliphatic C-H (2980 – 2940 cm-1)‚ and both alkene C=C (at 1640 cm-1) and aromatic C=C (at 1514 cm-1). The IR spectrum is attached to this report. These data are consistent with the structure of eugenol‚ shown in Figure 2 below: In addition‚ the IR of the product from the steam distillation of cloves closely corresponds with that of an

Distillation – Clove Oil Abstract: In this experiment‚ a situ method steam distillation was performed and essential oils were isolated from cloves. Once the oils were obtained‚ extraction techniques were used to extract a crude‚ eugenol‚ and acetyleugenol product sample. These samples were submitted for GC analysis and the normalization area percents were calculated to confirm their purity; for the crude sample it was 93.95% eugenol and 6.05% acetyleugenol‚ for the eugenol sample it was 100%

Acetyl chloride‚ CH3COCl‚ also known as ethanoyl chloride or acyl chloride‚ is an acid chloride derived from acetic acid. It belongs to the class of organic compounds called acyl halides. It is a colorless liquid. Acetyl chloride does not exist in nature‚ because contact with water would hydrolyze it into acetic acid and hydrogen chloride. In fact‚ if handled in open air it gives off white smoke owing to the hydrolysis from the moisture in the air. The "smoke" is actually small droplets of hydrochloric
