A solvent- solvent extraction is a type of extraction that is most commonly done by using two substances that are typically insoluble with each other. An acid-base extraction is a solvent-solvent extraction‚ in almost every case one of the solvents is water

Isolation of Acetyleugenol (Clove Oil) from Cloves Purpose In this experiment‚ you will obtain the essential oil from cloves by steam distillation. You will then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally‚ you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation‚ which will remove the organic solvent (dichloromethane). Background Whole cloves contain between 14% and 20% by weight of essential oils‚ but

A. Title – Acid-Base Extraction with Separatory Funnel B. Introduction – The main objective of the experiment was the extract an acid‚ a base‚ and a neutral compound from a 2:1:1 compound of benzoic acid‚ p-nitroaniline‚ and azobenzene. In theory‚ an extraction technique based on phase distribution should allow two immiscible solvents to separate with a portion of the solute distributed into each. Using a separatory funnel‚ acids were extracted with bases (NaOH)‚ and bases were extracted

ABSTRACT The extraction of pectin from orange peels has been studied at different sample to solvent ratios‚ different PHs and with different extraction techniques using water. The amount of pectin extracted reduces as the PH increased. This research work is been carried out in order to determine the process condition that will result
