The flask was surrounded with a beaker of cold water to cool it during the addition of concentrated sulfuric acid. a. 10cm3 of sulfuric acid was placed gradually in the separatory funnel while carefully swirling the apparatus from time to time. b. The funnel was removed from the reflux condenser and the flask from the water bath. c. The apparatus

INTRODUCTION Isopentyl acetate‚ "banana oil"‚ is a naturally occurring compound that possesses a distinctive odor. It is found in bananas‚ as well as many other organisms. This experiment attempts to produce isopentyl acetate by heating under reflux‚ which involves heating the mixture in a flask with a condenser placed vertically in the neck since any escaping vapours condense and run back into the flask‚ by combining isopentyl alcohol with acetic acid and an acid catalyst. The product was isolated

water and butan-2-ol. Procedure 1. The room temperature was recorded. 2. 15cm3 of the given aqueous ethanoic acid and 15cm3 of butan-2-ol were poured into a 100cm3 separating funnel‚ using suitable apparatus. The funnel was stoppered and was shook vigorously for 1 to 2 minutes. (The pressure in the funnel was released by occasionally opening the tap.) 3. 10cm3 of each layer was separated approximately. (The fraction near the junction of the two layers was discarded.) 4. 10.0cm3 of

placed into a separatory funnel. The unknown mixture contained a basic compound so 15mL of HCl was added to the separatory funnel and shaken up to mix. With the stopper in place on the separatory funnel‚ the two layers separated‚ the bottom layer was drained into a beaker‚ this was the water layer of the solution and set aside for further testing later. To recover the neutral compound from the ether solution‚ 15mL of saturated aqueous NaCl was added to the separatory funnel using the same technique

precipitate can be measured very accurately using the funnel with filter paper. Subsequently‚ because the funnel is ceramic‚ it can withstand higher temperatures‚ and thus a more vigorous drying procedure. This allows the maximum amount of water to be removed‚ and will consequently reduce it as a source of error. Experimental Method 1. Obtain a Buchner funnel form the drying oven using crucible tongs and place it in a desicooler. Allow the funnel to cool for 60 minutes. Remove from desicooler

The Discussion of this experiment began with discussing how many materials we use today are actually mixtures of pure substances. The separation of these materials into their pure substances can be quite challenging. When we are discussing separations of a mixture that contains pure substances‚ it all depends on whether you can separate the substances by physical means. That means‚ utilizing each substances physical properties such as boiling point‚ melting point‚ and magnetism. Separation of a

Revenue allocation is the distribution of revenue‚ or total income‚ through a business‚ corporate or government structure. It often involves a complex process of determining how and where to funnel revenues in order to best maintain the viability and operating structure of an organisation.

Synthesis of t-Pentyl Chloride Introduction: Using SN1 reaction mechanism with hydrochloric acid‚ t-Pentyl alcohol was converted to t-Pentyl chloride in an acid catalyzed reaction. The reaction took place in a separatory funnel designed to separate immiscible liquids. The crude product was extracted by transferring a solute from one solvent to another. The process of washing the solutions by phase transfer was used in order to remove impurities from the main solvent layer. Finally‚ the crude

seperaton process is used to transform a mixture into two or more distinct products. Filtration is the most common method of separation of an insoluble solid from a liquid. The filtration process involves the use of a filter paper being placed in a funnel. The filter drains through the filter paper into the beaker. This leaves the residue inside the filter paper and the filtrate in the beaker. Evaporation is the technique most commonly used when recovering the solute from a solution. The evaporation
