PDF How to set up a reflux apparatus Fischer Esterification reaction using reflux technique in organic chemistry lab. Normally, the whole process including the setup and the reaction will take about 2 hours. However, the general principles and the instructions on setting up the reflux apparatus can be applied to any reactions that needed to be heated for a long time. Reflux in industrial distillation The diagram shows a typical reflux apparatus. It includes a water bath to indirectly heat the mixture. As many solvents used are flammable, direct heating with a Bunsen burner is not generally suitable, and alternatives such as a water bath, oil bath, sand bath, electric hot plate or heating mantle are employed. Reflux in laboratory distillation PDF Core practical 5: Investigate the oxidation of ethanol Diagram fig A Reflux apparatus fig B Distillation apparatus Procedure 1. Carefully add 20 cm3 of acidified sodium dichromate solution to a 50 ml pear-shaped flask. Cool the flask in an ice-water bath. 2. Set the flask up for reflux (see fig A) keeping it in the ice-water bath. 3. Place a few anti-bumping granules into the pear-shaped flask. 4.

lpreflux A simple reflux apparatus is shown in Figure 1 on the right. To set up the reflux apparatus, set a stirrer/hot plate and ring stand in the hood. Place a heating mantle on the stirrer. Insert a round bottom flask (distilling flask) into the heating mantle and clamp the neck of the flask to the ring stand. Applications | DWK Life Sciences Jointed glass components connected to easily construct laboratory apparatus. Ideal for extraction, reflux, fractionation, and distillation.

Organic Chemistry - What is Reflux? - A-Level H2 Chemistry ... Diagram below shows the basic set-up of Refluxing: (Source of diagram: Wikipedia) Reflux involves heating the chemical reaction for a specific amount of time, while continually cooling the vapour produced back into liquid form, using a condenser. Setup of Reflux apparatus - University of California, Los ... Apr 10, 2003 · The inlet of the water is on the lower end of the condenser, the outlet at the upper end independent if the condenser is used for reflux or distillation. This way you will require a lower flow rate for cooling, because the outer jacket of the condenser will fill up with water first before it reaches the outlet at the top. 4. Heating. a. Micro-scale
