Dean?Stark apparatus - Wikipedia
...The Marcusson apparatus, Dean-Stark apparatus, Dean?Stark receiver, distilling trap, or Dean?Stark Head is a piece of laboratory glassware used in synthetic chemistry to collect water [1][2] (or occasionally other liquid) from a reactor. It is used in combination with a reflux condenser and a distillation flask for the separation of water from liquids. This may be a continuous removal of ......

Dean-Stark apparatus | Resource | RSC Education
...There are many equilibrium reactions that yield water as a co-product. It is the co-produced water that prevents a high yield of product being obtained. The removal of the water is necessary to drive the reaction to completion and this is done using Dean-Stark apparatus. The reaction is carried out ......

Azeotropic distillation (Dean-Stark) - Chemistry Online
...The Dean-Stark apparatus can be used to perform azeotropic distillations in the laboratory, and is also particularly suitable for separating water from a reaction, e.g. in toluene/water mixtures. Azeotropic distillation is commonly used in the chemical industry to separate mixtures of liquids that cannot be separated through simple distillation....

Dean-Stark water separator - Big Chemical Encyclopedia
...Water samples are filtered and then the filtrate is extracted using either a separatory funnel procedure or a continuous liquid-liquid extraction procedure. The filtered particulates are extracted in a combination of a Soxhlet extractor and a Dean Stark water separator. [Pg.463] Oily Sludge /Wet Fuel Oil....
