In chemistry, a condenser is laboratory apparatus used to condense vapors – that is, turn them into liquids – by cooling them down. [ 1 ] Condensers are routinely used in laboratory operations such as distillation , reflux , and extraction .
The aqueous solution in the classical reaction contains glucose, sodium hydroxide and methylene blue. [14] In the first step an acyloin of glucose is formed. The next step is a redox reaction of the acyloin with methylene blue in which the glucose is oxidized to diketone in alkaline solution [6] and methylene blue is reduced to colorless leucomethylene blue.
In chemistry, fractional crystallization is a stage-wise separation technique that relies on the liquid-solid phase change. fractional crystallisation. This is an old established method which is nevertheless capable of excellent results and a description is available in "The practical Methods of organic Chemistry" by Ludwig Gattermann in 1898 and a translation was available in English by ...
