Synthesis of Phenyl-2-Propanone (P2P) - [www.rhodium.ws]

16.3g (0.1 mole) phenyl-2-nitropropene was dissolved in 200ml methanol in a 250ml Erlenmeyer flask situated on a magnetic stirrer, and chilled to 0C with an ice/salt bath. Then, with good stirring, 7.6g (0.2 mole) of NaBH 4 was added a little at the time, and the temperature was not allowed to to rise above 15C.

Colorimeter (chemistry) - Wikipedia

A colorimeter is a device used in colorimetry that measures the absorbance of particular wavelengths of light by a specific solution. It is commonly used to determine the concentration of a known solute in a given solution by the application of the Beer–Lambert law, which states that the concentration of a solute is proportional to the absorbance.

Erlenmeyer flask - Wikipedia

An Erlenmeyer flask, also known as a conical flask (British English) or a titration flask, is a type of laboratory flask which features a flat bottom, a conical body, and a cylindrical neck. It is named after the German chemist Emil Erlenmeyer (1825–1909), who created it in 1860.. Erlenmeyer flasks have wide bases, with sides that taper upward to a short vertical neck.
