The Dakin reaction refers to the transformation of ortho- or para-hydroxy aromatic aldehydes or ketones into corresponding phenols under basic conditions using hydrogen peroxide. This reaction was discovered by Henry Drysdale Dakin in 1909, and is named in his honor. It is an efficient method for synthesizing polyhydroxy aromatic compounds....

Aromatic hydrocarbonization reaction is a widely used method in enzyme immobilization technology. It involves alkylating and aromatizing polymers with halogen-substituted aromatic rings or heterocycles, followed by reactions with amino, phenol, or sulfhydryl groups on enzyme molecules under alkaline conditions. Aromatic hydrocarbons, commonly referred to as aromatics, are fundamental components of...

A glass spotting capillary is a thin, cylindrical, or micro-tapered glass tube characterized by its slender structure. With diameters often below the millimeter scale and lengths extending up to tens of centimeters, these tubes feature thin walls, making them ideal for various laboratory operations. Common uses include liquid distribution, mixing,...
