Usage: Salicylaldehyde is a spice, is also a very wide range of organic synthesis intermediates. In drug synthesis commonly used in the synthesis of salicylic acid hydrazine (Salinazid), benzbromarone (Benzbromarone) and acetaminophenoxone.
Manufacture: By phenol and chloroform in sodium hydroxide solution obtained. Improved preparation method is o-cresol and phosphorus oxychloride or phosgene reaction, and then obtained by hydrolysis. Salicylic acid can also be reduced by electrolysis or by salicylic acid halide catalytic reduction in the system.
