Abstract
Abstract: sulfa drugs acetanilide is the raw material, can be used as analgesics, antipyretic agents and preservatives. Used to make dyes intermediates of nitro acetanilide, p-nitroaniline and p-phenylenediamine. In the industrial rubber vulcanization accelerator can be used for fiber coating resin stabilizer, hydrogen peroxide stabilizer, as well as for synthetic camphor and so on.
To do with glacial acetic acid and aniline acetylation reagent preparation acetanilide, three take different amounts of reagents were prepared acetanilide. Recrystallized with hot water, refined acetanilide, weighing calculate yield. During the preparation of acetic acid Aniline precautions, as well as the factors that affect yield.
Key words：sulfa drugs acetanilide, preparation ,recrystallization
