Txoj kev tsim khoom
Txoj kev tshuaj tiv thaiv ntawm salicylic acid thiab dimethyl sulfate: Salicylic acid yog yaj hauv sodium hydroxide tov, txias kom qis dua 20 degree, thiab dimethyl sulfate ntxiv dropwise. Qhov kub yog tswj ntawm li 20 degree. Tom qab ntxiv ib nrab ntawm nws, sodium hydroxide tov yog ntxiv dropwise tib lub sij hawm. Tom qab ntxiv, nws yog rhuab mus rau 95 degree nyob rau hauv 1 teev, thiab sodium hydroxide tov yog ntxiv dropwise. Do thiab reflux rau 6 - 7 teev. Txias rau hauv chav sov, acidify nrog concentrated hydrochloric acid rau pH 2, cia sawv ntsug, lim, ntxuav nrog dej, ntxuav nrog sodium hydroxide tov rau pH=8 - 9, ntxiv crystalline sodium acetate thiab glacial acetic acid, cia sawv ntsug, thiab lim. tawm 2-Methoxybenzoic Acid.
