描述

一般說明

Acetic acid is an organic acid mainly used as a preservative, acidulating agent and flavoring agent.[1][2] It is one of the main volatile constituents of vinegar and pyroligneous acid.[3] Acetic acid is used as a flavoring agent in ice-creams, nonalcoholic beverages and baked goods.[4] It is also used as a chemical reagent for the synthesis of vinyl acetate monomer, cellulose acetate, acetic anhydride, acetate ester, and terephthalic acid.[5]

應用

Acetic acid can be used as a mobile phase additive to improve the separation and resolution of the bioactive compounds on the C18 column in reverse phase HPLC.[6] It is also used as an analytical reference standard in chromatographic applications.
