NON-AQUEOUS FLUID MARKER CONTAINING N-BENZYL-N-ETHYLANILINE AND METHOD FOR PREPARING THE SAME

摘要

The present invention provides an azo dye which can be used as a marker for a non-aqueous fluid product containing N-benzyl-N-ethylaniline, and a method for preparing the same. The marker containing N-benzyl-N-ethylaniline according to the present invention exhibits high solubility in non-aqueous fluid products, has excellent storage stability, can be detected even in a small amount, and can exhibit a distinct color by reaction with an acid developer in the non-aqueous fluid product. Therefore, when the marker is added to a non-aqueous fluid product, the product can be easily distinguished from other companies' products containing no marker, which makes it possible to easily control the quality of the non-aqueous fluid product in the distribution process.
