Do u have a picture of ftalat and tereftalat acid??

Question

and if possible give me a site which teach us how to make perfume.... especially perfume from acethaldehydes

Answer 1

In English, these are Phthalic acid (Benzene-1,2-dicarboxylic acid) and Terephthalic acid (Benzene-1,4-dicarboxylic acid).

There are far too many compounds used in the perfume industry which start with acetaldehyde to give examples or site here. I suggest you go to the local library and pick up a primer on perfumes.
