These are different compounds : de l'ester 3-... de l'acide acétique (26,32 g), du Pd/Al2O3 à 10 % (12,93 g) et de l'acétate d'ethyle
Be careful, choromène is different from chromane (in the first cas, it should be translated in the compound as "chromén-7-yl"

Using an article with a compound Having 2 compounds like "Acetic acid 3-(4-hydroxy-phenyl)-8-methyl-4-oxo-4H-chromen-7-yl ester and ethyl acetate" in a same sentence.
Do you use the same article for both or not?, meaning « 3-(4-hydroxy-phényl)-8-méthyl-4-oxo-4H-chromen-7-yl ester de l'acide acétique (26.32g), 10% Pd/Al2O3 (12.93 g, 50 %) et de l'acétate d'éthyle » or « du 3-(4-hydroxy-phényl)-8-méthyl-4-oxo-4H-chromen-7-yl ester de l'acide acétique (26.32g), 10% Pd/Al2O3 (12.93 g, 50 %) et de l'acétate d'éthyle »

It looks like a typo to me. And you can suppress the "-" between oxo and chroman and between hydroxy and phenyl

Paul Patruno (asker) Aug 22, 2014:

"8Acetic acid 3-(4-hydroxy-phenyl)-8-methyl-4-oxo-chroman-7-yl ester" would then be « 3-(4-hydroxy-phényl)-8-méthyl-4-oxo-chroman-7-yl ester de 8-acide acétique » or « 8 » is a typo
