[0129] Material

[0130] The ethanol, sulfuric acid, sodium hydroxide solution and also the solvents used for the analysis were from Merck and were used without prior purification. High performance liquid chromatography (HPLC) was performed using an Agilent 1260 analytical chain with a C18 column.

[0131] After treatment of the aqueous phase produced by the fermentation of ferulic acid by the microorganisms, a composition (C) comprising natural vanillin, vanillyl alcohol and solvent S1 is obtained. The cultivation of the microorganisms was carried out according to the conditions described in EP 0 885 968 and the solvent S1 corresponds to ethyl acetate. Composition (C) was analyzed by HPLC, and the results are presented in Table 1.

[0132] In step (i), 349.5 g of composition (C), 21 g of ethanol (ROH) and 0.5 g of 96% H 2 SO 4 introduced into the reactor. The mixture was stirred at room temperature for 1 hour to form a compound of formula I, wherein R=ethyl, n=0. A comp...

Abstract

The present invention relates to a method for treating a composition comprising natural vanillin by isolating a compound of formula (I).

Description

[0001] This application claims priority from patent application number 1908644 filed in France on July 30, 2019, the content of which is incorporated by reference in its entirety. technical field [0002] The present invention relates to a process for treating a composition comprising natural vanillin by isolating a compound of formula (I). Background technique [0003] Vanillin or 4-hydroxy-3-methoxybenzaldehyde can be obtained by various methods known to those skilled in the art, in particular by the following three routes: [0004] - A "natural" approach based on a biotechnological process, which in particular consists in the cultivation of microorganisms capable of bioconverting the fermentation substrate into vanillin. Such a process in which the fermentation substrate is ferulic acid is known in particular from application EP 0 885 968 . The ferulic acid used can be derived from various sources, in particular derived from rice bran or corn bran. The result of these p...
