Aproximativ 85% din producția mondială de vanilină se realizează plecând de la guaiacol. Metoda începe cu o reacție de condensare a acidului glioxilic cu guaiacolul (1), obținându-se acidul vanilmandelic (2), care se oxidează la un derivat de acid acid fenilglioxilic (3).

Since it is produced in soft drinks and juices by contaminant yeast and moulds, other metabolites (such as styrene) may also be formed. CAS registry number The CAS registry number for 4-vinyl guaiacol is 7786-61-0.

An alternative method of synthesis involves treating guaiacol directly with an equimolar amount of glycerol α-monochlorohydrin in a strongly alkaline solution or suspension (Scheme 2). When the vigorous reaction subsides, the mixture is heated for three hours, concentrated in vacuo, and extracted with hot isopropanol to yield (after filtration and cooling) product in greater than 80% yield.

The global reaction catalyzed by POD in the pres-ence of guaiacol is shown in Scheme 1. Beyond its importance in biochemistry, POD has sev-eral applications in many ﬁelds [19]. PODs are broadly wsAdditional Supporting Information may be found in the online version of this Here, you will find the best quality guaiacol that relaxes you. You can place these fascinating guaiacol at any place, may it be your bedroom, living room, workplace, etc. At Alibaba.com you will find a huge range of different kinds of guaiacol at very reasonable prices. Guaiacol (/ ˈ ɡ w aɪ ə k ɒ l /) is a naturally-occurring organic compound with the formula C 6 H 4 (OH)(OCH 3).

guaiacol in the presence of Al3+ indicated that there might be diﬀerent binding modes between guaiacol and Al3+. The multiple interactions between Al3+ and guaiacol in the presence of Al−O and Al···H were investigated by in situ Fourier transform infrared spectroscopy, and they inhibited the production of the double condensation
