It is a pre-cursor to manufacturing APIs for cough syrup and various flavors such as Eugenol and Vanillin. (cleanscience.co.in)
Compounds3
pyrolysis of the bagasse lignins yields compounds including guaiacol, 4-methylguaiacol and 4-vinylguaiacol. (wikipedia.org)
Guaiacol is a useful precursor for the synthesis of other compounds. (wikipedia.org)
Regardless of the wood type, volatile compounds were mainly methoxyphenols, with the highest contribution from eugenol, followed by guaiacol and their corresponding derivatives. (mun.ca)
Clove2
EUGENOL The tom clancy's rainbow six siege no recoil undetected free compound with chemical formula C10H12O2, an allyl chain- substitute d guaiacol of the phenylpropanoid s, found in essential oil s such as clove, nutmeg, and cinnamon. (xinmeitulu.com)
This standard applies to food additives eugenol, which is prepared by chemical isolation, using clove basil oil and bay leaf oil as raw materials AND by chemical synthesis, using guaiacol and allyl chloride as raw materials. (chinesestandard.net)
Glyoxylic acid2
The route entails the condensation reaction of glyoxylic acid with guaiacol to give mandelic acid, which is oxidized to produce phenylglyoxylic acid. (wikipedia.org)
most popular method today is the two-step process practiced by Rhodia (from 1970s onwards), in which guaiacol reacts with glyoxylic acid by electrophilic aromatic substitution. (blogspot.com)
