Eugenol / ˈ j uː dʒ ɪ n ɒ l / is an allyl chain-substituted guaiacol, a member of the allylbenzene class of chemical compounds. It is a colorless to pale yellow, aromatic oily liquid extracted from certain essential oils especially from clove oil, nutmeg, cinnamon, basil and bay leaf. The present invention is process of synthesizing guaiacol with catechol and dimethyl carbonate as materials. The process includes the steps of heating catechol and phase transfer catalyst to 100-150 deg.c to reach smelting state, adding quantitative alkaline catalyst, heating the mixture to 110-190 deg.c, dropping dimethyl carbonate quantitatively in the molar ratio to catechol of 1.0-2.0 to 1 2000-07-18 · Oral/Parenteral Toxicity: intraperitoneal-mouse LD50 320 mg/kg oral-mouse LD50 312 mg/kg oral-rat LD50 597 mg/kg oral-mammal (species unspecified) LD50 597 mg/kg Gigiena i Sanitariya.

Guaiacol toxicity

Guaiacol is a compound used as expectorant. In Mexico City, this product is being illegally used for aesthetic treatment with fatal results. The aim of this study is to confirm the lethal toxicity documented in humans. toxicity of guaiacol was carry out at six doses of pure guaiacol (6.25, 12.5, 25, 50, 100 and 200 μl, by subcutaneous route); six to seven mice by dose.

In wastewater, NO 2 addition reactions lead to higher toxicity of products (nitroguaiacols and 2-methoxybenzene-1, 4-diol) than that of parental guaiacol. However, O 2 /NO addition pathways may generate less harmful products except for methoxybenzoquinone (P3) which is with higher toxicity than guaiacol.

The antiinflammatory, analgesic and antipyretic activities of these derivatives were evaluated, together with their antioxidant, mucolytic and broncho-bacteriostatic properties in comparison to acetylsalicylic acid. In recent years, of the roughly 18,000 metric tons of vanilla flavor produced annually, about 85% is vanillin synthesized from the petrochemical precursor guaiacol. Most of the rest is from lignin. 2-Methoxy-4-methylphenol (Methyl guaiacol) Kreosol [German] FEMA No. 2671. EINECS 202-252-9. BRN 1862340.

9 Mar 2015 It is shown that only after the primary pollutant guaiacol has been consumed, its probably most toxic nitroaromatic product is largely formed. Of the compounds developed in this study the most effective were: Tetrabrom-o- cresol, which has but little toxicity yet inhibits growth of diph- theria bacilli diluted to  The enzymes guaiacol peroxidase (GPX) and catalase (CAT) activities increased in both the plants and were higher in V. faba. A positive correlation between  13 May 2020 Lead toxicity resulted in increased level of the guaiacol peroxidase activity in both cultivars.
