“…The concentrations of linalyl acetate determined in this study are in accordance with those in other reports in the literature on Italian bergamot oil, but lower than those in Turkish bergamot; results for geranyl acetate and neryl acetate were higher than those reported in the same studies …”

“…Nerol is an important compound for aroma because it gives the sour citrusy flavour. Linalool concentration was is in line with that in some previous studies and higher than in others; α‐terpineol and nerol concentrations in this study were higher than those reported in the literature . Earlier reports showed that a lower linalool concentration corresponded to a higher limonene concentration; in our study a similar response was observed at the last harvesting time; however, the effect of sampling time was not significant.…”

“…Decanal increased from first to third harvest; the values measured at the second sampling time were intermediate and not different from H1 and H3 (Table ). Several authors investigated aldehyde concentrations in bergamot oil; all of them found values lower than those reported in this study.…”

“…Limonene and β‐pinene concentrations measured in the present experiment were slightly lower than those reported in the literature; while ( Z )‐β‐ocimene and β‐mircene concentrations were higher than in previous reports . In a study by Kirbaşlar et al on Turkish bergamot oil, a lower concentration of limonene (23.7%) and a similar concentration of β‐pinene (3%) were found, compared to our experiment.…”

Bergamot (Citrus × bergamia) is mainly cultivated in Calabria area (Italy) for its essential oil that is widely used in cosmetics, food and medicine. The harvest season (November to February) affects the quality of essential oil, consequently the aim of our study was to evaluate the composition of volatile fractions at different harvesting stages. Two different cultivars, Femminello and Fantastico, were collected in November, December and January and their volatile compounds composition was determined by SPME GC/MS. Fourty‐two compounds were identified. Monoterpenes were the preponderant group; limonene was the most representative compound with similar concentrations in the varieties and at the three harvesting times. β‐Ocimene, β‐mircene and α‐terpinene showed higher concentration in Femminello than Fantastico, while trans‐α‐bergamotene, α‐pinene and citronellal were mostly concentrated in Fantastico. The concentration of β‐pinene in Fantastico and Femminello was higher in December and January, respectively, and γ‐terpinene concentration was higher in Femminello in November and January and in Fantastico in December. Linalool was the most preponderant monoterpene alcohol with a significantly higher concentration in Femminello than in Fantastico, but without significant differences during ripening. cis‐γ‐Bisabolene was the most preponderant sesquiterpene; it was more concentrated in Fantastico than in Femminello and showed a significantly higher concentration in December and January than in November. Linalyl and neryl acetate were the most abundant esters, with a significantly higher concentration in Fantastico. Fantastico seems to be the variety that produces higher volatile organic compounds in essential oil; moreover, the volatile compound concentration was higher at the second and third harvest time.

Esterification of acetic acid with methanol to produce methyl acetate in an isothermal stirred batch reactor has been studied. Sulfuric acid was used as a liquid catalyst, and Indion-180, Indion-190 and Amberlyst-16wet ion exchange resins were used as solid catalysts. The feed mole ratio was varied from 1 : 1 to 1 : 4. The reaction temperatures were varied from 305.15 to 333.15 K for sulfuric acid as catalyst and 323.15 to 353.15 K for the solid catalysts. The catalyst concentrations were used in the range of 1% to 5%, for the sulfuric acid catalyst, and 0.01 to 0.05 g/cc, for the solid catalysts. The effect of temperature, catalyst concentration, agitation speed, size of catalyst particle and reactant concentration on the acetic acid conversion was investigated. A second-order kinetic rate equation was proposed to fit the experimental data. For both forward and backward reactions, the activation energies were estimated from Arrhenius plots. The reaction rate increased with catalyst concentration and temperature for both the liquid and solid catalysts. The acetic acid conversion was found to increase with increases in acetic acid to methanol ratio in the feed. The developed kinetic rate equation was used for the simulation of reactive distillation process, in our laboratory column.

Strong-smelling plant extracts, such as essential oils, have a variety of feeding effects on mammals. Considering current concerns over long-term health issues and environmental effects of chemicals, plant-based products with repellent or antifungal activities may represent good solutions for improvement of rodent pest control programs. The present study was therefore focused on examining the effects of bergamot, lavender, and thyme essential oils as additional bait components on daily intakes of cereal-based baits by wild house mice. Lavender essential oil, containing linalool and linalyl acetate as main components, and thyme essential oil with a prevailing thymol component had no effects on house mice diet. Bergamot essential oil, whose main components were linalool, limonene, and linalyl acetate, showed a repellent effect on house mouse diet.
