Ethyl acetate menthol

Standnikow has prepared several of the esters of menthol by heating magnesium iodo-mentholate with the esters of ethyl alcohol. For example, with ethyl acetate, propionate, and benzoate the corresponding menthyl esters were obtained. These bodies have the following boiling-points —... 

S,3//,4/C6//)-carane-3,4-diol with (l/ )-tra s-chrysanthemic acid is 0.62, and the Rf. value of the corresponding ( l,S )-/ra .v-chrysanthemic acid ester is 0.65 (toluene ethyl acetate = 3 1). However, the /-menthol ester of (1 /. S )-/ra .v-chrysanthemic acid could not easily be separated by silica gel column chromatography to obtain (1 AfWran.v-chrysanthemic acid /-menthol ester. 

Thin layer chromatograms were obtained with silica gel as absorbent and ethyl acetate as developing solvent. The order of elution and Rf values of the major components are as follows menthyl sulfinate (0.65), menthol (0.59), sulfinyl ketal (0.30). 

The model tests were carried out both iso-thermally (i.e. at constant temperature) and in temperature gradients (from warm to cold). Alcohols (e.g. ethanol, hexanol, octa-nol, decanol), aldehydes (e.g. decanal), ketones (e.g. diacetyl), acids (e.g. caproic acid), esters (e.g. ethyl acetate), terpenes (e.g. menthol, menthone, 6-pinene, limonene), amines (e.g. butyl amine), pyrazines and other classes of substances have been investigated as flavouring substances [6,9,11,13-18].

Some of the denaturants in laboratory use ethanol are cyclohexane (1%) isopropyl alcohol ( 5%) diethyl phthalate (1%) toluene (1-2%) 2-butanone (methyl ethyl ketone) (2%) a mixture of 2-butanone and 4-methyl-2-pentanone (methyl isobutyl ketone) (2% and 0.5%, respectively) methanol (5%), designated SDA Formula 3 ethyl acetate and gasoline (5% and 1%, respectively), designated SDA Formula 1 ethyl acetate, 4-methyl-2-poitanone, and gasoline (each at 1%), designated SDA Formula 1-1 ethyl acetate and methanol (1-2% and 3-5%, respectively) 4-methyl-2-pentanone and ko osene (4% and 1%, respectively), designated Formula CDA 19 and isopropyl alcohol and methanol (5% each). Note that many other denatured ethanols (e.g., bitrex and menthol denatured) are available, typically for use in personal care and cosmetic products. 

The number of investigations on the enantioselective dipolar cycloaddition of nitronates is still rather limited. In the case of simple alkyl nitronates, the facial selectivity is controlled solely by the steric environment about the two faces of the chiral unit. For example, the reaction of steroid dipolarophile 270 proceeds with the nitronate approaching the Re face of the alkene (Eq. 2.23) (234). The facial selectivity is controlled by the C(19) methyl group, which blocks the Si face of the dipolarophile. Similarly, exposure of 279 to ethyl acrylate at 40 °C for 24 h, provides a single nitroso acetal (Scheme 2.21) (242). The facial selectivity is presumed to arise from steric shielding by the menthol group, however the full stereostructure has not been established. 

America, and Japan. The main constituents of the essential oil are a- and p-pinene, limonene, cineol, ethyl amylcarbinol, menthone, menthol, isomenthol, menthyl acetate, and piperitone. It has a strong mint odor with a sweet balsam taste masked by a strong cooling effect. It is widely used in foods, as well as in liquid pharmaceuticals, to 8000 ppm.
