The resulting allyl ester is obtained rapidly in high yield with a minimal level of catalyst. In addition, product isolation is simple, and color is exceptionally low. The process is particularly valuable for making diallyl phthalate from dialkyl esters of phthalic acid. 展开 ...

Additionally, fatty acids are precursors for the production of other volatile compounds (fatty acid esters; ethyl esters are more common in cheese, thioesters, fatty acid lactones, and methyl ketones) during ripening (Guinee et al., 20041). Proteolysis is the most complex, in most cheese ...
In the visual cycle, RPE65 serves as the isomerase that converts all-trans-retinyl esters to 11-cis-retinol (136, 137, 138). The absence of RPE65 results in a failure to produce the 11-cis-retinal chromophore, so all-trans-retinal, which is the essential precursor for bisretinoid ...
hydrocolloids are contingent on their high water-binding capacity and interactions with dough structural components, e.g., gluten proteins and starch. Emulsifiers, such as sodium stearoyl-2-lactylate (SSL), diacetyl tartaric acid esters of monodiglycerides (DATEM), and lecithin (LC), function as ...

Alcohols of formula (F) are useful as, among other things, ingredients in lubricants, ointments, and shampoos and as intermediates for preparing carboxylic esters useful in perfumery and flavors. Additional non-limiting embodiments are described below. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows...
The solvent could be water, chloroalkane like dichloromethane, chloroform, dichloroethane, chlorobenzene, hydrocarbon aromatics like benzene, toluene, xylene, aliphatic hydrocarbons like cyclohexane, n-hexane, n-heptane, esters like ethylacetate, nitriles like acetonitrile or dimethylsulfoxide and preferably...
Examples of useful protecting groups for acids are substituted alkyl esters such as 9-fluorenylmethyl, methoxymethyl, methylthiomethyl, tetrahydropyranyl, tetrahydrofuranyl, methoxyethoxymethyl, 2-(trimethylsilyl)ethoxymethyl, benzyloxymethyl, pivaloyloxymethyl, phenylacetoxymethyl, triisopropropylsysilylmeth...
