1-UNDECANOL Usage And Synthesis
Background 1-undecanol, being an organic chemical with molecular formula C11H24O and scented with lemon, is a colorless or pale yellow , water insoluble but alcohol and ether soluble liquid. It is prepared from metal sodium reduction of Ethyl undecanoate, or pressurization and catalytic hydrogenation of ethyl ω- undecanoate , or even obtained by the Grignard reaction of nonyl magnesium bromide and with ethylene oxide. The application of this alcohol is limited. It is only used for some typical aroma oil and fragrance as the fat is solid at low temperature. The citrus rose type and the like only play a secondary and harmonious role and are taken as deodorant. In addition, it is also used to manufacture spices with the scent of acacia, polianthes tuberosa and the like.
Chemical Properties It is colorless liquid at room temperature; scented with light sweet fat wax mixed with the scent of roses and fruity flavor of citrus, pineapple and the like. But generally the whole body smells scent of rose, as if a little bit of rue flavor. It will smell like orange after highly diluted with the soft sweet flavor of citrus fruit oil. Its concentration is less than 20 × 10-6 with fruity and sweet scent. Unpleasant fat and smell will be produced when the concentration is higher; Melting point :15 ~ 19 ℃; Flash point> 82 ℃; Density: D4250 .828 ~ 0.834; Refractive index: nD200.4370 ~ 1.4430; water insoluble, soluble in most organic solvents, 1: 4.soluble in 60% ethanol
