3-메틸-4-(2,6,6-트라이메틸-2-사이클로헥센-1-일)-3-뷰텐-2-온 C화학적 특성, 용도, 생산
개요
α-Isomethylionone has a fine violet and orris-like odor. This substance may be synthesized by condensation of citral with methyl
ethyl ketone controlling the ratio between the n- and iso-forms;
the methyl pseudo-ionone obtained is then subjected to ring closure, using strong alkali and high temperature (thus favoring the
formation of the normal α- and β-methylionones) or with quaternary ammonium base (thus favoring the formation of wo-forms);
See also monographs of α- and β-ionone and methyl α-, β-, and
γ-ionones.
