Air fresheners containing cyclohexyl alkyl ketones

Air fresheners containing cyclohexyl alkyl ketones. Schleppnik, Alfred Adolf (Monsanto Co., USA). Ger. Offen. DE 2756050 29 Jun 1978, 26 pp.Several substances are used for example 823-76-7 which is its cas registry number. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07C049-43. PRIORITY: US 76-751773 16 Dec 1976. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 24 Cyclohexyl alkyl ketones (I; R2,R3,R4 = H or C1-4 lower alkyl such that R2 + R3 + R4 ￡C5, R1 = C1-4 alkyl) are prepd. 823-76-7 which is the cas registry number is also used here. and used in air freshener aerosols with perfume bases. For example, cyclohexyl Me ketone (II) [823-76-7] was prepd. by hydrogenation of acetophenone [98-86-2] and oxidn. of the resultant 1-cyclohexylethanol [1193-81-3]. When used at 260 mg/m3 to counteract a synthetic bathroom odor (267 mg/m3) a compn. comprising 0.45% cologne, 0.05% cyclohexyl Me ketone, 49.75% CCl3F and 49.75% CCl2F2 gave a very fresh, much weakened residual odor. ..
