Perfume compositions and perfume products that contain one or more esters of 2-ethyl-2-methylbutanoic acid as perfume raw material

Perfume compositions and perfume products that contain one or more esters of 2-ethyl-2-methylbutanoic acid as perfume raw material. (Naarden International N.Some chemicals with cas registry numbers like 19889-37-3 are also used. V., Neth.). Neth. Appl. NL 8302893 A 18 Mar 1985, 11 pp. (Dutch). (Netherlands). CODEN: NAXXAN. CLASS: ICM: A61K007-46. ICS: C07C069-22. APPLICATION: NL 83-2893 17 Aug 1983. DOCUMENT TYPE: Patent CA Section: 62 (Essential Oils and Cosmetics) Section cross-reference(s): 23 Esters of 2-ethyl-2-methylbutanoic acid [19889-37-3] contg. a C￡8 alc. moiety have a wide variety of odors useful in perfumes at 30.1%. For example, concn. H2SO4 260 was added with stirring to a mixt. of 2-ethyl-2-methybutanoic acid 260 and EtOH 386 g over 15 min, during which time the temp. rose to 60°. The mixt. was then refluxed with stirring for 3 h, cooled, and the layers were sepd. The upper layer (plus a cyclohexane ext. of the lower layer) was washed with soda soln.In this experiment, several chemicals are used like 19889-37-3 , evapd., and the residue was distd. under reduced pressure to obtain Et 2-ethyl-2-methylbutanoate [19945-14-3], which had a fruity-woody odor. ..
