Abstract RU 2035448 C1

FIELD: organic chemistry. SUBSTANCE: product: 2-acetonyl-5,5-dimethyl-1,2,3,4,5,6,7,8-octahydronaphthalene, empirical formula is C₁₅H₂₄O, b. p. is 100-102 C. Reagent 1 is synthesized by condensation of linalool with vinylbutyl ether under atmospheric pressure and boiling point of mixture in the presence of mixture of phosphoric and acetic acid at their mass ratio 1: (1.2-1.3) following by crotonic condensation of prepared 2,6-dimethyl-2,6-decadienal-10 with acetone at 170-175 C in the presence of zinc acetate or its dihydrate taken at concentration 15-20% of aldehyde mass. EFFECT: improved method of synthesis. 4 cl, 1 tbl
