Спосіб отримання
Florol is a synthetic molecule made by chemical synthesis. Cyclocondensation of 3-methyl-3-buten-1-ol with 3-methylbutanal on silica gel and alumina, without solvent, is proposed for its synthesis. In one preparation, an acetal was stirred with 5% phosphoric acid at 60 °C for 6 hours, and the reaction was stopped when the acetal content fell below 1%. The material was washed with 5% sodium hydroxide solution until the aqueous phase was weakly alkaline, then distilled, giving 2-isobutyl-4-hydroxy-4-methyltetrahydropyran with a GC content of 97% and a yield of 82%.

У парфумерії
Florol can be used in almost all perfume types, where it gives elegant floral diffusion without changing the character of the fragrance. It is a very stable and substantive building block that can also replace less stable floral aldehydes. In fine fragrance it is listed as a top and heart note. It is stable in perfumes, face creams, talcum powders and other daily chemical products. Its recommended applications include shampoo, shower gel, soap, detergent and softener.
