Abstract
Procedure for the synthesis of 2,6-dihydroxyzineol, characterized in that it comprises the following phases from pure overrol, through a pure pinol: A) Pinol epoxide (1: 2: 6: 8-diepoxy-p) is obtained -methane) at 98%, and B) the latter is subjected, as obtained, that is, with about 98%, to hydrolysis, in an aqueous or hydroalcoholic environment, with an acid chosen from among mineral acids, such as hydrochloric, sulfuric, phosphoric and organic acids, such as acetic, tartaric, malic, citric, at a concentration that can vary from traces, suitable for conceiving a pH between 5 and 0.5, at values of 1 - 2%, at a temperature between 10 and 125ºC, depending on the solvent used, at normal pressure and for 6-24 hours; the aqueous (or hydroalcoholic solution obtained) is subjected to salification and extraction with an organic solvent, chosen from ether, chloroform, methylene chloride, and finally the extract is subjected to evaporation and crystallization to isolate 2,6-dihydroxicineol; and characterized by the fact that it operates on an industrial scale.
