The invention relates to cyclic dioles. in particular, the preparation of cyclic diols of a cyclohexane or bicycloheptane row of a common f-ly Rj-C (OH) -CR2COH) ~ n-Rj, -CH-CHj-GMRj-Ctt-tHi where n-R3 = -CHF? HGH2) 2-CH2 - or Ri, R2.R3 = H or CH3. stabilizers used in the manufacture of antioxidants. perfumes. The goal is to simplify the process, reducing the consumption of reagents and catalyst. For this purpose, hydroxylation of cycloolefinic hydrocarbons with hydrogen peroxide in the presence of molybdenum oxobromide and acetic acid is carried out at a molar ratio of 1 < 1-1.1): [ |
