Pinacol Chemical Properties,Usage,Production

  • Chemical Properties white solid
  • Occurrence Has apparently not been reported to occur in nature.
  • Uses pinacol be used as organic intermediates.
    The pinacol coupling reaction with the inorganic electride [Ca2N](+)·e(−) as an electron donor in organic solvents was studied.
  • Preparation By the bimolecular reduction of acetone.
  • Definition ChEBI: A glycol that is ethylene glycol in which all four methylene hydrogens have been replaced by methyl groups.
  • Toxicity evaluation Both the acute oral LD50 value in rats and the acute dermal LD50 value in rabbits exceeded 5 g/kg (Moreno, 1975). The acute oral LD50 of pinacol for male albino mice was found to be 28-6 mmol/kg (Wenzel & Koff, 1956). Pinacol showed anticonvulsant activity for electroshock seizures and Metrazol? convulsions; the PD 50 values (a measure of the protective dose) determined 15 min after oral administration of pinacol to mice were found to be 16-4 and 3-44 mmol/kg for electroshock and Metrazol convulsions, respectively (Wenzel & Koff, 1956).
  • Metabolism Pinacol forms a glucuronide in the rabbit (Williams, 1959), and was found highly conjugated with glucuronic acid in the urine of chinchilla rabbits following oral administration of 1.0-1.5 g pinacol/kg body weight (Gessner, Parke & Williams, 1960). Pinacol was not utilized to any significant extent by endocrine tissues from human placenta, rat ovary, rat testis or rat adrenal gland (Ferguson, Baillie, Caiman & Hart, 1966).
  • Purification Methods The hydrate is rendered anhydrous by azeotropic distillation of water with *benzene. Recrystallise it from *benzene or toluene/pet ether, absolute EtOH or dry diethyl ether. It recrystallises from water to give the hexahydrate. [Beilstein 1 IV 2575.]
