Abstract SU 1840617 A1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to a method for synthesis of pinacolin. Method involves using reagent 1 comprising 2-methylbytane or product of its hydrochlorination, or their mixture, and reagent 2 comprising formaldehyde and hydrochloric acid an aqueous solution. Reaction is carried out in the ratio 2-methylbutane to hydrochloric acid = 1:(3-3.5), and the process is carried out in the presence of a surface-active substance, for example, OP-7.
