METHOD OF PRODUCING DIAMANTANE (PENTACYCLO[7.3.1.1.0.0]TETRADECANE) Russian patent published in 2012 - IPC C07C13/615 C07C5/31 B01J29/08

Abstract RU 2459794 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing diamantane (pentacyclo[7,3,1,1^4,12,0^2,7,0^6,11]tetradecane) of formula (1) through isomerisation of tetrahydrobinor-S. The method is characterised by that the reaction is carried out in the presence of a zeolite Y catalyst in NaH form with ion-exchange degree of 40-60%, first subjected to heat treatment at 450°C for 3-5 hours in air, in amount of 30-70 wt % at reaction temperature 270-300°C for 15-30 hours.

EFFECT: present method uses a cheap catalyst and enables to avoid corrosion and simplifies implementation.
