NOVEL FORM OF HYDROQUINONE AND SYNTHESIS METHOD THEREOF Russian patent published in 2012 - IPC C07C39/08 C07C37/84 C07C37/74 C07C46/10 B01J2/24 

FIELD: chemistry.

SUBSTANCE: invention relates to a novel form of hydroquinone, characterised by that it has the form of flakes - dense particles, having the shape of plates, characterised by that the flakes have length which varies from 0.5 to 6 cm and width which varies from 0.5 to 3 cm. The invention also relates to use of said flakes as an intermediate product for producing hydroquinone in form of isotropic particles, as well as a method of producing said flakes. The method involves the following steps: if necessary, spraying hydroquinone powder, depositing hydroquinone in liquid state in form of a film onto a substrate made from material or coated with a material which conducts heat, solidifying the hydroquinone by bringing the substrate to a suitable temperature and collecting the solidified product in form of flakes using any suitable means.

EFFECT: use of the novel form of hydroquinone enables to solve dust and cleaning problems arising during production of hydroquinone.
