ORGANIC COMPOUNDS NANOPOWDERS, METHODS FOR PRODUCTION THEREOF AND SUSPENSION THEREOF Russian patent published in 2017 - IPC A61K9/14 B02C17/20 B02C23/06 

FIELD: chemistry.

SUBSTANCE: invention is a method for producing organic compound nanopowder comprising: mixing of the granular organic compound, granular carbohydrate compound containing at least one of granular saccharide and granular sugar alcohol of 0.3-fold or more quantity by mass relative to the amount of organic compound and liquid where the organic compound is not soluble or is poorly soluble in a mixer; wet milling of organic compound using granular carbohydrate compound as a milling agent after mixing so that the average diameter of the organic compound particles after milling is 500 nm or less and the 90% diameter is less than 1500 nm. Wet milling of organic compound is carried out while stirring the mixture obtained after mixing in the mixer.

EFFECT: implementation of the invention simplifies the process of fine milling of organic compounds due to reducing or eliminating the need to use milling agents and other additives to be removed from the produced nanopowders.
