CUMULENE SUBSTANCE, METHOD FOR PRODUCING THEREOF AND USE THEREOF Russian patent published in 2018 - IPC C07C209/62 C07C211/22 C07C215/24 B82B1/00 C23C14/12 B01F17/16 B01F17/46 

FIELD: chemistry.

SUBSTANCE: invention relates to a novel cumulene substance comprising a chain of cumulated carbon-carbon double bonds and amino groups as "end groups", as well as optionally hydroxyl groups, obtained by the new method as described below. Cumulene substance can be used as a surfactant and for the production of nitrogen-containing carbon films. Method for producing a new cumulene substance consists in polycondensation of hexamethylenetetramine in anhydrous sulfuric acid in two stages – in the first stage, the components are mixed in a mode that does not allow overheating the reaction mixture above 90 °C, in the second stage, the resultant reaction mixture is heated within a temperature range of 100–120 °C, followed by the addition of water and an aqueous ammonia solution to the resultant reaction mass and isolating the product. Invention also relates to the use of the cumulene substance for producing nitrogen-containing carbon films by applying an acetic acid solution of said cumulene substance to a substrate, followed by drying and heat treatment of the obtained layer. Inventive cumulene substance can also be used for dispersing and exfoliating graphite materials.

EFFECT: introduction of amino groups into the cumulene substance allows increasing its solubility in water and thereby simplifies the use of the substance.
