▎ 摘　　要

NOVELTY - A synthetic alkylated graphene comprises a pericondensed aromatic core with 4-12 aromatic rings substituted with 1-2 linear alkyl chains containing 5-12C atoms, having a molecular mass of 300-800 g/mol. Proportion of aliphatic carbon atoms is 30-60 % of the total number of carbon atoms in the molecule. USE - Synthetic alkylated graphene for use in mixtures used as multiphase flow test fluids, in separation tests and in oil and gas industry (claimed). ADVANTAGE - The compound gives the operator more readily available tools to assess multiphase flow and to compare such flows during production and between different wells. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for mixtures of above compounds dissolved in aromatic or aliphatic base oils or their mixtures.
