    Abstract: Alkyne cleaning involves utilizing a solvent, to which a polymerization inhibitor is added. The polymerization inhibitor is selected from N-oxylene, secondary amine or their mixture. The solvent is selected from N-alkyl substituted pyrrolidone, dimethylformamide, dimethylacetamide, lactone, alcohol, mineral oils, water, alkaline solutions, alkane or their mixture. The N-oxylene has general formula (I), and secondary amine has general formula (II). n,m : 0, 1, 2, 3, 4 or 5; R 1>, R 2>, R', R'', R 5>-R 10>H, 1-8C-alkyl, 3-8C-cycloalkyl, 3-8C-heterocycle, 2-8C-alkenyl, 2-8C-alkinyl, 5-16C-aryl, 5-16C-heteroaryl or functional group selected from=O, -NHR 11>, -N(R 11>) 2, -SR 11>, -OR 11>, -CHO, -C(=O)R 11>, -COOR 11>, -OC(=O)R 11>or -NHC(=O)R 11>, where R 11>=H, 1-8C-alkyl, 3-8C-cycloalkyl, 3-8C-heterocycle, 2-8C-alkenyl, 2-8C-alkinyl, 5-16C-aryl or 5-15C-heteroaryl, where the aryl and heteroaryl groups are bonded via a carbon bridge with 1-8C or heteroatom; and R 13>, R 14>, R, R''', R 17>-R 23>H, 1-8C-alkyl, 3-8C-cycloalkyl, 3-8C-heterocycle, 2-8C-alkenyl, 2-8C-alkinyl, 5-16C-aryl, 5-16C-heteroaryl or a functional group selected from=O, -NHR 24>, -N(R 24>) 2, -SR 24>, -OR 24>, -CHO, -C(=O)R 24>, -COOR 24>, -OC(=O)R 24>or -NHC(=O)R 24>, where R 24>=same as variable group of R 11>. Provided that: (A) one of R 1>, R 2>, R', R'', R 5>-R 10>of two different molecules of formula (I) forms a saturated or unsaturated, branched or normal carbon bridge with 2-20 atoms between these two molecules, where carbon bridge contains hetero atom selected from N, O, P or S, and if necessary a functional group selected from -NHR 12>, -N(R 12>) 2, -SR 12>, -OR 12>or=O, where R 12>=same as variable group of R 11>. An independent claim is included for a mixture, which contains a solvent and a polymerization inhibitor. [Image] [Image].

    Abstract: The method comprises introducing raw materials needed for thermal partial oxidation into a reactor (1) and mixing in a mixing zone, and supplying the mixture by a diffuser into a burner block (15) provided with channels (2). The mixture flowing through the channels forms a turbulent flow field by turbulence generators arranged in the channels due to the predetermined deflection of flow direction. The turbulence generators are inserted in all channels and are arranged in such a manner that it forms an alternative rotational direction during the flow of the material through the channels. The method comprises introducing raw materials needed for thermal partial oxidation into a reactor (1) and mixing in a mixing zone, and supplying the mixture by a diffuser into a burner block (15) provided with channels (2). The mixture flowing through the channels forms a turbulent flow field by turbulence generators arranged in the channels due to the predetermined deflection of flow direction. The turbulence generators are inserted in all channels and are arranged in such a manner that it forms an alternative rotational direction during the flow of the material through the channels related to neighboring channels. Auxiliary flames (14) used for flame stabilization are generated at a distance of 4-15 times of the channel diameter from the lower edge of the burner block measured in a combustion chamber (4). An independent claim is included for a device for the thermal partial oxidation of hydrocarbons in a reactor for producing acetylene and synthesis gas.
