The present invention relates to a method of production of a paper fibre composition, comprising the steps of: a) Providing a vessel, b) Providing Na2S03 in the range of 12-122 kg/bdt combined with NaOH in the range of 0-97 kg/bdt, or NaHSO3 in the range of 10-100 kg/bdt combined with NaOH in the range of 10-100 kg/bdt to said vessel, c) Providing wood, preferably softwood chips to said vessel for pre-treatment, d) Providing heat and pressure to said vessel in order be able control the vessel to have a temperature T comprised in the range of 160 °C - 184 °C, e) Controlling the retention time t for the wood chips, in relation to the temperature T of the content of the vessel, wherein T is controlled to be within the range of step d) and t is controlled to be in the range of 2-27 min, preferably in the range of 2-25 min, more preferred in the range of 5-20 min,: f) Providing a defibration device coupled to the outlet of said vessel, the defibriation device being a refiner, mill, defibrator, fiberizer, or the like, g) Providing the pre-treated wood chips to the defibration device, h) Providing an energy consumption of 75-1000 kWh/bdt in said defibration device. The invention also relates to a paper fibre composition prepared by the method and a paper or paperboard or molded pulp made from the paper fibre composition.
The present invention relates to a method for production of p-cymene from cyclic monoterpenes in the presence of an Fe(III)-salt as a catalyst. In particular it relates to a method for production of p-cymene from cyclic monoterpenes containing high levels of sulphur, such as crude sulphate turpentine. The method can be performed as two different, subsequent processes for the isomerization and oxidation reactions, or in a single process wherein these reactions take place at the same time.
C07C 5/367 - Formation of an aromatic six-membered ring from an existing six-membered ring, e.g. dehydrogenation of ethylcyclohexane to ethylbenzene
C07C 5/387 - Preparation of hydrocarbons from hydrocarbons containing the same number of carbon atoms by dehydrogenation with formation of free hydrogen with simultaneous isomerisation of cyclic compounds containing no six-membered ring to compounds containing a six-membered aromatic ring
The invention relates to a method of isolating cymene comprising the following steps: a) providing a solution comprising cymene and monoterpenes, b) adding sulphuric acid to the solution in a) such that the concentration of sulphuric acid in the solution is at least 0.5 % (w/w), such as 1-25% (w/w), c) distilling the solution mixture from step b) such that a target chemical stream enriched in cymene is obtained and separated from a residual stream.
The present invention relates to a method for production of cymene comprising the following steps: a) providing a solution comprising cyclic monoterpenes having the formula C10H16 b) addition of a catalyst comprising Fe3+ and/ or Fe2+ ions c) addition of sulphur dioxide to the solution d) incubation of the solution mixture from step c) for a reaction time at a reaction temperature such that at least part of the cyclic monoterpenes are converted to cymene such that a solution comprising cymene is obtained.
