摘要： The invention relates to a process for preparing tertiary alkyl ethers, in particular MTBE, ETBE or mixtures of these ethers with heavier ethers. According to the process the feedstock containing hydrocarbons is fed to a catalytic distillation reactor system, in which the isoolefines, in particular the C4 to C7 isoolefines, of the feed are reacted with an alkanol in the presence of a cation exchange resin in order to produce tertiary alkyl ether products. The reaction product containing the ethers is removed from the distillation system as the bottoms product and, if necessary, it is subjected to an additional treatment for producing a gasoline component. The unreacted alkanol is removed as the overhead product of the distillation. According to the invention, the distillate withdrawn mainly contains an azeotrope of C3 hydrocarbons and alkanol, the C3 amount of which at least approximately corresponds to the C3 hydrocarbon concentration of the hydrocarbon feed, a substantial amount of the unreacted alkanol being removed in the form of said azeotrope. By means of the invention the need for a separate alkanol washing unit is eliminated in the apparatus which considerably reduces apparatus investment costs.

摘要： The invention concerns a process and an apparatus for preparing tertiary ethers. According to the process, C4 to C6 isoolefins and possibly heavier olefins contained in the feedstock are reacted with lower aliphatic alcohols, in particular methanol or ethanol, in a catalytic distillation reactor system in order to produce the corresponding ethers. According to the invention, the reaction between the isoolefins and the alcohols is essentially carried out in at least one reactor (5-7) of the kind, which is combined with a distillation column (3) intended for product separation, by conducting at least a part of the liquid flow of the column through the reactor and returning it to a lower tray than the one from which it was taken. At least half of cation exchange resin is placed in the side reactor (5-7). In the process according to the invention, the catalyst can be rapidly changed without stopping the process. In order to improve conversion additional alcohol can be fed to at least one of the side reactors.

摘要： The invention concerns a process for preparing a tertiary alkyl ether product. The process comprises reacting the isoolefins of an olefinic hydrocarbon feedstock in a reaction zone (1 - 3) with an alkanol to form a reaction mixture, which is subjected to distillation in a first distillation zone (4). The bottoms product of the first distillation contains the ether(s), whereas the overhead stream contains unreacted alkanol and a mixture of light hydrocarbons. The overhead stream is subjected to a second distillation in a second distillation zone (15). The overhead product of the second distillation mainly contains the lightest hydrocarbons and a small amount of alkanol, and the bottoms product contains an essentially oxygenate-free hydrocarbon stream which can be used as such for alkylation. In order to increase the conversion of the process, a side drawoff is withdrawn from the second distillation zone (15) and recirculated to the reaction zone (1 - 3).

摘要： A process for preparing tertiary alkyl ethers comprises the steps of reacting C4-7 isoolefins of an olefinic hydrocarbon feedstock with an alkanol in the presence of a first catalyst in a reaction zone to form a reaction mixture containing a tertiary alkyl ether or a mixture of tertiary alkyl ethers, feeding the reaction mixture to a distillation column, distilling the reaction mixture and recovering the alkyl ether(s) with the bottoms product of the distillation. An azeotrope formed by unreacted C4 hydrocarbons and the alkanol is withdrawn as an overhead product of the distillation. According to the invention, a part of the liquid flow of the column is withdrawn to form a side drawoff, and the side drawoff is recirculated to the reaction zone. As a result, the conversion of the reactive C6 hydrocarbons is increased and the operating cost of the ethers process is reduced.

摘要： the present invention concerns a process for producing 2-butyl-2-ethyl-1,3-propanediol. According to the process, a reaction mixture is formed, containing 2-ethylhexanal and formaldehyde, into which a hydroxide compound is fed, whereby 2-ethylhexanal and formaldehyde are reacted to produce 2-butyl-2-ethyl-1,3-propanediol. According to the invention, the hydroxide compound is incrementally fed into the reaction mixture. Preferably, the hydroxide compound is fed at least at two input rates, in such a way that the heat production of the reaction between 2-ethylhexanal and formaldehyde immediately after each increase of the input rate of the hydroxide compound is at least almost the same. The invention allows for the production of BEPD in a controlled and safe manner, with excellent yields.

摘要： In the preparation of alkenyl succinic anhydride (ASA) from an olefinically unsaturated hydrocarbon and a maleic anhydride, additives are used in the preparation reaction in order to improve the yield of the product and to reduce side reactions. According to the present invention, quinone and hydroquinone derivatives as well as dialkyl sulfoxides and transition-metal acetylacetonate have such properties. The amounts to be added are approx. 0.01-2 mol % of the amount of maleic anhydride. The olefin is preferably a straight-chain alpha -olefin or a straight-chain or branched internal olefin having a chain length of 6-20 carbon atoms. The olefin may also be a polyolefin, in which case the preferred molecular weight is 900-1500. The preparation process may be of the batch type or the semi-batch type, and the maleic anhydride and the additive may be added in several batches or as a continuous feed which may be even or variable. The ASA obtained by the process may be used in particular as an additive in foods, for hydroxy sizing of paper, or as a dispersing agent in lubricants.

摘要： The application relates to a process for the oligomerization of olefins, preferably a hydrocarbon blend which contains 1-butenes and/or 2-butenes, for example the so-called Raffinate II stream and cyclic aromatic or alicyclic hydrocarbons, by means of BF3 and a cocatalyst. The aromatic hydrocarbon may preferably be styrene, alpha-methyl styrene, alkyl styrene, or a blend thereof, and the alicyclic hydrocarbon may be vinyl cyclohexane, vinyl cyclohexene, or a blend thereof. The cocatalyst is an aliphatic alcohol, carboxylic acid or inorganic acid. The oligomerization may be carried out with or without a medium, at a temperature above 0 DEG C, by adjusting the pressure to 1-10 bar by means of BF3 gas. The oligomer prepared by the process may be used as a solvent or an additive in fuels or lubricants, in surfactants, in white and cosmetic oils requiring extra purity, and in PVC and polyolefin plastics. In polyester and vinyl ester resins this oligomer can be used for replacing in part the monomer (e.g. styrene), thus reducing monomer evaporation and to inhibit shrinkage at the hardening stage, and it also improves the optical properties of the said resins.
