摘要： Procedure for manufacturing a tube of insulating material comprising one or several inner tubes (17), a foamed plastic insulation (18) and a plastic surface layer (16). In the procedure, foaming material is conducted to encircle the inner tube (17), and similarly plastic raw material to form the surface layer (16), and around the inner tube (17) are formed the foamed plastic insulation (18) and the surface layer (16) simultaneously in one work step. The surface layer (16) is cooled to desired dimension in a calibration means (14) in which a calibration pressure is produced by the foaming process, the release of this pressure being prevented by the plug which the foam forms as it solidifies. Control of the calibration pressure is effected by regulating the foam raw material supply and the temperature of the raw material.

摘要： The invention relates to a process for preparing monoesters of 1,3-diols. The invention relates to a process for preparing in particular 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, according to which process isobutyraldehyde is brought into contact with an alkalihydroxide catalyst. The alkali hydroxide catalyst used according to the invention is a dilute solution of lithium hydroxide, in which the concentration of lithium hydroxide is about 1 - 12 % by weight. An aqueous solution containing about 2 - 10 % by weight of sodium hydroxide and about 0.1 - 6 % by weight of lithium hydroxide, is used preferably. This enhances selectivity with respect to 1,3-diols, with an increased conversion of the aldehyde into a monoester and a subsequent decrease in recirculation volumes in the preparation process.

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： 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： 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 application relates to a process for the oligomerization of aromatic or alicyclic hydrocarbons by means of a complex made up of BF3 and a cocatalyst. The aromatic hydrocarbon may preferably be styrene, alpha-methyl styrene, or a mixture thereof, and the alicyclic hydrocarbon may be vinyl cyclohexane, vinyl cyclohexene, allyl cyclohexane, allyl cyclohexene, or a mixture thereof. The cocatalyst is an aliphatic alcohol, carboxylic acid, or inorganic acid. The oligomerization may be performed with or without a medium, at a temperature above 0 DEG C, the pressure being adjusted by means of BF3 to 1 - 10 bar. An oligomer prepared by the process can be used as a solvent or an additive in fuels or lubricants, in surfactants, in white oils and cosmetic oils requiring extra purity, and in PVC and polyolefin plastics. In polyester and vinyl ester resins this oligomer can be used to replace in part a monomer (e.g. styrene), thus reducing the evaporation of monomer, and to inhibit shrinkage at the hardening stage, and it also improves the optical properties of the said resins.

The depth of grooves (11) in the surface of thermal insulation board (10) is chosen so that when embedded against bottom (12) of groove (11), the vertical load-bearing stud (20) will protrude from the surface level of thermal insulation board (10) by a distance equal to the thickness of additional insulation layer (40). The vertical sides of thermal insulation board (10) have grooves (14) and corresponding protrusions (15) to join the thermal insulation boards (10) of adjacent elements with a tongue-and-groove joint.
