    摘要: A method of making a low-fluoride reactive PIB composition includes (a) providing a modified C4 feedstock by way of blending a mixed C4 feedstock with a second feedstock having a lower LB/IsoB ratio; or providing a C4 feedstock with an LB/IsoB index of less than 10%; (b) feeding the modified C4 feedstock or the C4 feedstock with an LB/IsoB index of less than 10% to a CSTR with a homogeneous catalyst comprising BF3 and a modifier selected from alcohols, ethers and mixtures thereof; (c) polymerizing the modified C4 feedstock or the C4 feedstock with an LB/IsoB index of less than 10% in the reactor while maintaining the reactor at a temperature above −15° C. and utilizing a residence time less than 45 minutes to produce a crude PIB composition in a polymerization mixture; and (d) recovering a purified PIB composition from the polymerization mixture having a molecular weight, Mn, from 250 to 5000 Daltons and an alpha vinylidene content of at least 50 mol %. The crude PIB composition suitably has a fluoride content of less than 100 ppm and the purified PIB composition has a fluoride content of less than 20 ppm in preferred embodiments. In the most preferred embodiments, ammonium salts are used to neutralize the catalyst and fluoride salts are sublimed from the product at elevated temperatures.

    摘要: Embodiments of an injection device shaped in order to atomize a liquid into droplets by means of a gas are disclosed herein. The injection device may comprise a body having a gas inlet orifice intended to be connected to a gas supply duct. The injection device may further comprise an outlet orifice for discharging the atomized liquid. The injection device may also comprise a straight internal duct connecting the inlet orifice to the outlet orifice along an axial direction of said body. At least two liquid inlet ducts may be intended to be connected to at least one liquid supply duct pass through said body radially or substantially radially and open into said internal duct. These liquid inlet ducts may each have an axis and are arranged so that their axes intersect at one and the same point on an axial line extending inside the internal duct.

    摘要: A continuous polymerization apparatus uses at least a first reactor and a second reactor (10, 20). Each of the reactors (10, 20) comprises a supply port (11a, 21a) and an effluent port (11b, 21b). The supply port (11a) of the first reactor (10) is connected to supply sources (1, 3) of a raw material monomer and a polymerization initiator, and the effluent port (11b) thereof is connected to the supply port (21a) of the second reactor (20) by a connection line (15a). The connection line (15a) is combined with a replenishing line (15b) through an injection valve (50) at a combining part. The injection valve (50) comprises, in a full closure state thereof, a clearance that may cause a fluid comprising at least the raw material monomer to flow from the replenishing line (15b) to the connection line (15a).

    摘要: The invention relates to a device for synthesizing a polymer accompanied by separating a gaseous substance. Said device comprises: a reactor chamber (1) having a substantially circular cylinder-shaped upper section (11), which is delimited by two circular surfaces (111, 112) and a circumferential surface (113) and has a longitudinal cylinder axis, and a lower section (12), the upper section (11) and the lower section (12) being connected to one another via the first circular surface (111); an inlet opening (2); a first outlet opening (3), which is arranged in a wall of the lower section (12); a second outlet opening (4), which is arranged in the second circular surface (112) or in the circumferential surface (113) between the inlet opening (2) and the second circular surface (112); and a removal device (51), which is arranged so as to be movable along the longitudinal cylinder axis at least between the second circular surface (112) and the inlet opening (2), and contacts the circumferential surface (113). The invention further relates to a method comprising: feeding an oligomer melt (7) into a circular cylinder-shaped first section (11) of a reaction chamber (1) through an inlet opening (2) tangentially to a circumferential surface (113) of the first section (11); polymerizing the oligomer melt (7) to form a polymer melt (8); removing the polymer melt (8) from the reaction chamber (1) through a first outlet opening (3) of the reaction chamber (1); and removing a gaseous substance (9) from the reaction chamber (1) through a second outlet opening (4) of the reaction chamber (1) above the inlet opening (2). Deposits on at least one inner wall of the first section (11) of the reaction chamber (1) above the inlet opening (2) are removed by a removal device (51).
