  Provided are an aromatic polycarbonate copolymer and a method for producing it. An aromatic dihydroxy compound, at least one member selected from the group consisting of polyorganosiloxanes and aliphatic polyalcohols, and a dicarbonate are prepolymerized under heat to give a polycarbonate prepolymer, and the prepolymer is polymerized in a solid or swollen solid phase in the presence of a quaternary phosphonium salt serving as a catalyst to give an aromatic polycarbonate copolymer. The remaining monomer content, the acetone soluble content (that is, the low-molecular-weight substance content) and the cyclic oligomer content of the copolymer are all reduced, and the terminal hydroxyl fraction thereof is also reduced.

  本发明提供了一种芳香族聚碳酸酯共聚物及其生产方法。一种芳香族二羟基化合物、至少一种选自聚有机硅氧烷和脂肪族多元醇组成的组的成员和一种二碳酸盐在加热下预聚，得到一种聚碳酸酯预聚物，该预聚物在作为催化剂的季鏻盐存在下在固相或膨胀固相中聚合，得到一种芳香族聚碳酸酯共聚物。共聚物的剩余单体含量、丙酮可溶物含量（即低分子量物质含量）和环状低聚物含量都会降低，其末端羟基部分也会降低。

  Disclosed are polycarbonates which are obtained by preparing a polycarbonate prepolymer through prepolymerization followed by polymerizing it through solid-phase, swollen solid-phase or thin film melt-phase transesterification, and have a remaining monomer content of smaller than 100 ppm, especially a dihydroxy compound content of smaller than 100 ppm, or have an acetone soluble content of at most 3.5 or at most 3.0 % by weight, or have a terminal hydroxyl fraction of smaller than 2 or smaller than 15 mol%; and optical materials and blow molding materials comprising the polycarbonate. The polycarbonates contain a reduced amount of impurities such as remaining monomers, oligomers and others and have improved physical properties including impact strength, and these are useful as optical materials and blow molding materials.

  所公开的聚碳酸酯是通过预聚合制备聚碳酸酯预聚物，然后通过固相、膨胀固相或薄膜熔融相酯化聚合而得，其剩余单体含量小于 100 ppm，特别是二羟基化合物含量小于 100 ppm，或丙酮可溶物含量最多为 3.5 或最多 3.0%（按重量计），或末端羟基部分小于 2 或小于 15 摩尔%；以及包含这种聚碳酸酯的光学材料和吹塑材料。这种聚碳酸酯含有较少的杂质，如剩余的单体、低聚物和其他物质，具有更好的物理性能，包括冲击强度，可用作光学材料和吹塑材料。
• Mixing-assisted oxidative desulfurziation method of diesel fuel and device thereof

  Mixing-assisted oxidative desulfurization method of diesel fuel and the continuous desulfurization device thereof is disclosed herein. Because of the dangers of sulfur content in gasoline and other petroleum products, many governments have required the sulfur content of these petroleum products to be reduced so as to safeguard public safety and health. Desulfurization of fossil fuels is provided by the combination of fossil fuels with an aqueous mixture of ozone or hydrogen peroxide and a Tetraoctylphosphonium salt phase transfer catalyst, and the mixture is then reactive mixed to form oxidize sulfur compounds in the fuel. The polar oxidized sulfones species are removed via another mixing step. The desulfurization device (10) can be in the form of a portable device which provides for continuous mixing-assisted desulfurization for the selective removal of sulfur containing compounds from fossil fuels such as diesel fuel or other hydrocarbons.

  本文公开了柴油的混合辅助氧化脱硫方法及其连续脱硫装置。由于汽油和其他石油产品中硫含量的危害，许多国家的政府都要求降低这些石油产品的硫含量，以保障公众的安全和健康。化石燃料的脱硫方法是将化石燃料与臭氧或过氧化氢的水性混合物以及四辛基膦盐相转移催化剂结合，然后将混合物进行反应混合，形成燃料中的氧化硫化合物。极性氧化砜类物质通过另一个混合步骤去除。脱硫装置（10）可以是一种便携式装置，用于连续混合辅助脱硫，选择性地去除化石燃料（如柴油或其他碳氢化合物）中的含硫化合物。
