  • Method and Device for the Sulfonation or Sulfation of Sulfonatable or Sulfatable Organic Substances and for Performing Faster, Strongly Exothermic Gas/Liquid Reactions
    申请人:Aigner Rudolf

    A method and a device for the sulfonation or the sulfation of organic liquid raw materials with an S0 3 /air mixture and other reaction gases in order to perform rapid, highly exothermic gas-liquid reactions in conventional thin-layer falling-film reactors are disclosed. The introduction of the S0 3 /air mixture occurs through several feed locations, which are located within (along) the reaction tube or reaction tubes or in the annular gap of annular-gap falling-film reactors. High peak temperatures, undesirable byproducts, worsening of the color and local oversulfation or oversulfonation, which leads to side reactions, are largely avoided.
    本发明揭示了一种用S03/空气混合物和其他反应气体对有机液体原料进行磺化或硫酸化的方法和装置,以便在传统的薄层下降膜反应器中进行快速、高放热气液反应。S03/空气混合物的引入通过位于反应管或反应管内或环形间隙内的几个进料位置进行。大部分避免了高峰温度、不良副产品、颜色恶化和局部过磺化或过硫酸化,从而导致副反应。

  • Benzoyl Peroxide Composition, Methods for Making Same, and Pharmaceutical or Cosmetic Formulations Comprising Same, and Uses Thereof
    申请人:Levin Daniel
    公开号:US20120064135A1
    公开(公告)日:2012-03-15
    The present invention relates to the preparation of compositions comprising benzoyl peroxide, with or without other additional active ingredients. The process involves introducing benzoyl peroxide, along with any other active ingredients present, into a fatty substance that contains and protects the ingredients that would otherwise be unstable when in contact with one another. The composition is designed to allow all ingredients to become available for skin contact or skin absorption when the fatty substance softens and/or melts as the composition is applied to the skin. The benzoyl peroxide may be pre-micronized to a particle distribution size of about d 90 of 0.1 to 150 microns, preferably d 90 of 10 to 15 microns. Further, pharmaceutical or cosmetic ingredients may be contained within the fatty substances, with or without, benzoyl peroxide therein or may be present outside of the fatty substance but elsewhere within formulated pharmaceutical or cosmetic products using the active ingredients protected by the fatty substance. These compositions are useful in aqueous-based formulations to treat diseases by topical, transdermal and/or subcutaneous administration.
    本发明涉及制备包含过氧苯甲酰的组合物,可包含其他额外活性成分。该过程涉及将过氧苯甲酰以及其他任何活性成分引入含有并保护这些成分的脂肪物质中,以防止它们在接触时变得不稳定。该组合物设计为在脂肪物质软化和/或融化时,使所有成分可用于皮肤接触或皮肤吸收。过氧苯甲酰可以经预微粒化处理,粒度分布大小约为d90的0.1至150微米,优选d90的10至15微米。此外,医药或化妆品成分可以包含在脂肪物质中,其中可能含有或不含有过氧苯甲酰,或者可能存在于脂肪物质之外,但在使用脂肪物质保护的活性成分的制剂医药或化妆品产品中的其他地方。这些组合物可用于治疗疾病的水基配方,通过局部、经皮和/或皮下给药。
