Silica gel-supported SMAPs, [silicagel 60N]-SMAP (4A) and [CARiACT Q-10]-SMAP(4B), consisting of a compact trialkylphosphine(SMAP) were prepared. Thus, the reaction of Ph-SMAP (1) with TfOH afforded silyl triflate 2. Sur-face treatment of silica gel 60N and CARiACTQ-10 with 2 ...
多层硅胶柱 Presep(R) Multilayer Silica Gel 使用HPLC进行二噁英分析中,需要使用由多种化学物质改性的硅胶组成的多层硅胶柱进行预处理,用以除去样本中存在的含硫化合物、多环芳烃和有色物质等。制备这种多层硅胶预处理柱非常繁琐, Presep(R) Multilayer Silica Gel解决了这一问题。该产品是与JIS二恶英类分析相关规定...
Solid-supported phosphine ligands silica-SMAPs {[silica gel 60N]-SMAP (1a) or [CARiACT Q-10]-SMAP (1b)}, which are composed of a caged, compact trialkylphosphine (SMAP) as a ligand and silica gel (silica get 60N or CARiACT Q-10) as a support,'were synthesized through surface ...
Analytical thin layer chromatography (TLC) was performed on a silica gel plate (Merck, Silica gel 60 F254, 20 × 20 cm, 0.25 mm). Column chromatography was carried out with silica gel [Silica gel 60 (63–210 m, Merck), or Silica gel 60N (63–210 m, Kanto Chemical)] as ...
The pure silica WMS was synthesized via a sol-gel procedure using DDA as an organic template and TEOS as the silica source, with a gel molar composition of 0.05 TEOS: 0.02 DDA: 2.94 H2O: 0.74 THF. Typically, 3.75 g of DDA was dissolved in 53.05 g of deionized water and 13.34 g of ...
