    • A surface-modified adsorbent comprises a reagent on a porous carrier. Preferred porous carriers are adsorbent carbons such as activated carbon, silica gels, aluminas, polyester resins, zeolites or zeolite-like materials, and mixtures thereof. An exemplary porous carrier is activated carbon comprising at least about 80% micropores and having an average particle size from about 6 mesh to about 300 mesh or an average particle size from about 0.2 mm to about 1 mm. The reagent preferably comprises 1 to 80% or 3 to 10% by weight of the adsorbent. Preferred reagents are 2-hydroxymethylpiperidine (2-HMP) or a 2-HMP analogues such as 2-(2-piperidine)ethanol (2-PE), N-piperidineethanol (N-PE), 2-(4-piperidine)ethanol (4-PE), 3-hydroxypiperidine hydrochloride (3-HPH), 4-hydroxypiperidine (4-HP), 3-N-piperidinyl-1,2-propanediol (3-PDP), 2-amino-1-phenylethanol (2-APE), 2-(N-anilino)ethanol (2-AE), and S-(−)2-phenylglycinol (2-PG). Surface modified adsorbents can be incorporated into cigarettes, preferably in an amount effective to reduce the concentration of one or more constituents of cigarette smoke.
    • 表面改性吸附剂包括在多孔载体上的试剂。 优选的多孔载体是吸附剂碳,例如活性炭,硅胶,氧化铝,聚酯树脂,沸石或类沸石材料,以及它们的混合物。 示例性多孔载体是包含至少约80%微孔并且具有约6目至约300目的平均粒度或约0.2mm至约1mm的平均粒度的活性炭。 试剂优选占吸附剂重量的1〜80%或3〜10%。 优选的试剂是2-羟甲基哌啶(2-HMP)或2-HMP类似物如2-(2-哌啶)乙醇(2-PE),N-哌啶乙醇(N-PE),2-(4-哌啶)乙醇 (4-PE),3-羟基哌啶盐酸盐(3-HPH),4-羟基哌啶(4-HP),3-N-哌啶基-1,2-丙二醇(3-PDP),2-氨基-1-苯基乙醇 2-APE),2-(N-苯胺基)乙醇(2-AE)和S - ( - )2-苯基甘氨醇(2-PG)。 表面改性吸附剂可以并入香烟中,优选以有效降低香烟烟雾的一种或多种成分浓度的量。
