  A non-aqueous absorbent comprising a crosslinked polymer which contains a structural unit having a carboxyl group and/or a sulfonate group in an amount of 20 to 100% weight in its molecule and in which from 30 to 100% by mol of the protons in the carboxyl group and/or the sulfonate group have been substituted by onium cations; a non-aqueous gel made of this non-aqueous absorbent and an organic solvent; and a non-aqueous absorbent sheet and a non-aqueous absorbent agent containing the non-aqueous absorbent. Because of having excellent capabilities of absorbing and holding various organic solvents such as alcohols and gelating, these materials are usable for various purposes, for example, lithium batteries, alcohol-based bactericidal materials or alcohol-based bactericides, cold insulating materials or cold insulators, gel sheets for cooling, fuel compositions for solid fuels or solid fuels using the same, fragrance materials or fragrances, patch materials or patches, insecticidal compositions or insecticides, fuel stores for fuel batteries or fuel batteries using the same.

  一种非水吸收剂，包含交联聚合物，其分子中含有具有羧基和/或磺酸基的结构单元，其含量为20至100％重量，并且其中羧基和/或磺酸基中的30至100％摩尔的质子已被离子上离子替代物取代；由此制成的非水凝胶和有机溶剂；以及含有非水吸收剂的非水吸收剂片和非水吸收剂剂。由于具有吸收和保持各种有机溶剂（如醇类）的能力，以及凝胶化，这些材料可用于各种用途，例如锂电池，醇基杀菌材料或醇基杀菌剂，冷绝缘材料或冷绝缘材料，用于冷却的凝胶片，用于固体燃料的燃料组合物或使用相同的固体燃料，香料材料或香料，贴片材料或贴片，杀虫组合物或杀虫剂，燃料电池的燃料存储器或使用相同的燃料电池。

  The invention provides the use of enzymes derived from plants in biocatalysis. The regio- and stercoselective introduction of an oxygen group into an unactivated organic compound is still a largely unresolved challenge to organic chemistry (Faber, 2000). We have shown that enzymes of Asteraceae species are capable of converting with high regio- and stereospecificity for example sesquiterpene olefins to commercially interesting products.

  本发明提供了植物来源酶在生物催化中的应用。将氧基引入未活化有机化合物中的区域和立体选择性仍然是有机化学中一个基本未解决的挑战（Faber，2000）。我们已经证明，菊科物种的酶能够高度区域和立体特异性地将倍半萜烯烃等转化为商业上有趣的产物。
