The invention provides a method of isolating certain target compounds from tobacco, tobacco materials or smoke generated by a smoking article. The method can be used to remove undesirable compounds from tobacco, tobacco materials, or tobacco smoke. The method can also be used to remove flavor compounds from tobacco or tobacco materials, which can then be used as flavor components for tobacco material used in smoking articles and smokeless tobacco compositions.

Disclosed herein are salicylic acid copolymers having a weight average molecular weight of 500 10,000 and obtained (a) by condensing salicylic acid (i) with a benzyl alcohol (ii) and/or benzyl ether (iii) or a benzyl halide (iv) in the presence of an acid catalyst or (b) by reacting a co-condensation resin of (i) and (ii) and/or (iii) with (iv) or (c) by reacting a co-condensation resin of (i) and (ii) and/or (iii) or (iv) with a styrene derivative in the presence of an acid catalyst; multivalent metal salts of the salicylic acid copolymers; color-developing agents comprising the multivalent metal salts; and color-developing sheets suited for pressure-sensitive copying paper and comprising the color-developing agents. Their production processes are also disclosed.
A color-developing composition comprises a multivalent-metal-modified salicylic acid resin (Resin A) and a polycondensation resin (resin B) at a weight ratio of 90-30 to 10-70. Resin A is composed of 5-35 mole% of a structural unit (I) and 65-95 mole% of at least one structural unit (II) or 65-95 mole% of a coupled structural unit of at least one unit (II) and at least one unit (III) and has a weight-average molecular weight of 350-5,000. Resin B is composed of the unit (II) and/or the unit (III) and has a weight-average molecular weight of 350-5,000.
wherein Z represents M/m, M being a metal ion of m valence and m being an integer; R₁ and R₂ represent H or a C₁₋₁₂ alkyl, aralkyl, aryl or cycloalkyl group; R₃ and R₆ represent H or a C₁₋₄ alkyl group; and R₄ and R₅ represent H or CH₃.
一种显色组合物包括一种多价金属改性水杨酸树脂(树脂 A)和一种缩聚树脂(树脂 B),两者的重量比为 90-30 比 10-70。树脂 A 由 5-35 摩尔%的结构单元(I)和 65-95 摩尔%的至少一个结构单元(II)或 65-95 摩尔%的至少一个单元(II)和至少一个单元(III)的耦合结构单元组成,其重量平均分子量为 350-5000。树脂 B 由单元(II)和/或单元(III)组成,重量平均分子量为 350-5000。
其中 Z 代表 M/m,M 为 m 价金属离子,m 为整数;R₁ 和 R₂ 代表 H 或 C₁₋₁₂ 烷基、芳基、芳烷基或环烷基;R₃ 和 R₆ 代表 H 或 C₁₋₄ 烷基;以及 R₄ 和 R₅ 代表 H 或 CH₃。
