    • A composition for reducing undesirable odors emitted by hydrocarbonaceous materials is provided. The composition contains at least one aldehyde-containing compound and, optionally, one or more ketone-containing compound and/or a carrier. The composition is free of ester-containing compounds. In at least one exemplary embodiment, the composition contains one or more aldehyde-containing compounds and a liquid carrier. The aldehyde-containing compound(s) has a molecular weight greater than 100 daltons and may be chosen from vanillin or cinnamaldehyde. The ketone-containing compound(s) has a molecular weight greater than 100 daltons, and in exemplary embodiments, from about 120 to about 1,000 daltons. Undesirable odors from hot asphalt are reduced by the composition without adversely affecting the physical and performance properties of the asphalt or decreasing the flash point of the asphalt. The composition may be added to asphalt in a molten or semi-molten form to reduce or eliminate unpleasant odors and form a low odor asphalt.
    • 提供了一种用于减少烃类材料排放的不良气味的组合物。 组合物含有至少一种含醛化合物和任选的一种或多种含酮化合物和/或载体。 该组合物不含含酯化合物。 在至少一个示例性实施方案中,组合物含有一种或多种含醛化合物和液体载体。 含醛化合物的分子量大于100道尔顿,可以选自香草醛或肉桂醛。 含酮化合物的分子量大于100道尔顿,在示例性实施方案中为约120至约1,000道尔顿。 来自热沥青的不良气味被组合物减少,而不会不利地影响沥青的物理性能和性能,或降低沥青的闪点。 可以将组合物以熔融或半熔融形式加入到沥青中以减少或消除不愉快的气味并形成低气味沥青。
