    Abstract: Odor formation during storage of (hydrocarbylthio)aromatic amines due to formation and release of odoriferous sulfur-containing species such as dihydrocarbyldisulfides, is suppressed. To accomplish this, a small amount of N,N-dihydrocarbylhydroxylamine odor-inhibitor (e.g., N,N-diethylhydroxylamine) is blended with the (hydrocarbylthio)aromatic amine. This enables products such as a mixture of 3,5-di(methylthio)-2,4-diaminotoluene and 3,5-di(methylthio)-2,6-diaminotoluene) to be stored for long periods of time with significantly reduced formation and release of odoriferous sulfur-containing species.

    Abstract translation: 抑制由于含有臭味的含硫物质如二烃基二硫化物的形成和释放而在（烃硫基）芳族胺储存期间的气味形成。 为了实现这一点，将少量的N，N-二烃基羟胺气味抑制剂（例如N，N-二乙基羟胺）与（烃硫基）芳族胺共混。 这使得诸如3,5-二（甲硫基）-2,4-二氨基甲苯和3,5-二（甲硫基）-2,6-二氨基甲苯的混合物的产物能够长时间储存​​，同时显着减少了形成 并释放有气味的含硫物质。
