comprising a major proportion of an oil of lubricating viscosity and a minor amount of a silver protective agent comprising the reaction product of a C 5 to C 60 carboxylic acid and at least one amine selected from the group consisting of (1) guanidine, urea, and thioruea compounds; (2)...
载玻片表面修饰羧基(carboxylic acid);羧基修饰生物芯片 羧酸盐(Carboxylate)官能基团载玻片 该载玻片在PH大于4的缓冲液中带负电荷。在使用EDC/NHS活化后,他们可以与具有伯胺基团(primary amine groups)的生物分子共价结合。这种结合比醛-胺结合(aldehide-amine binging)更* 。聚乙二醇(PEG)是可抵抗非* 性吸附的单...
1 Workflow for enumeration of amine–acid transformations. For a pair of coupling partners, we consider a reaction at the functional group A (amine) and B (carboxylic acid oxygen, B[O] or carbon, B[C]). Deamination reactions are noted as −A and decarboxylation reactions are noted as ...
The α-ω epoxyesters presented serve as a means to introduce carboxylic acid and amine functional groups into poly(lactic acid) polymers via ring-opening copolymerization. 展开 关键词: poly(lactic acid copolymerization α,ω-epoxyesters carboxylic acid amine ...

BDP R6G hydrazide荧光染料,BDP 630/650 carboxylic acid/amine/tetrazine BDP R6G hydrazide BDP R6G是一种硼二吡咯烯染料,其吸收和发射光谱类似于R6G(罗丹明6G)。这种酰肼是一种羰基反应性化合物,用于标记醛、酮和大多数碳水化合物(用高碘酸盐氧化)。
The reaction with aldehyde is the one of most concern: RCOH+12O2=RCOOH Since catalysts may promote the oxidation of aldehydes, the presence of carboxylic acid may be a concern for exhaust components downstream of a catalyst. View chapterExplore book Carboxylic Acids Robert J. Ouellette, J. ...
