Carbonyl compounds with the structure (1) Formula (1) in which the radical R1 is hydrogen or an alkyl group, with 1 to 5 carbon atoms, the radicals R2 and R3 are independently from each other hydrogen or an alkyl group with 1 at 3 carbon atoms and a double bond C-1 / C-2, C-...
of carbon compounds. Coke and charcoal are nearly pure carbon.) In addition to its uses in making inks andpaints, carbon black is added to the rubber used in tires to improve its wearing qualities.Bone black, or animal charcoal, can adsorb gases and colouring matter from many other ...

Carbon monoxide’stoxicityis a consequence of its absorption byred blood cellsin preference tooxygen, thus interfering with the transport of oxygen from thelungsto the tissues, in which it is required. Indication ofcarbon monoxide poisoningincludeheadache, weakness, dizziness,nausea,fainting, and, in...

The molecular composition of soil organic carbon remains contentious. Microbial-, plant- and fire-derived compounds may each contribute, but whether they vary predictably among ecosystems remains unclear. Here we present carbon functional groups and mole
aInternational competition for talent is fierce, the developed countries can take lots of measures such as expanding the talent migration, increasing research investment, providing high returns, improving the education and training conditions to attract and retain students for its large num 国际竞争为天...
The reaction of lithium dialkylamides 1 (dialkyl = dibutyl, dipentyl, dicyclohexyl, 3-oxapentamethylene, and isopropyl cyclohexyl) with carbon monoxide was examined under several reaction conditions. It is shown that the corresponding lithium carbamoyl is the first intermediate and its further reactions...
