Functional groups can be attached to basic groups of carbon atoms by replacing the H atom. For instance, polypropylene has the same basic structure as polyethylene but the “H” atom is replaced with a methyl group,“CH3,” as shown in Fig. 2.3. Sign in to download full-size image Fig....

Chemical transformations that introduce, remove or manipulate functional groups are ubiquitous in synthetic chemistry1. Unlike conventional functional-group interconversion reactions that swap one functionality for another, transformations that alter sol

A functional polymer having active and stable functional groups, for separation or reactive processes in chemical manufacture or analysis, has carbon-linked functional groups on dimethylene spacers; a method of preparation is from pre-existing polymers comprising polymeric 1-(vinylphenyl)ethylene repeat...
Our findings support the hypothesis that the succession of bacterial taxonomic groups occurring in SOM- and FOM-degrading communities during the degradation process may be an important driver of the PE, and consequently of carbon dynamics in soil. 展开 ...
Process for introducing a substituent selected from branched- or straight-chain alkyl radicals having from 1 to 12 carbon atoms, aralkyl or cycloalkyl radicals in which the alkyl moiety has from 1 to 4 carbon atoms, into a carbon chain bearing a stable functional group the said carbon chain ...
Ether and amide chemical groups are present in many pharmaceutically active agents. This new method provides an environmentally friendly way for pharmaceutical companies to produce pharmaceutical products involving the modification of these chemical groups. ...
