What is tert in organic chemistry? What is isomerism in organic chemistry? Is water a polymer? What is HX in organic chemistry? What is metamerism in organic chemistry? What is fugacity in physical chemistry? What is general organic chemistry? What does THF do in organic chemistry? What is...
The adjacent bis-THF subunit was constructed by a multiple Williamson reaction. The left and the right side chain were added by addition of organomagnesium compounds to aldehyde functions. The conversion of a carboxylic acid into the butenolide moiety concluded both syntheses. Zhou et al. reported...
NBS is a chemical reagent used in organic chemistry in electrophilic addition reactions and radical substitution. In bromination of olefins; in oxidation of alcohols to aldehydes and ketones and of aldehydes to acid bromides. N-Bromosuccinimide (NBS) in combination with LiBr can also be used in ...
The comparison of adsorption affinities on various ACFs showed that the order in sensitivity to carbon surface chemistry is PFOA ≫ octanoic acid > phenanthrene. On the other hand, Kd and qm for PFOA adsorption strongly correlate with the anion exchange capacity of various AC materials. Thus, ...
A good meal cannot be defined in an absolute manner since it depends strongly on where and how it is eaten and how many people participate. A picnic shared by hikers after a challenging climbing is very different from a birthday party among a family or a
