What do the CA and PCA values represent?
Thread Content
The refined furfural extract oil has analysis parameters for CA and PCA values; what do these values mean? Thank you!
CA – condensed aromatics, polycyclic aromatic compounds; PCA – polycyclic aromatic compounds, also known as PAHs
Do polycyclic aromatic hydrocarbons also include fused ring aromatic hydrocarbons?
Aromatic hydrocarbons CA Polycyclic aromatic compounds PCA
Reply to 3# abdulla: Polycyclic aromatic hydrocarbons can be classified into three categories structurally: one category consists of polycyclic aromatic hydrocarbons in which benzene rings are directly connected to other aromatic rings； Another category consists of polyaromatic alkanes formed by multiple benzene rings or other aromatic compounds being connected together through a carbon atom or carbon chain ； The third category consists of linear or nonlinear polyaromatic compounds formed by connecting every two benzene rings through two shared carbon atoms; these are commonly known as fused aromatic compounds or polycyclic aromatic compounds. Heterocyclic aromatics are polycyclic aromatics formed by the fusion of two or more benzene rings sharing two adjacent carbon atoms.
It shares a property with the Na.pna we analyzed: the former has a single property, while the latter has a complex composition
Are polycyclic aromatic hydrocarbons (PCAs) and polycyclic aromatic hydrocarbons (PAHs) the same thing? But what we often measure is PCA! Hehe
