Popov, V. A.; Baboshin, Yu. V.; Belavina, I. G.; Cherkasov, N. Kh. published an article about the compound: quinoliniumhydrogensulphate( cas:530-66-5,SMILESS:[O-]S(=O)(O)=O.C12=CC=C[NH+]=C1C=CC=C2 ).Safety of quinoliniumhydrogensulphate. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:530-66-5) through the article.
The extraction of heterocyclic nitrogenous bases from absorption oil fractions containing ∼9% bases, 10% naphthalene, and up to 10% phenols with 30% H2SO4 [7664-93-9] or 30% H3PO4 [7664-38-2] is described. H2SO4 has a higher extraction efficiency than H3PO4, but H3PO4 is less corrosive and has less tendency to gum formation. The removal of phenols during H2SO4 treatment is not so complete and this may double the amount of unextracted bases. The presence of phenols also increases the acid consumption. The solubility of the acid sulfate and monophosphate in the absorption oil fraction is ∼0.15% by volume at 20°. This value agrees with the residual after treatment with 80% excess H2SO4. Treatment with H3PO4 under similar conditions leads to a 10-fold increase in the residual unextracted bases.
When you point to this article, it is believed that you are also very interested in this compound(530-66-5)Safety of quinoliniumhydrogensulphate and due to space limitations, I can only present the most important information.
