The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: quinoliniumhydrogensulphate(SMILESS: [O-]S(=O)(O)=O.C12=CC=C[NH+]=C1C=CC=C2,cas:530-66-5) is researched.Recommanded Product: 580-34-7. The article 《The structural systematics of protonation of some important nitrogen-base ligands. III. Some (univalent) anion salts of some hindered unidentate nitrogen bases》 in relation to this compound, is published in Zeitschrift fuer Anorganische und Allgemeine Chemie. Let’s take a look at the latest research on this compound (cas:530-66-5).

Recent structural studies of salts of the 2,2,6,6-tetramethylpiperidinium cation [tmpH]+ (chloride, bromide; thiocyanate) present as interesting dimeric or polymeric associations linked by pairs of directional H-bonds from the cationic = NH+2 moieties to ‘two-coordinate’ anions. Present single crystal x-ray studies have characterized the iodide, perchlorate, nitrate and trifluoroacetate complexes, all, like those of the preceding studies, [tmpH]+X- (anhydrous). A variety of forms are found: the nitrate compound is dimeric [[tmpH](O·NO·O)2[Htmp]], the trifluoroacetate compound being similar in form while the iodide and perchlorate salts are mixtures of dimers (with the anions essentially single atom bridges) and single-stranded helical polymers, the stoichiometric ratio of these being 1:1 and 2:1 in terms of [tmpH]X formula units, resp. A study of 4-keto-2,2,6,6-tetramethylpiperidinium thiocyanate shows it to be a dimer [[OtmpH](SCNNSC)[HtmpO]], unlike its previously studied chloride analog which is a cyclic tetramer. A new P21/n phase of diisopropylammonium chloride, derivative of the previously described P212121 and P21 forms, is reported, together with descriptions of protonated salts of the other hindered unidentate bases 2,6-lutidine (as the chloride salt), quinoline (as the perchlorate, trifluoroacetate, hexachlorostannate and bisulfate salts) and 2-quinaldine (as the chloride (anhydrous and monohydrate) and hexachlorostannate salts), all displaying arrays derivative of ion-pair formation (extended by anion-anion H-bonds as well in the bisulfate salt) and, in the case of the aromatic bases, dominated by parallel stacking.

From this literature《The structural systematics of protonation of some important nitrogen-base ligands. III. Some (univalent) anion salts of some hindered unidentate nitrogen bases》,we know some information about this compound(530-66-5)COA of Formula: C9H9NO4S, but this is not all information, there are many literatures related to this compound(530-66-5).

We’ll tell you more about this compound (cas:530-66-5).

Crystal engineering was invoked to design structural analogs of 2 prototypic SHG active solids, p-nitroaniline (pNA) and K dihydrogen phosphate (KDP). PNA exists as linear polar strands because of head-to-tail H bonding between adjacent mols. whereas KDP is a self-assembled H bonded diamond-type network that becomes polar when the H bonds align. The authors detail preparation and crystallog. characterization of 2 classes of multicomponent solid, organic cation H sulfates and co-crystals of the cubane cluster [M(CO)3(μ3-OH)]4, which structurally mimic pNA and KDP, resp.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis, characterization and photochromic properties of novel spirooxazines, published in 2013-05-31, which mentions a compound: 530-66-5, mainly applied to spiro indoline naphthoxazine preparation photochromism merocyanine, SDS of cas: 530-66-5.

A series of spirooxazine compounds were synthesized via condensation reaction of 1,3,3-trimethyl-2-methyleneindoline with 1-nitroso-2,7-naphthalenediols, followed by esterification with acyl chlorides. Absorption bands in the visible region were observed in UV spectra (λmax: 530-665 nm), which were red-shifted as the polarity of solvent increased. Furthermore, these absorption bands also red-shifted with the increase of the electron-donating ability of the 6′-heterocycle substituent, but were nearly unaffected by 9′-acyloxy. Thermal decoloration showed that the thermal relaxation progress of the photomerocyanine followed 1st order kinetics and the relaxation time was tuned in a broad range from 125-1886 s (at 20°) by changing electron-donating power on 6′-heterocycle and 9′-acyloxy.

The article 《Separation of quinaldine from a ternary mixture with quinoline and isoquinoline》 in relation to this compound, is published in Zhurnal Prikladnoi Khimii (Sankt-Peterburg, Russian Federation). Let’s take a look at the latest research on this compound (cas:530-66-5).

The solubility relations of the monophosphate and bisulfate salts of quinaldine (I), quinoline (II), and isoquinoline (III) were studied. The solubility of the monophosphate of III in H2O at 25° is 6.7 times that of I or II. The solubility of the bisulfates of I and II was studied at 0-50° and 75-95% EtOH. At 10° and 85% EtOH, the solubility ratio of II to I is 3.8. I, 96% pure, was obtained from a mixture of I, II, and III by the following method. To 500 g. of a 1:1 mixture I (32%), II (20%), and III (40%) in MeOH was added 1 equivalent of H3PO4 (at <25°). To the precipitated salt was added just enough H2O to dissolve all of the phosphate of III. The remaining salt was decomposed in 20% NaOH yielding a 1:1 mixture of I and II. This was dissolved in 85% EtOH (1:1 ratio) and 1 equivalent of H2SO4 was added. The precipitated salt was recrystallized from 85% EtOH at 10°, decomposed with 10% base, extracted with benzene, and distilled to yield 58.8% I.

Popov, V. A.; Baboshin, Yu. V.; Belavina, I. G.; Cherkasov, N. Kh. published the article 《Conditions for extracting bases from the absorption fraction of coal tar》. Keywords: extraction coal tar base; absorption oil extraction coal tar base; sulfuric acid tar base extraction; phosphoric acid tar base extraction.They researched the compound: quinoliniumhydrogensulphate( cas:530-66-5 ).Category: thiazolidine. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:530-66-5) here.

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.
