Quality Control of Aluminum(III) sulfate xhydrate. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Aluminum(III) sulfate xhydrate, is researched, Molecular Al2H8O13S3, CAS is 17927-65-0, about A novel photoinitiated approach for preparing aluminum diethylphosphinate under atmospheric pressure. Author is Yang, Li; Han, Xin Yu; Tang, Xue Jiao; Han, Chang Xiu; Zhou, Yi Xiao; Zhang, Bao Gui.

A novel preparation of aluminum diethylphosphinate (AlPi) was carried out with free-radical addition reaction by means of UV-irradiation under atm. pressure. A solution of sodium hypophosphite was treated with ethylene and irradiated with UV light in the presence of an amount of photoinitiator effective to initiate the free-radical reaction between the hypophosphite anion and the double bond of the ethylene mol. The ethylene was micro-bubbled into the reaction mixture with the addition of the photoinitiator, and the gas-liquid contact surface and the photoinitiator concentration in the gas-liquid interface were increased largely. The yield of the final product could be improved to about 96%. The contents of P, Al in samples were detected by ICP, and the mol. structure of the samples was confirmed by 31P NMR, 1H NMR and FTIR spectroscopic anal. Thermal stability of the final products was investigated in detail by TG-DTA.

From this literature《A novel photoinitiated approach for preparing aluminum diethylphosphinate under atmospheric pressure》,we know some information about this compound(17927-65-0)Quality Control of Aluminum(III) sulfate xhydrate, but this is not all information, there are many literatures related to this compound(17927-65-0).

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Configuration of the camphoric acids》. Authors are Walker, James; Wood, John K..The article about the compound:(1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acidcas:560-09-8,SMILESS:CC1(C)[C@@H](CC[C@]1(C)C(O)=O)C(O)=O).Reference of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid. Through the article, more information about this compound (cas:560-09-8) is conveyed.

The molecule of camphoric acid contains two, and only two, asymmetric carbon atoms, that these carbon atoms are links in a closed carbon chain, and that each of them has a carboxyl group attached to it. It is further known that the asymmetric carbon atoms are not similar to each other, so that there can be no optical inactivity by internal compensation. To distinguish between these two asymmetric atoms, the prefixes ortho- and allo-, which are commonly used in application to the two carboxyl groups are employed. A discussion on the asymmetric carbon atom to which the ortho-carboxyl group is attached as the ortho-carbon atom, and of that to which the allo-carboxyl group is united as the allo-carbon atom, is presented.

There is still a lot of research devoted to this compound(SMILES：CC1(C)[C@@H](CC[C@]1(C)C(O)=O)C(O)=O)Reference of (1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid, and with the development of science, more effects of this compound(560-09-8) can be discovered.
