Piperidine is used as a solvent and as a base. The same is true for certain derivatives: N-formylpiperidine is a polar aprotic solvent with better hydrocarbon solubility than other amide solvents, and 2,2,6,6-tetramethylpiperidine is a highly sterically hindered base, useful because of its low nucleophilicity and high solubility in organic ...
Piperidine is produced by hydrogenation of pyridine with a nickel-, cobalt-, or ruthenium-based catalyst at elevated temperatures. [100] The hydrogenation of pyridine to piperidine releases 193.8 kJ/mol, [ 101 ] which is slightly less than the energy of the hydrogenation of benzene (205.3 kJ/mol).
Piperidine, a cyclic six-membered amine that results from hydrolysis of piperine; Piperic acid, the carboxylic acid also derived from hydrolysis of piperine; Capsaicin, the active piquant chemical in chili peppers; Allyl isothiocyanate, the active piquant chemical in mustard, radishes, horseradish, and wasabi
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.
N-Formylpiperidine is an organic compound with the formula C 6 H 11 NO. It is the amide of formic acid and piperidine.It can be used as a polar aprotic solvent, with better hydrocarbon solubility than other amide solvents such as dimethylformamide (DMF). [1]
Hansen solubility parameters were developed by Charles M. Hansen in his Ph.D thesis in 1967 [1] [2] as a way of predicting if one material will dissolve in another and form a solution. [3] They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way.
The ability of one compound to be dissolved in another is known as solubility; if this occurs in all proportions, it is called miscible. In addition to mixing, the substances in a solution interact with each other at the molecular level. When something is dissolved, molecules of the solvent arrange around molecules of the solute.
