Piperidine is widely used to convert ketones to enamines. [23] Enamines derived from piperidine are substrates in the Stork enamine alkylation reaction. [24] Upon treatment with calcium hypochlorite, piperidine converts to N-chloropiperidine, a chloramine with the formula C 5 H 10 NCl.
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.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Among other substances, he separated from the oil a colorless liquid with unpleasant odor, from which he isolated pure pyridine two years later. He described it as highly soluble in water, readily soluble in concentrated acids and salts upon heating, and only slightly soluble in oils.
Olive oil, for drizzling. 2 to 3 tablespoons grated Parmesan cheese, divided, plus more as needed. About 1/3 cup shredded mozzarella, plus more as needed. 2 slices prosciutto.
Hexane (/ ˈ h ɛ k s eɪ n /) or n-hexane is an organic compound, a straight-chain alkane with six carbon atoms and the molecular formula C 6 H 14. [ 7 ] Hexane is a colorless liquid, odorless when pure, and with a boiling point of approximately 69 °C (156 °F).
Lobeline is a piperidine alkaloid found in a variety of plants, particularly those in the genus Lobelia, including Indian tobacco (Lobelia inflata), Devil's tobacco (Lobelia tupa), great lobelia (Lobelia siphilitica), Lobelia chinensis, and Hippobroma longiflora. In its pure form, it is a white amorphous powder which is freely soluble in water.
