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 ...
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.
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.

Due to its poor solubility in water, piperine is typically extracted from black pepper by using organic solvents like dichloromethane. [5] The amount of piperine varies from 1–2% in long pepper, to 5–10% in commercial white and black peppers.
In a statement, a spokesperson for the Secretary of the Air Force tells Scripps News that the potential move of the Air National Guard units into the U.S. Space Force is "to ensure the mission ...
One of the primary reasons the Space Force was created was to consolidate space forces from across the U.S. Air Force, U.S. Army, and U.S. Navy. [37] In 2020, the Space Training and Readiness Delta (Provisional) was established to form the foundation for Space Training and Readiness Command and incorporate Air Force space units spread across ...
The Malabar Transmitter Annex is currently used as an auxiliary communications annex in support of space activities for NASA and the U.S. Space Force. The facility is under the control of the Space Launch Delta 45 as an annex of Patrick Space Force Base. The annex was originally established as a naval airfield in 1943.
