Does piperidine dissolve in water?

Piperidine

What is the pH of piperidine?

Piperidine for synthesis. CAS 110-89-4, pH 12.6 (100 g/l, H₂O, 20 °C).

Is piperidine polar or nonpolar?

Although piperidine is a common organic compound, it is best known as a representative structure element within many pharmaceuticals and alkaloids, such as natural-occurring solenopsins. A polar solvent that is capable of acting as a hydron (proton) donor.

Which is more basic pyridine or piperidine?

Pyridine is a substantially weaker base than alkylamines such as piperidine. The electron pair of pyridine occupies an sp2-hybridized orbital and lies closer to the nucleus than the electron pair in the sp3-hybridized orbital of alkylamines. The second nitrogen is structurally similar to the nitrogen atom of pyridine.

Which drug contain piperidine ring?

Use in pharmaceutical drugs Many pharmaceutical drugs contain a piperidine ring because the group tends to impart pharmacokinetics such as water solubility and bioavailability. Examples of drugs that contain piperidines include mesoridazine, thioridazine, haloperidol, droperidol, PCP, benperidol, and risperidone.

How do you dispose of piperidine?

Discharge into the environment must be avoided. Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations (see section 13). Avoid contact with skin and eyes.

What are the uses of piperidine?

Piperidine is used as a raw material for pharmaceuticals, agrochemicals, rubber chemicals, surface-active agents and other organic chemicals. A review on catalytic hydrogenation of pyridine was published in Advances in Catalysis.

Is piperidine a weak base?

Piperidine is the most basic (conjugate acid pKa = 11.2). In pyrrole is a very weak base (conjugate acid pKa = -4). The N lone pair is involved in the 6π electron aromatic system. Protonation will destroy the aromaticity of the 6π electron aromatic system and this makes it an unfavourable process.

Is piperidine a strong or weak base?

Piperidine is the stronger base, with a pKb about 4. The pKb for morpholine would be about 6. In aqueous solution at pH 9, which amine would exist mainly as an ammonium ion? Piperidine remains protonated up to pH about 10.

Is piperidine an acid or base?

Piperidine is the most basic (conjugate acid pKa = 11.2).

What is the boiling point of piperidine in water?

Piperidine appears as a clear colorless liquid with a pepper-like odor. Less dense than water, but miscible in water. Will float on water. Flash point 37°F. Melting point -15.8°F (-9°C). Boiling point 222.8°F (106°C).

How many methylene bridges are there in piperidine?

From Wikipedia, the free encyclopedia Piperidine is an organic compound with the molecular formula (CH 2) 5 NH. This heterocyclic amine consists of a six-membered ring containing five methylene bridges (–CH 2 –) and one amine bridge (–NH–). It is a colorless liquid with an odor described as objectionable, and typical of amines.

What is the molecular weight of piperidine 110-89-4?
