Propylamine, also known as n-propylamine, is an amine with the chemical formula CH 3 (CH 2) 2 NH 2. [1] It is a colorless volatile liquid. [2] Propylamine is a weak base. Its K b (base dissociation constant) is 4.7 × 10 −4.
CH 3 CHO + NH 3 + H 2 → CH 3 CH 2 NH 2 + H 2 O. Ethylamine can be prepared by several other routes, but these are not economical. Ethylene and ammonia combine to give ethylamine in the presence of a sodium amide or related basic catalysts. [5] H 2 C=CH 2 + NH 3 → CH 3 CH 2 NH 2. Hydrogenation of acetonitrile, acetamide, and nitroethane ...
[c] [2] For example, a hypothetical weak acid having K a = 10 −5, the value of log K a is the exponent (−5), giving pK a = 5. For acetic acid, K a = 1.8 x 10 −5, so pK a is 4.7. A higher K a corresponds to a stronger acid (an acid that is more dissociated at equilibrium).
Hexylamine or n-hexylamine is a chemical compound with the formula CH 3 CH 2 CH 2 CH 2 CH 2 CH 2 NH 2. This colorless liquid is one of the isomeric amines of hexane. At standard temperature and pressure, it has the ammonia/bleach odor common to amines and is soluble in almost all organic solvents.
n-Butylamine is an organic compound (specifically, an amine) with the formula CH 3 (CH 2) 3 NH 2. This colourless liquid is one of the four isomeric amines of butane, the others being sec-butylamine, tert-butylamine, and isobutylamine. It is a liquid having the fishy, ammonia-like odor common to amines.
Propanamide has the chemical formula CH 3 CH 2 C=O(NH 2). [1] It is the amide of propanoic acid. This organic compound is a mono-substituted amide. [2] Organic compounds of the amide group can react in many different organic processes to form other useful compounds for synthesis.
Dipropylamine is an organic compound with the formula (CH 3 CH 2 CH 2) 2 NH. It is classified as a secondary amine. It is a colorless liquid with a "fishy" odor. It is a precursor to various herbicides such as trifluralin, oryzalin, and vernolate. [3] Trifluralin, an herbicide containing a dipropylamino group
See Amino acid for the pK a values of all amino acid side chains inferred in such a way. There are also numerous experimental studies that have yielded such values, for example by use of NMR spectroscopy. The table below lists the model pK a values that are often used in a protein pK a calculation, and contains a third column based on protein ...
