Pelargonic acid, also called nonanoic acid, is an organic compound with structural formula CH 3 (CH 2) 7 CO 2 H. It is a nine-carbon fatty acid. Nonanoic acid is a colorless oily liquid with an unpleasant, rancid odor. It is nearly insoluble in water, but very soluble in organic solvents.
Ammonium nonanoate is a nonsystemic, broad-spectrum contact herbicide that has no soil activity. [1] It can be used for the suppression and control of weeds, including grasses, vines, underbrush, and annual/perennial plants, including moss, saplings, and tree suckers.
4-Nonanoylmorpholine was first synthesized in 1954 by L. M. Rice, from morpholine and acyl chloride of pelargonic acid. It is a liquid insoluble in water and soluble in polar organic solvents (e.g. acetone, propanol, and dimethyl formamide) and fats. Its volatility is 27 mg/m 3 at 20 °C and 43 mg/m 3 at 35 °C.
It is dispensed from a handheld canister, in a liquid stream. It contains a 0.3% solution of pelargonic acid vanillylamide (PAVA), also called nonivamide, a synthetic capsaicinoid (analogue of capsaicin), in a solvent of aqueous ethanol. The propellant is nitrogen. This solution has been selected because this is the minimum concentration which ...
The nerve gas agent sarin, containing both C–P and F–P bonds, is a phosphonate. [citation needed] Phosphinates feature two P–C bonds, with the general formula R 2 P(=O)(OR'). A commercially significant member is the herbicide glufosinate. Similar to glyphosate mentioned above, it has the structure CH 3 P(O)(OH)CH 2 CH 2 CH(NH 2)CO 2 H.
Nonivamide, also called pelargonic acid vanillylamide or PAVA, is an organic compound and a capsaicinoid. It is an amide of pelargonic acid (n-nonanoic acid) and vanillyl amine . It is present in chili peppers , [ 2 ] but is commonly manufactured synthetically.
is the August equation, after the German physicist Ernst Ferdinand August (1795–1870). The August equation describes a linear relation between the logarithm of the pressure and the reciprocal temp. This assumes a temperature-independent heat of vaporization. The Antoine equation allows an improved, but still inexact description of the change ...
Some companies report their product as acid equivalent (ae) of glyphosate acid, or some report it as active ingredient (ai) of glyphosate plus the salt, and others report both. Given that each salt has its own molecular weight, the acid equivalent is a more accurate method of expressing and comparing concentrations.
