Propyl propanoate (also known as propyl propionate and n-propyl propionate) is the organic compound with the molecular formula C 6 H 12 O 2. It is the ester of propanol and propionic acid. Like most esters, propyl propanoate is a colorless liquid with a fruity odor. The scent of propyl propionate is described as a chemically tinged pineapple or ...
2 CH 3 CH 2 CO 2 H → (CH 3 CH 2 CO) 2 O + H 2 O. Another routes is the Reppe carbonylation of ethylene with propionic acid and nickel carbonyl as the catalyst: [1] CH 2 =CH 2 + CH 3 CH 2 CO 2 H + CO → (CH 3 CH 2 CO) 2 O. Propionic anhydride has also been prepared by dehydration of propionic acid using ketene: [2] 2 CH 3 CH 2 CO 2 H + CH 2 ...
An isomeric form of propyl is obtained by moving the point of attachment from a terminal carbon atom to the central carbon atom, named isopropyl or 1-methylethyl. To maintain four substituents on each carbon atom, one hydrogen atom has to be moved from the middle carbon atom to the carbon atom which served as attachment point in the n -propyl ...
The propionate / ˈ p r oʊ p i ə n eɪ t /, or propanoate, ion is C 2 H 5 COO −, the conjugate base of propionic acid. It is the form found in biological systems at physiological pH. A propionic, or propanoic, compound is a carboxylate salt or ester of propionic acid. In these compounds, propionate is often written in shorthand, as CH 3 CH ...
If the alkyl group is not attached at the end of the chain, the bond position to the ester group is suffixed before "-yl": CH 3 CH 2 CH(CH 3)OOCCH 2 CH 3 may be called butan-2-yl propanoate or butan-2-yl propionate. [citation needed]. The prefix form is "oxycarbonyl-" with the (R') group preceding.
Isopropylamine can be obtained by reaction of isopropyl alcohol with ammonia in presence of a catalyst: [3] (CH 3) 2 CHOH + NH 3 → (CH 3) 2 CHNH 2 + H 2 O. Isopropylamine is a building block for the preparation of many herbicides and pesticides including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione.

The diisopropylbenzenes (DIPB) are organic compounds with the formula C 6 H 4 (CH(CH 3) 2) 2. Three isomers exist: 1,2- 1,3-, and 1,4-diisopropylbenzene. All are colorless liquids, immiscible in water, with similar boiling points. They are classified are aromatic hydrocarbons bearing a pair of isopropyl (CH(CH 3) 2) substituents. [1] DIPB has ...
