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 ...
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.

Isopropylmagnesium chloride is an organometallic compound with the general formula (CH 3) 2 HCMgCl. This highly flammable, colorless, and moisture sensitive material is the Grignard reagent derived from isopropyl chloride. It is commercially available, usually as a solution in tetrahydrofuran.
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.
Follow the 10-3-2-1 sleep rule. This is straightforward, logical advice, and it really works: No caffeine 10 hours before bed. No food or drink 3 hours before.
C 6 H 4 (CH(CH 3) 2) 2 + C 6 H 6 → 2 C 6 H 5 CH(CH 3) 2. The 1,3- and 1,4- isomers are mainly of interest as precursors to the respective dihydroxylbenzene derivatives, which exploits the Hock rearrangements. All three isomers form hydroperoxides, as is implicit in the Hock rearrangement, which are of interest as radical initiators for ...
