  2. Butyl group - Wikipedia

    en.wikipedia.org/wiki/Butyl_group

    According to IUPAC nomenclature, "isobutyl", "sec-butyl", and "tert-butyl" used to be allowed retained names.The latest guidance changed that: only tert-butyl is kept as preferred prefix, all other butyl-names are removed.

  3. Butanol - Wikipedia

    en.wikipedia.org/wiki/Butanol

    Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C 4 H 9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; [1] all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, sec-BuOH, i-BuOH, and t-BuOH).

  4. Isobutyl acetate - Wikipedia

    en.wikipedia.org/wiki/Isobutyl_acetate

    A common method for preparing isobutyl acetate is Fischer esterification, where precursors isobutyl alcohol and acetic acid are heated in the presence of a strong acid. Isobutyl acetate has three isomers: n-butyl acetate, tert-butyl acetate, and sec-butyl acetate, which are also common solvents.

  5. Butyl acetate - Wikipedia

    en.wikipedia.org/wiki/Butyl_acetate

    n-Butyl acetate is an organic compound with the formula CH 3 CO 2 (CH 2) 3 CH 3. A colorless, flammable liquid, it is the ester derived from n- butanol and acetic acid . It is found in many types of fruit, where it imparts characteristic flavors and has a sweet smell of banana or apple.

  6. Alkyl group - Wikipedia

    A dialkyl ether is an ether with two alkyl groups, e.g., diethyl ether O(CH 2 CH 3) 2. In medicinal chemistry ... butyl isobutyl ... (−CH 3) 2: 2-methylpropyl sec ...

    The side chains are: an ethyl- at carbon 4, an ethyl- at carbon 8, and a butyl- at carbon 12. Note: the −O−CH 3 at carbon atom 15 is not a side chain, but it is a methoxy functional group. There are two ethyl- groups. They are combined to create, 4,8-diethyl. The side chains are grouped like this: 12-butyl-4,8-diethyl.

  8. sec-Butyl acetate - Wikipedia

    en.wikipedia.org/wiki/Sec-Butyl_acetate

    sec-Butyl acetate, or s-butyl acetate, is an ester commonly used as a solvent in lacquers and enamels, where it is used in the production of acyclic polymers, vinyl resins, and nitrocellulose. [3] It is a clear flammable liquid with a sweet smell.

  9. Living cationic polymerization - Wikipedia

    The method was developed starting in the 1970s and 1980s with contributions from Higashimura on the polymerization of p-methoxystyrene using iodine or acetyl perchlorate, [3] on the polymerization of isobutyl vinyl ether by iodine [4] and with Mitsuo Sawamoto by iodine/HI [5] and on the formation of p-methoxystyrene - isobutyl vinyl ether block copolymers.
