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.
tert-Butylthiol is the main ingredient in many gas odorant blends. [citation needed] It is always utilized as a blend of other compounds, typically dimethyl sulfide, methyl ethyl sulfide, tetrahydrothiophene or other mercaptans such as isopropyl mercaptan, sec-butyl mercaptan and/or n-butyl mercaptan, due to its rather high melting point of −0.5 °C (31.1 °F).
The prefixes sec (from "secondary") and tert (from "tertiary") refer to the number of additional side chains (or carbons) connected to the first butyl carbon. The prefix "iso" or "iso" means "isolated" while the prefix 'n-' stands for "normal". Butan-2-yl (sec-butyl) group is chiral. The carbon atom at position 2 is a stereocenter.
Butane-1-thiol, also known as butyl mercaptan, is a volatile, clear to yellowish liquid with a fetid (extremely foul-smelling) odor, commonly described as "skunk" odor. In fact, 1-butanethiol is structurally similar to several major constituents of a skunk's defensive spray but is not actually present in the spray. [ 4 ]
A human olfactory receptor, OR2T11, has been identified which, in the presence of copper, is highly responsive to the gas odorants (see below) ethanethiol and t-butyl mercaptan as well as other low molecular weight thiols, including allyl mercaptan found in human garlic breath, and the strong-smelling cyclic sulfide thietane.
Although addition of a hydrogen halide to an alkene is stereoselective, the symmetrical structure of 2-butene prevents an anti-Marknikov product from forming due to both sides of the double bond having the same stability. In addition, 2-chlorobutane can be synthesized in a substitution reaction by reacting 2-butanol with hydrochloric acid.
(R 1, R 2 and R 3 stands for organyl substituent or hydrogen in the case of R 1) In chemistry, an acyl group is a moiety derived by the removal of one or more hydroxyl groups from an oxoacid, [1] including inorganic acids. It contains a double-bonded oxygen atom and an organyl group (R−C=O) or hydrogen in the case of formyl group (H−C=O).
Methanethiol / ˌ m ɛ θ. eɪ n. ˈ θ aɪ. ɒ l / (also known as methyl mercaptan) is an organosulfur compound with the chemical formula CH 3 SH.It is a colorless gas with a distinctive putrid smell.
