Like other butanols, butan-2-ol has low acute toxicity. The LD 50 is 4400 mg/kg (rat, oral). [6]Several explosions have been reported [7] [8] [9] during the conventional distillation of 2-butanol, apparently due to the buildup of peroxides with the boiling point higher than that of pure alcohol (and therefore concentrating in the still pot during distillation).
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).
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.

Alcohols are then classified into primary, secondary (sec-, s-), and tertiary (tert-, t-), based upon the number of carbon atoms connected to the carbon atom that bears the hydroxyl functional group. The respective numeric shorthands 1°, 2°, and 3° are sometimes used in informal settings. [23] The primary alcohols have general formulas RCH 2 OH.
Alcohol. It might seem obvious, but even small amounts of alcohol can have serious effects on a dog’s liver and brain. So, no sips of beer or wine for Fido! 7. Macadamia Nuts.

From April 2009 to December 2012, if you bought shares in companies when Michael E. O’Neill joined the board, and sold them when he left, you would have a 22.1 percent return on your investment, compared to a 67.8 percent return from the S&P 500.
