It is somewhat soluble in water and readily evaporates into the air. Bromoform is the main trihalomethane produced in beachfront salt water swimming pools with concentrations as high as 1.2 ppm (parts per million). Concentrations in freshwater pools are 1000 times lower. [9] Occupational skin exposure limits are set at 0.5 ppm. [10]

The first step is the liquid- or vapour-phase chlorination of butadiene to a mixture of 3,4-dichlorobut-1-ene and 1,4-dichlorobut-2-ene (both isomers). In the second step, the mixture of 1,4-dichlorobut-2-ene and 3,4-dichlorobut-1-ene is isomerized to 3,4-dichlorobut-1-ene by heating to temperatures of 60–120 °C in the presence of a catalyst.
Chlorobutanol (trichloro-2-methyl-2-propanol) is an organic compound with the formula CCl 3 C(OH)(CH 3) 2. The compound is an example of a chlorohydrin. The compound is a preservative, sedative, hypnotic and weak local anesthetic similar in nature to chloral hydrate. It has antibacterial and antifungal properties. [1]
This is because 2-chlorobutane possesses two different sets of β-hydrogens at the first and third carbons respectively, resulting in 1-butene or 2-butene. It is important to note that as a secondary alkyl halide, both E2 and Sn2 reactions are equally likely when reacting with a substance that can act as both a base and a nucleophile.

In the similar substitution of 1-chloro-3-methyl-2-butene, the secondary 2-methyl-3-buten-2-ol is produced in a yield of 85%, while that for the primary 3-methyl-2-buten-1-ol is 15%. Allylic shifts occur because the transition state is an allyl intermediate. In other respects they are similar to classical nucleophilic substitution, and admit ...
2,3-Dichlorobutadiene is a chlorinated derivative of butadiene. This colorless liquid is prone to polymerization, more so than 2-chlorobutadiene. It is used to produce specialized neoprene rubbers. It can be prepared by the copper-catalyzed isomerization of dichlorobutynes. Alternatively dehydrochlorination of 2,3,4-trichloro-1-butene: [1]
