1,4-Dichlorobutane is a chloroalkane with the molecular formula (CH 2 CH 2 Cl) 2. It is one of several structural isomers of dichlorobutane. They are all colorless liquids of low flammabiltity and of interest for specialized synthetic uses.
A new British Standard (2020) gives recommendations and guidance on the development of a Water Safety Plan (WSP). The standard is intended to be used as a code of practice to demonstrate current good practice and compliance. BS 8680:2020 Water quality. Water safety plans. Code of practice [7]
Water resource policy, sometimes called water resource management or water management, encompasses the policy-making processes and legislation that affect the collection, preparation, use, disposal, and protection of water resources. [1]
There are six substances encompassed under this general name - in fact, there are much more than that. 1,1 dichlorobutane; 1,2 dichlorobutane (2 optical isomers); 1,3 dichlorobutane (2 optical isomers); 1,4 dichlorobutane; 2,2, dichlorobutane; 2,3 dichlorobutane (3 optical isomers); 1,1 dichloro methyl propane (2 optical isomers); 1,2 dichloro methyl propane (2 optical isomers); 1,3 dichloro ...
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.
The most common use of 1,2-dichloroethane is in the production of vinyl chloride, which is used to make polyvinyl chloride (PVC) pipes, furniture and automobile upholstery, wall coverings, housewares, and automobile parts. [4] 1,2-Dichloroethane is also used generally as an intermediate for other organic chemical compounds, and as a solvent.
1,2-Dichloropropane is an intermediate in the production of perchloroethylene and other chlorinated chemicals. [4] It was once used as a soil fumigant , chemical intermediate, as well as an industrial solvent and was found in paint strippers, varnishes, and furniture finish removers but some of these uses have been discontinued.
The agency, along with the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Water Alliance have provided webinars and other guidance for using a One Water approach for water management. [11] The U.S. Water Alliance also has more initiatives to support One Water, including the One Water Council to bring organizations together ...
