223Bromine By Charles L. Klingman1 The bromine industry displayed surprising vitality in 1972. In spite of efforts to reduce atmospheric pollution from automobile exhausts, the predicted reduction in use of tetraethyl lead as an antiknock and ethylene dibromide as a lead scavenger in gasoline did not occur. There was, in fact, an increase of more than 13% in ethylene dibroniide production in the United States, compared with that of 1971. The increase was caused, to some extent, by increased exports of antiknock compounds, which include ethylene dibromide particularly to the United Kingdom and Brazil.2 In 1972 total bromine production increased by 30,918,000 pounds over 1971 production. It is probable, however, that the large 1972 gain will not be maintained in 1973 and subsequent years. DOMESTIC PRODUCTION The State of Arkansas continued to gain in bromine production, with 1972 output about 17% above that of 1971. Michigan had a 6.6% reduction in output. The high bromine concentration and large reserves of Arkansas underground brine makes this State a logical location for future expansion. The brine wells of Michigan, by comparison, were not as free-flowing and had lower bromine content. Therefore, more wells had to be drilled and more brine had to be handled in Michigan per pound of bromine produced. About 10% of the total bromine pro~ duced was sold in the elemental state to nonmanufacturers of bromine compounds. The fraction of the bromine production not used in the manufacture of compounds had remained relatively constant over the years. The rate of bromine production in 1972 was 9% higher than that of 1971. The historic growth rate for the Industry was about 7% per annum. Table 1 presents data only on elemental bromine. The bromine classified as "used" in table 1 is the same bromine that appears in table 2 as the "bromine content" of manufactured compounds, except for processing losses and variations in stocks on hand. Table 2 deals exclusively with bromine compounds manufactured for the end use market. In 1972 there were 10 bromine producing plants in three States operated by 1 Physical scientist, Division of Nonmetallic Minerals. 2 Chemical Engineering News.
