Commercial production of ethylene glycol in the United States began in 1925 (McClelland and Rector 1951; Miller 1966). The reported U.S. production volume was 2.189 million pounds (993 metric tons) during that year (McClelland and Rector 1951). Large-scale commercial use of ethylene glycol as an antifreeze began in 1930; this use led to a strong demand for ethylene glycol, especially during and after World War II (Brown et al. 1980; McClelland and Rector 1951). Production volume information is not available for this period. By 1950, the U.S. production volume had risen to 510 million pounds (230,000 metric tons) (Brown et al. 1980; McClelland and Rector 1951). Production continued to rise steadily, reaching approximately 900,000 metric tons by 1968 (Brown et al. 1980). Ethylene glycol production rose more dramatically in late 1960s and early 1970s due to the additional demand for use of this substance in the manufacturing of polyester fiber and film (Brown et al. 1980; CMR 1972, 1975). Production in 1970 was approximately 1,400,000 metric tons (Brown et al. 1980). Production fluctuated between 1,500,000 and 1,800,000 metric tons over the next 18 years, reaching 1,820,000 metric tons by 1978 (Brown et al. 1980).
