industry in 1995 [Data from Ref. 2]
Solvent Amount. kg/year Solvent Amount. kg/year
benzene 6,000 ethylene glycol 29,000
n-butyl alcohol 44,000 hexane 15,000
sec-butyl alcohol 600 isopropyl alcohol 2,500
tert-butyl alcohol 2,000 methanol 300,000

chlorobenzene 4,000 tetrachloroethylene 26,000
chloroform 20,000 1,2,4-trichlorobenzene 10,000
cresol 7,000 1,1,1-trichloroethane 60,000
cyclohexane 12,000 trichloroethylene 54,000
1,4-dichlorobenzene 3,000 toluene 800,000
1,2-dichloroethane 3,000 xylene 470,000
dichloromethane 20,000 m-xylene 600
N,N-dimethylformamide 5,000 o-xylene 1,200
ethylbenzene 67,000 p-xylene 340
processes involved which use a wide variety of chemicals. Solvents are used for cleaning
and are components of product decoration materials.
Tables 14.27.1 and 14.27.2 give data on the reported releases and transfers of solvents
by the US stone, clay, glass, and concrete industry. Numerous solvents are used but most are
used in small quantities the only high volume ones being toluene, xylene, methanol,
1,1,1-trichloroethane, and methyl ethyl ketone. Although the industry does not release large
quantities of solvents, their total VOC contribution puts them second among the US industries.
Total releases and transfers are one of the smallest of all industries.
