2. GENERAL INFORMATION ON EXPOSURE
2.1 Production and import
The production volume of p-t-butylphenol in Japan is 5,000 tonnes/year in 1993. According to
ECDIN database, the production volume of USA is 11,000 tonnes/year in 1993. According to
IUCLID database, maximum production volume is 10,000 tonnes/year. Less than 5000 tonnes/year
are produced in France. Less than 1000 tonnes/year are sold to be used either as a chemical
intermediate for the production of vulcanization agents or as for the production of phenolic resins.
2.2 Use pattern
All of p-t-butylphenol produced in Japan is used as intermediate for resins, and no consumer uses are
reported. Most of the produced quantities are used on-site by the producer for the production of
phenolic resins in France.
2.3 Other information
None
