Description of key information

The particle size distribution of test item 2-tert-butylhydroquinone (CAS No. 1948-33-0 ) was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was found to be in the range of 150 micron to 25 micron.

Additional information

The particle size distribution of test item 2-tert-butylhydroquinone (CAS No. 1948-33-0 ) was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was found to be in the range of 150 micron to 25 micron.

From other experimental reports, the particle size distribution (granulometry) of 2 -tert-butylhydroquinone by the sieve method was found to range from 75 micro meter to 710 micrometer. Majority of the particles (77%) were between 180 to 500 micrometer range.
