Applicant's summary and conclusion
- Conclusions:
- The particle size distribution (granulometry) of 4-aminotoluene-2-sulphonic acid by the sieve analysis method was found to be in the range of 53 micrometer to 300 micrometer. Majority of the particles were found to be in the size more than 150 (30.65%) and 75(19.91%) micrometer in size.
- Executive summary:
The particle size distribution (granulometry) of 4-aminotoluene-2-sulphonic acid by the sieve analysis method was found to be in the range of 53 micrometer to 300 micrometer. Majority of the particles were found to be in the size more than 150 (30.65%) and 75 (19.91%) micrometer in size.
