Applicant's summary and conclusion

Conclusions:
The particle size distribution (granulometry) of 2,2,2-trifluoroacetamide by the sieve analysis method was found to be in the range of 150 micrometer to 600 micrometer. Majority of the particles were found to be in the size of 600 (44.03%) micrometer in size.
