TEST METHOD: The particle size distribution was determined for test item o-anisic acid, CAS No 579-75-9.The test item is a alomost white odourless powder. (Colour and form of the chemical).The particle size distribution was determined with the help of Rotap sieve shaker. For this method,calibrated sieves were stacked with the coarsest opening sieve at the top of the stack and finest opening sieve at the bottom. 10.009 gm test item was weighed and put in the coarsest opening sieve placed at the top of the stack, covered with the lid. The stack was fitted in sieve shaker and was shaken for 10 minutes. The material was emptied from the above coarsest sieve into a pre-weighed petridishes. A soft bristle brush was used to

remove all the particles. The quantity obtained from the 1st sieves was weighed, and transferred to original apparatus. The above procedure was repeated for each sieve. Weight obtained from each sieve was then divided by the Test item quantity retained after sieving and percentage of each sieve was calculated

Conclusions:

The particle size distribution of chemical 2-methoxybenzoic acid (CAS No. 579-75-9 ) was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was found to be in the range of 150 micron to 53micron.

Executive summary:

The particle size distribution of chemical 2-methoxybenzoic acid (CAS No. 579-75-9 ) was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was found to be in the range of 150 micron to 53micron.
