Benzonatate → Benzonatate calcium silicate

참여 물질

반응 단계

Using the ingredients in the immediately preceding table, calcium silicate was mixed at slow speed in a high shear granulator (Impeller: 250 rpm and Chopper: 3200 rpm). Benzonatate was added to it at slow speed (Impeller: 250 rpm and Chopper: 3200 rpm) at a rate of approximately 7 g/minute. The benzonatate-calcium silicate adsorbate granules formed were passed through 425 micron screen. Using the assay described herein, the amount of benzonatate was determined to be 60.66 wt % benzonatate based on the total weight of the adsorbate.
