Benzonatate → Benzonatate calcium silicate

참여 물질

반응 단계

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