Reaction Yield at 99% target reaction yield: a worked example
Push target reaction yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it after synthesis, purification, distillation, or crystallization when yield drives cost, capacity, and customer supply.
The inputs for this scenario
- Accepted isolated product weight: 188 kg (unchanged)
- Theoretical (stoichiometric) product weight: 215 kg (unchanged)
- Target reaction yield: 99 % (raised for this scenario; the documented default is 88)
Working through the calculation
- Applying the documented formula (Reaction Yield rate = accepted isolated product weight ÷ theoretical product weight × 100) to the inputs above produces each figure below.
- At this operating point the engine returns 87.44 % for reaction yield rate, the number this scenario is built around.
- At this operating point the engine returns 11.56 points for reaction yield gap to target.
- At this operating point the engine returns 188 kg for accepted isolated product weight.
- At this operating point the engine returns 215 kg for theoretical product weight.
How this compares with the baseline
- Against the tool's baseline example, where target reaction yield sits at 88% and the headline result is 87.44 %, this scenario lands almost exactly on the baseline at 87.44 %.
- It divides accepted isolated product weight by theoretical product weight to give percent yield, then subtracts your target to show the gap in percentage points. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.
