Observations
Expt Table remarks: Step 1 'Found 0.1% crystal upon filter'; Step 3 'no turbidity in mass'. A stray reaction row is printed below the block: 'Step- 1 Phosphate ester 350, 65 oC, 25 min feed — Initially found turbidity / Final clear mass'; it has no Batch No and is not assigned to a numbered step. The Step 2 'Other' column carries an Iodine-value/Time ramp (65@2, 36.35@4, 27.5@5), kept out of the numbered results and noted here.
