No separate ELN report exists for batch 27. Here is what the records actually contain.

## Batch 27 — no standalone ELN report in this data drop

There is no ELN/notebook report file for batch 27. All five batch-27 records (27 A, B, C, D, E) carry only one linked document, the summary table, at role summary_table, linked by alias match (docs/Project Expt Report/28112025 9076 Expt Table 2025.xls, sheet 9076_Experiments, batch block '27 X'). A full-text search for batch-27-related ELN/report/notebook text returned nothing for 27. So what follows is the summary-table content, not a raw ELN.

Common to all five: Step 1 = Vicasurf-1010 1700 g + Phosphorous pentaoxide 64.09 g, 40 oC, Feed 0.4, 4.5 h N2, A.V. 38.1; remark "Found 0.1% crystal upon filter". They differ in Step 2/3:

• 27 A: Step 2 Epomine SP-018 105 g + 2 ethyl hexyl acrylate 245 g (AV 0.35, Amine 272, IV 27.5); Step 3 mix 85/15 (AV 36.61, Amine 40.1). Note: merged from two fragments, so steps appear duplicated.
• 27 B: same Step 2; Step 3 mix 80/20 (AV 33.7, Amine 42.3).
• 27 C: same Step 2; Step 3 mix 75/25 (AV 29.1, Amine 52.27); "clear uniform mass".
• 27 D: Step 2 Lupasol G-20 105 g + 2 ethyl hexyl acrylate 245 g (AV 0.35, Amine 281.5, IV 17.7); Step 3 mix 85/15 (AV 33.1, Amine 34.89); stray unassigned row "Step-1 Phosphate ester 350, 65 oC, 25 min feed".
• 27 E: Step 2 Lupasol G-20 17.26 g, 65-71 oC 3 h (AV 29.98, Amine 41.72); no Step 3.

Dates/outcome: none recorded for any of the five.
