Show me batch 48.21 Aug 01:15
I have the complete record. Here's batch 48.
Batch 48 (LBN 48 / Sample P 76 B.NO 48) — synthesis record, scientist "vnmr1".
Process: Three-step route (phosphate ester → acrylate intermediate → neutralization), all under N2, final product filtered through Nylon Mesh.
Final product (neutralized) measurements: AV 44.36, HV 46.58, SAP 62.14, Amine 36.25, IV 2.58.
Critical parameters vs reference targets (30.1 amine / 43.2 av are the BYK-9076 target pair, labeled as targets): two rows — (Amine 36.25 vs 30.1; AV 44.36 vs 43.2) and (Amine 20.2 vs 30.1; AV 46.5 vs 43.2).
Application test (P 76 B.NO 48, vs same-day BYK-9076 standard): Viscosity 31 sec (standard 31), Gloss 34 (standard 34), Colour Strength 1 (1), Resolubility 4 (4), Transparency Transparent (Ref as Std); verdict field is null (no pass/fail recorded).
Outcome: status "ok" — "Tested over pigment Black, Blue, Violet-23/27 etc All having matching resolubility while reduced gloss in violet; Tested on Violet 23 resolubility ok" [LBN 48.pdf, page 2].
Date conflict (unresolved): NMR plots dated "Dec 25 2025"; experiment table row dated "26.6.25". Reported as-is.
Analytical: 1H & 13C NMR (FS + zoom1/zoom2) in CDCl3, 25 Dec 2025.

- Step 1: Vicaspin LUB 1010 (R225100845) Bu-EO-PO HV-62.3/MW-900 (178 g) heated to 50 °C, P2O5 added, digested 3 h at 70-75 °C. AV-51.87, Mono-22.56, Di-48.93, Free acid-1.096.
