Batch 48 (record
Synthesis — Three-step process under N2, scientist vnmr1, record date 26.6.25:
1. Phosphate ester: Vicaspin LUB 1010 (R225100845) Bu- EO-PO HV-62.3/MW-900 heated to 50 °C, P2O5 added, digested 3 h at 70–75 °C.
2. Acrylate intermediate: Epomine SP-018 at 78–81 °C, 2-ethyl hexyl acrylate fed over 2 h, continued 5 h (IV-26.1 @ 5.5 h).
3. Neutralization: acrylate intermediate (13%) + phosphate ester (87%) at 56 °C, 3 h, filtered through Nylon Mesh.
Note: a downstream modification labelled LBN-48 (Q) also exists (acrylate 0.15, dimethyl sulphate 0.005, phosphate 0.85; staged 65–75 °C/1 h then 55–60 °C/2.5 h).
Two scale variants (conflicting, both reported):
Target pair (reference values, not measured): amine 30.1, AV 43.2. The 44.36/36.25 set is closer to target than the 46.5/20.2 set.
Application tests (NC-PU ink, trial 31.10.2025, vs same-day BYK-9076 Standard) — gloss inferior vs that day's standard across all pigments: Black gloss 30.9 (std 31), Blue 34.8 (std 34), Violet-27 4.6 (std 5.3), Violet-23 53.3 (std 62). Resolubility 3–4 vs std 4.
Analytical: 6 NMR spectra (1H/13C, FS + zoom1/zoom2) in CDCl3, 25Dec2025.
Confidence: medium — handwriting-derived values, a second (LBN 49) scale variant, and a separate LBN-48 (Q) downstream step co-exist in the record.
