Aim
Handwritten lab-note for a BYK 9076 analogue batch (9076 Exp 48-60 series): Step-I phosphate ester of the polyol with P2O5, Step-II acylate/acrylate intermediate from SP-18 (or Lupasol G-20) with 2-ethyl hexyl acrylate/acylate, Step-III neutralisation of the phosphate ester with the acylate intermediate.
Observations
Step I: Brown particles, slight foam, AV-52, Residue - sticks on wall. Step II: Yellowish tincture, clear mass, IU - 32.3, IU - 17.6. Step III: Foaming, turbidity, Non Uniform mass, AU - 43, Amine 25.7. Charged - LUB 1010 - 200 gm Feed of P205 - 10 gm Over 10-15 min. / slow dispersion. Brown particles, slight foam /, AV-52, Residue - sticks on wall Charged Lupasol-G-20 15gm. Feed of (Acrylate + AIBN) mix started Yellowish tincture / clear mass, Yellowish - clear mass. IU - 32.3 / clear mass. IU - 17.6 -, clear mass / yellow tincture. Charged Acrylate - 15gm. Feed of phosphate Ester - 7 min. foaming / turbidity, Non Uniform. mass., AU - 43 / Amine 25.7
Procedure summary
Step I: Phosphate ester synthesis. Step II: Acylate intermediate synthesis using Lupasop G-20 and AIBN. Step III: Neutralization.
