procedure summary

Step-I: Charged LUB 1010 (178 gm) at RT-50/N2, fed P2O5 over 1.5 hrs at 75-77°C/N2, held at 77°C for 1 hr. Step-II: Charged Sp-18 at 75-79°C/N2, fed 2-ethyl hexyl Acylate over 2 hrs at 78-79°C/N2, held 5.5 hrs to clear transparent. Step-III: Charged Acylate Intermediate, fed phosphate ester (85%) over 25 min at 55-59°C/N2, held 1.5 hrs. Batch 48Q: Charged Acylate Intermediate (15%) + DMS (0.5%), then phosphate (85%) at 55-75°C/N2.
