“Product was Yellowish flow able liquid”
[Lab Batch 10.pdf, page 2]
Aim
To develop product equivalent to reference product
Observations
Step-A: Appearance was yellowish with slight gripped in viscosity. Upon digestion cooled to RT. Step-B: initially found clear reaction mass , later on changed to yellowish in nature. Built viscosity at end of reaction. Step-C: initially found clear reaction mass , later on changed to slight turbid yellowish in nature with viscosity. Expt Table remarks: Initial feed of Step 10 B slowly found clear transparent mass ( still 20%) then slowly increased turbidity. Upon total feed reaction mass became viscous non flowable yellowish white mass. AV-55 Expt Table remarks: Tested sample and found good results likely resolubility/ tinting strenghth/ gloss etc. with respect to reference product.

To main reactor added Vicasurf 1010 under stirring and nitrogen atmosphere temp. 40 deg increased temp slowly with addition of P- pentaoxide. Upon feed completion temp raised to 75 deg C and digested for 2-3 hrs. Appearance was yellowish with slight gripped in viscosity. Upon digestion cooled to RT. [ELN]

To main reactor added Step- B reaction mass (20%) - reaction mass under stirring and nitrogen atmosphere temp. 55 deg Started slowly addition of Step- A (80%) reaction mass in it. initially found clear reaction mass , later on changed to slight turbid yellowish in nature with viscosity. Mixed for 3 hrs then cooled to RT. [ELN]
Initial feed of Step 10 B slowly found clear transparent mass ( still 20%) then slowly increased turbidity. Upon total feed reaction mass became viscous non flowable yellowish white mass.
