Conclusion — verbatim from the source
“Product was Yellowish brownish flow able liquid”
pdf/9076 Data for Raven POC project/Old ELN/Lab Batch 15.pdf, page 2
Aim
To develop product equivalent to reference product
Observations
Step-A: Appearance was clear non yellowish. 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, yellowish in nature with viscosity. Mixed for 3 hrs then cooled to RT. Flow able yellowish liquid. Expt Table remarks: AV-34.2
