Triphenyl Phosphite Recipe

Phenol ${?}_{(I)}+PC{l}_{3(I)}TP{P}_{(l)}+HC{l}_{(g)}$

Charge $12000kg$ of phenol to a batch reactor.

a$)$ Raise the temperature to $90$deg.

Meter in $5000kg$ of Phosphorus Trichloride $(PC{l}_3)$ at $50k\frac{g}{m}in.$

a$)$ Maintain temperature, Control pressure at $3$ psig as $HC{l}_g$ is released

Lower pressure to $0$ psig while holding temp. at $90C$ for $1$ hour $($i$.$e$.$ in parallel$).$

Raise temperature to $150C.$ After reaching $150C,$ wait $1$ hour.

Cool to $50$degC and then sample. If Acid level too high, return to $4.$
