Sodium pentachlorophenolate synthesis

Yield:-

Reaction Conditions:

with sodium hydroxide in water; pH=9.5 - 10.5 at 80 - 85;

Steps:

1 Preparation of sodium pentachlorophenol liquid product
The long and short of sand and granular solid, sodium hydroxide, water, and into the reaction vessel, 80 - 85 °C under stirring, neutralization reaction, when the reaction solution pH of 9.5 to 10.5, the termination of the reaction, hydrogen sodium oxide in an amount of 1100Kg, sodium pentachlorophenol to give a crude solution, the concentration of the crude solution in this case 30%. adding water to sodium pentachlorophenol crude solution, using gravity concentration detector test liquid, when the concentration reaches 23 ± 0.5%, stop adding water to obtain a solution of sodium pentachlorophenol. Using automatic filling machine for sodium pentachlorophenol solution for packaging, using brown plastic bottles costumes, 500 grams per bottle.
