Recycling of triethyl phosphate
Thread Content
Dear teachers, we use triethyl phosphate as a solvent in the production process. Since triethyl phosphate is relatively expensive, we want to recycle it. The solvent contains sodium chloride, water, hydrochloric acid, and phosphoric acid – how can we isolate triethyl phosphate from it? Please help if you can; if there is a good method, I am willing to offer fifty wealth as a reward.
Direct stratification won’t work; if there is a small amount of water, a salt column can be used to absorb it
The key is that triethyl phosphate and water are miscible
I have a 50% aqueous solution of triethyl phosphate; I’m not sure if anyone would be interested in it
