After a reaction the previously prepared compound was turned into a bit larger molecule that was purified in a Soxhlet extractor. The methylene chloride that was used as a solvent extracted my compound from the upper paper thimble. The extraction was continued till no color was detected in the upper part of the extractor.
Soxhlet extractor is a piece of laboratory apparatus invented in 1879 by Franz von Soxhlet. It was originally designed for the extraction of a lipid from a solid material. Typically, a Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for unmonitored and unmanaged operation while efficiently recycling a small amount of solvent to dissolve a larger amount of material.
“You were afraid to nurse your young
lest fallen breast offend your master’s sight
and he should flee to firmer loveliness.
And so you passed them, your children, on to me.
Flesh that was your flesh and blood that was your blood
drank the sustenance of life from me.
And as I gave suckle I knew I nursed my own child’s enemy.
I could have lied,
told you your child was fed till it was dead of hunger.
But I could not find the heart to kill orphaned innocence.
For as it fed, it smiled and burped and gurgled with content
and as for color knew no difference.
Yes, in that first while
I kept your sons and daughters alive.
But when they grew strong in blood and bone
that was of my milk
taught them to hate me.
Put your decay in their hearts and upon their lips
so that strength that was of myself
turned and spat upon me,
despoiled my daughters, and killed my sons.
You know I speak true.“
