Title: Yield
Post by: Emenike on November 03, 2019, 06:36:52 PM

In synthetic chemistry, much care is taken in maximising yield. Why is it then, that the last step in a synthesis is often evaporating off the solvent before literally scraping the product off the sides of the glassware? Surely there is a better way than this.

Depending on the compound, sometimes a significant amount of material is lost this way (if the compound is firmly stuck to the glass).
 
I feel like I am missing something, google just thinks I want to know about cleaning glassware.

Any replies are much appreciated, I created an account just to ask this question.

Do you want to start learning chemical synthesis by breaking expensive lab glassware?
