Twice now I have lost my product attempting to use ethyl acetate to wash my product.
I can never get the product to recrystallize. This more recent time I had about .75g of actetasalicylic acid which I disolved in about 10 ml of ethyl acetate (yes I know I should have used less solvent.) Regardless, the instructions at that point told me to filter the product. but the mixture looks more or less homogeneous. Would typical filter paper actually trap the dissolved solids or would they bypass the filter. Regardless, I tried to remove some of the excess solvent by a very gentle controlled boil, held at 80°C. This is 50°C below the mp of acetasalicylic acid so I didn't see a lot of risk in loosing my product this way, however as best I can to I did.
So to some this all up, two questions.
1. Organic solids dissolve very well in ethyl acetate. will a sepratory funnel filter these solids at all, and of so will there be a high product loss? (assuming we are still talking about acetasalicylic acid.)
2. where was my thinking flawed in the slow heating of the solvent? How did I loose my product?
