Condensation

I didn't take notes when i mixed the reagents, so i'm not 100% sure of the numbers. Keep in mind that this reaction wasn't done to obtain good yield, but just to obtain some product to work with. A lots of improvements can be done, especially during workup, i just wanted to get my product with the least of efforts, considering my handicap.

In a 500mL bottle, 200mL technical acetone was mixed with 100mL 20% aqeous NH3. Roughly 5g of ammonium chloride and 5g of silicagel were added, and the bottle was shaken. This was left at room temp for over 6 months, shaking occasionally. The colour change started after a week or two. Strangely, the colour was more orange than red as in the picture chloric posted [Picture 1], surely because more dilute ammonia was used. A slight pressure was released a few times. The ammonia smell was less intense as it was as the beggining.

Еще патенты нам подсказывают что нужен дегидратирующий агент.
В свете этого реакция выглядит так. Настаиваем ацетон с избытком формалина. Затем добавляем хлористый кальций или фосфорную кислоту добавляем амин и подогреваем. После пытаемся разделить что наварили
