| 31. | However, acetals, including those found in polysaccharide linkages, cannot easily become free aldehydes.
|
| 32. | Paraformaldehyde is a poly-acetal.
|
| 33. | Dimethyl acetals ( DMA ) formed during derivatization are considered to be biomarkers of anaerobic bacteria.
|
| 34. | Do I get an acetal ( assuming no cleavage ), lactone or an ether peroxide?
|
| 35. | Acetal resins are sensitive to acid hydrolysis and oxidation by agents such as mineral acids and chlorine.
|
| 36. | The aminal and the hemiaminal groups are analogous to hemiacetals and acetals with nitrogen replaced by oxygen.
|
| 37. | The original Aneros models are molded from a non-porous, FDA approved, acetal plastic.
|
| 38. | Ytterbium ( III ) chloride is a powerful catalyst for the formation of acetals using trimethyl orthoformate.
|
| 39. | Thus, methyltrichlorosilane can be used to remove acetal protecting groups from carbonyl compounds under mild conditions.
|
| 40. | In general cases, these acetals can be deprotected back to the aldehyde by using hydrochloric acid.
