| Use | aminoacetaldehyde diethanol is one of them, used in the perfume industry, for cosmetics, tobacco, food additives, is also one of the important raw materials for organic synthesis. used in organic synthesis. |
| synthesis method | There are two main synthesis methods of aminoacetaldehyde diethanol as follows:(1) 2-(2-azidoethyl)-1, 3-dioxolane was formed from 2-(2-aoxoethyl)-1, 3-dioxolane and sodium azide under reflux of phase transfer catalyst, further reaction with triphenylphosphine/water, but the NaN3 compound is highly toxic and explosive, which is not conducive to industrial production. (2)2-(2-bromoethyl)-1, 3-dioxolane consists of a macroporous quaternary ammonium Amberlite resin (Amberlite IRA 900) with nitrite anion attached thereto. Ion exchange was carried out to obtain 2-(2-nitrosoethyl)-1, 3-dioxolane, and then catalytic hydrogenation of platinum oxide was carried out to obtain aminoacetaldehyde diethanol. The yield of this method was low. |
| production method | from the reaction of diethanol acetal and ammonia. |
