| titleOfInvention | 2-METHYL-2,4-DIALCOXY-3-BUTENE-1-ALS CYCLIC ACETALS, THEIR PREPARATION AND THEIR USE FOR THE PREPARATION OF 4-MONOACETALS OF 3-METHYLFUMARIC DIALDEHYDE |
| abstract | These compounds correspond to formula I below. To prepare them, the corresponding acetals of 2-methyl-2-alkoxy-3-butyne-1-als corresponding to formula II are heated to a temperature of 100 to 200 degrees C with a mixture of the corresponding alcohol R * * 8-OH and an alkaline alcoholate of the alcohol R ** 8-OH. These acetals can be used in the preparation of corresponding monoacetals of methyl fumaric dialdehyde which themselves serve in the preparation of food colors of the carotenoid class. |
