| titleOfInvention | A kind of preparation method and application of C21-36 alicyclic diisocyanate |
| abstract | The present invention provides a kind of preparation method and application of C21-36 alicyclic diisocyanate, use dehydrated ricinoleic acid or ester and a kind of double bond-containing fatty acid or ester as raw materials to prepare unsaturated alicyclic dibasic acid, Catalytic hydrogenation reaction to prepare saturated alicyclic dibasic acid, acyl chloride reaction to prepare alicyclic dibasic acid chloride, azidation reaction to prepare alicyclic dibasic acid azide, and finally through isomerization decomposition reaction to prepare alicyclic dibasic acid family of diisocyanates. The invention adopts the acid or ester extracted from castor oil as the basic raw material, the production raw material is easy to obtain, the cost is low, the configuration of the prepared cycloaliphatic diisocyanate is single, the side reaction is few, and the molecular weight is between 300 and 500. The difficulty is small, and the same solvent is used in the last three steps of the preparation method, which is very beneficial to industrialization. The whole process is simple to operate, mild in condition, environmentally friendly, safe in production, and very conducive to industrial promotion and application. |
