| titleOfInvention | Method for producing aliphatic isocyanate |
| abstract | The present invention relates to a method for producing a high-purity aliphatic isocyanate containing an aliphatic polyisocyanate, which can suppress the occurrence of side reactions and the production of by-products. Such a method for producing an aliphatic isocyanate includes a step of reacting a salt of an aliphatic amine with phosgene, and the reaction step is a salt of the aliphatic amine while primary addition of phosgene at a temperature of 80 to 100 ° C. A first reaction step of reacting with phosgene and a second reaction step of reacting with the product of the first reaction step while secondarily adding phosgene at a temperature of 120 to 160 ° C. The amount of can be a constant proportion of the total amount of phosgene. |
