| titleOfInvention | Method for preparing aliphatic isocyanate |
| abstract | The present invention relates to a high-purity production method of an aliphatic isocyanate containing an aliphatic polyisocyanate capable of suppressing the occurrence of side reactions or by-products. The method for preparing such an aliphatic isocyanate includes reacting a salt of an aliphatic amine with phosgene, and the reaction step is a first reaction of reacting with a salt of the aliphatic amine while primary inputting phosgene under a temperature of 80 to 100° C. and a second reaction step of reacting with the result of the first reaction step while secondarily adding phosgene under a temperature of 120 to 160° C., wherein the amount of phosgene that is first added is a certain ratio of the total amount of phosgene it could be |
