Method for preparing aliphatic isocyanate |
| abstract |
The present invention relates to a method for producing an aliphatic polyisocyanate having a high purity and capable of suppressing the occurrence of side reactions and the production of by-products. The process for producing such an aliphatic isocyanate comprises reacting a salt of an aliphatic amine with phosgene, wherein the reaction step is carried out at a temperature of 80 to 100 DEG C in a first reaction in which phosgene is first charged and the salt of the aliphatic amine is reacted And a second reaction step in which phosgene is reacted with the result of the first reaction step while a second injection of phosgene is carried out at a temperature of 120 to 160 DEG C, wherein the amount of the first input phosgene is a constant ratio of the total amount of phosgene Lt; / RTI > |
