Amination process |
| abstract |
The present invention relates to amination processes for the preparation of polyamines. It is an object of the present invention to increase the selectivity of linear amination products and to prevent the formation of by-products or discolored by-products which can subsequently cause discoloration. According to the present method, this may be calculated based on the total yield of polyamine at the average temperature at which the amination of the first stage is considered proportionally by a time higher than 15 ° C. over the proportionally time-weighted average temperature in subsequent stages. When this is accomplished by performing a conversion of 50 to 80% by weight. |
