| titleOfInvention | METHODINE SALT METHOD |
| abstract | 1. A reaction system for obtaining a methionine salt, having a reaction-rectification column with a weir height from 100 to 1000 mm, with a distance between trays from 500 to 1000 mm, with a ratio of the column diameter to the length of the weir wall from 1.1 to 1.3 , with a ratio of cross-sectional area to gas flow area from 1.5 to 2 and with the number of trays from 15 to 25, preferably from 18 to 20. The reaction system of claim 1, wherein the height of the overflow baffle is 150 to 700 mm. The reaction system of claim 1 or 2, wherein the reaction distillation column is a sieve tray column, a slotted tray column, a valve tray column, or a bubble cap trays column. The reaction system according to claim 3, in which in the reaction-distillation column the ratio of the total area of all holes to the gas flow area is from 0.04 to 0.08, and the diameter of individual holes in the sieve tray is from 5 to 10 mm. The reaction system according to claim 1, 2 or 4, in which the height of the overflow baffle provides an average residence time of the corresponding mixture on one tray of less than 0.5 minutes. A reaction system which further has at least one absorber reactor and optionally a subsequent reactor for the production of 5- (2-methylmercaptoethyl) hydantoin. 7. The reaction system of claim 5, wherein the absorber-reactor is a trickle-wash system. The reaction system according to claim 1, 2, 4, 6 or 7, in which zirco is used as the material of the product-contacting parts in the reaction-distillation column and / or in the absorber-reactor and / or in the subsequent reactor |
