| titleOfInvention | PIRIDINIUM CUTTING WATER AND PROCESS FOR PREPARING THEM |
| abstract | The invention relates to quaternary pyridine salts which exhibit a corrosion inhibiting effect in a 15% HCL medium at concentrations of 100 ... 500 ppm, as well as bacteriostatic effects, having the general formula I wherein M is 2 N is 1 ... 2, R is C 2 to C 12 alkyl, X is chloro, bromo, iodo, water-soluble surfactants having a refractive index ranging from nD to 20 = 1, 4785 ... 1.5250 and melting points in the case of the crystalline solids between 56 DEG-137 DEG C. The process for preparing the quaternary salts consists in quaternizing pyridine with alkyl (R) phenoethoxylate with 2-35 moles of ethylene oxide in the presence of an alcohol selected from ethyl alcohol obtained by the etherified alkyl ethoxylate reaction with a lower aliphatic halogen acid selected from monochloroacetic acid, monobromoacetic acid, monochloropropionic acid, monobromopropionic acid in the presence of catalysts specific (ion exchange cations, p-toluenesulfonic acid, phosphoric acid, about 1% phosphoric acid) at a temperature of 80-85 ° C, in the presence of benzene which favors the removal of the reaction water in the form of azeotrope for 2 ... 6 hours, the quaternization reaction, in the presence of an alcohol selected from ethyl isopropyl alcohol, in an inert gas preferably nitrogen gas, at temperatures of from 85 to 145 ° C and pressures of 1 ... 5 ° for 6 ... 20 hours. |
