| Abstract: | 1-(2-Hydroxyethyl)-2,2,6,6-tetramethylpiperidinol, as the intermediate of HALS product UV622, is synthesized by 2,2,6,6-tetramethylpiperidinol reacting on ethylene oxide in water. The materials proportion, the mode of adding the materials and the conditions of reaction influence on the synthesis are studied. As the result, when the synthetic conditions are optimization, the GC content of the product is larger then 99%, the yield is above 90%. The operation of this method is simple, the reaction condition is undemanding, and pollute is little. |
