- Abstract:
- hisstudy used the chloro-methylated polystyrene-divinylbenzenecross—linked resin(ehloromethylatedbead；PS)as the basic skeleton of carrier．Firstly，polyethylene glycol，alcohol amine，diethanolamine andtriethanolamine wereused as ligands in the modification．And then，magnesium chloridewasloadedto the modified ones．Finally，the structure of IRwere analysed separately．The results indicated that the coordina— tion modification of PS of the ligandswere all realized，and the modified PShada good ability of loading the obiect—magnesium chloride．Consideringthe quantity ofgrafting，the effect ofmodification ofPEG200 is better than PEG300 and 600 etc，the capacity of loading is 3．051 mmol·g～；as for the alcamines，the effect of modification of triethanolamine is better than ethanolamine and diethanolamine．butaftermodifying by dietha．nolamine，the PS has a better ability to load the object，and the capacity of loading is 4．195 mmol·g～．The catalysts prepared were used in one·step synthesis of salicylaldehydeexperiment．Afterreusing for5 times，the activity wasstill excellent．
