Synthesis and characterization of glycidyl diethanolamine;

By using Amitriptyline Hydrochloride as the model drug,amitriptyline hydrochloride-chitosan microspheres were prepared by emulsion cross-linking techniques with ethylene glycol diglycidyl ether(EGDE) as a cross-linking agent.

With a tricyclic antidepressant amitriptyline hydrochloride(AH) as the model drug,Alginate as the inside layer,and chitosan as the outside layer,amitriptyline hydrochloride-Alginate-chitosan microspheres were prepared by emulsion cross-linking technique with ethylene glycol diglycidyl ether(EGDE) as the cross-linking agent.

Catalytic synthesis of 2-(2-methoxy-ethoxymethyl)-oxirane;

Polyethylene glycol bisglycidyl ether was synthesized by the reaction of polyethylene glycol(average mol weight 1000, PEG-1000) with epichlorohydrin and KOH,under the catalysis of tetrabutylammonium bromide(Bu (4)NBr).
