Successful synthesis of 3-poly(ethylene glycol) propyl ether-heptamethyltrisiloxane from hydrosilylation of propenol polyether (HDE) and heptamethyltrisiloxane (MDHM) in the presence of nanoporous silica supported platinum (Pt/SiO2) and its chitosan modified (Pt/CS-SiO2) catalyst is reported. The highest yield obtained was 94% using the Pt/CS-SiO2 catalyst, retaining 96% of its conversion efficiency after six re-utilizations. As an agricultural synergistic agent, the newly synthesized product demonstrates significant improvements on the activity and performance of a commonly used herbicide sprayed on Alternantheria philoxeroides.
