摘要:
The Williamson alkylation of a phenolic hydroxyl group of a 4-tert-octylphenol by 2-[2-(2-chl oroethoxy)ethoxy] ethanol in the presence of potassium carbonate afforded the corresponding 9-(4-tert-octylphenyl)-3,6,9-trioxanonan-l-ol (OP3EO) quantitatively. Using powdered sodium hydroxide in place of potassium carbonate in the presence of phase transfer catalyst, alkylation of the terminal hydroxyl group occurred to give a mixture of OP3EO, 18-(4-tert-octylpheny)-3,6,9,12,15,18-hexaoxaoctadodecan-1-ol (OP6EO), 27-(4-alkylphenyl)-3,6,9,12,15,18,21,24,27-nonaoxaheptacosan-l-ol (OP9EO) and so on. Many types of OREO (k = 4, 5, 6...) could be obtained by using OP1EO and OP2EO as starting materials. The use of OPkEO with a long and single length polyethylene glycol (PEG) chain was effective for studying the environmental fate of APEOs. (C) Pesticide Science Society of Japan.
