| Cais | Gellid defnyddio poly({{0}}ethyl-3-oxetanemethanol) fel craidd i syntheseiddio polyethers hypergangen amffiffilig (AHPs), sydd â breichiau aml-linellol poly-(ethylen glycol). Roedd yr AHPs yn berchen ar berfformiad gwasgariad da ar gyfer gorchuddio gronynnau pigment. Ymhlith cynhyrchion AHP, roedd gan AHP47 gyda 0.47 DB botensial da mewn cymwysiadau cotio. gellir ei ddefnyddio hefyd i syntheseiddio poly hypergangen sy'n canolbwyntio ar azobensen (3- ethyl-3-oxetanemethanol)[1-2]. |

| Synthesis | 3-Ethyl-3-oxetanemethanol was prepared by a modified procedure described in the literature. A mixture of trimethylopropane (1, 26.8 g, 0.2 mol), diethyl carbonate (23.6 g, 0.2 mol) and potassium hydroxide (0.1 g, 1.8 mmol) in 2 ml absolute ethyl alcohol was refluxed in oil bath at 110?C for 1 h. Then, the mixture was distilled at 110?C for 1 h. Distillation was continued until the temperature of oil bath reached 140?C. After the distillation, the vacuum was supplied for 1 h to remove the excess solvent. On heating above 185?C, the distilled materials were collected in a cold trap under vacuum and obtained >85% o'r cynnyrch damcaniaethol. 1H-NMR (CDCl3, δ, ppm): 0.80–0.83 (t, 3H, –CH2CH3), 1.61–1.66 (q, 2H, –CH2CH3), 3.62 (s, 2H, –CH2OH), 3.66 (s, 1H, –CH2OH), 4.31–4.32 a 4.38–4.39 (d, 4H, –CH2O). |
