【 摘 要 】

Unsaturated cashew phenol polyoxyethylene ether (UCPE-11, UCPE-13) was synthesized from cashew phenol by ethylene oxide addition reaction, and then hydrogenation was catalyzed at room temperature and pressure to produce saturated cashew phenol polyoxyethylene ether nonionic surfactants (CPE-11, CPE-13). The effects of catalyst dosage and reaction time on catalytic hydrogenation reaction were investigated. The optimum conditions for catalytic hydrogenation reaction were determined as follows: Al-Ni alloy was selected as catalyst at 25 °C, the dosage of which was 18% and 27.8% of the mass of unsaturated cashew phenol polyoxyethylene ether, respectively, and the reaction time was 11 h and 12 h. The structure of the product was characterized by IR and 1H NMR. The synthetic product was used in AC aluminium cleaner. The results show that the product has excellent decontamination performance. The surface of the washed aluminum parts is clean and has a metallic luster, and the washing effect is good.
