Synthetic example 1
[0336] At 0°C, 191 grams (g) of p-toluenesulfonyl chloride and 150 milliliters (mL) of THF were slowly added to 270 grams of polyoxyethylene phenyl ether (PH-4, Hannong Chemicals Inc.), 44 g of NaOH, 500 ml of tetrahydrofuran (tetrahydrofuran, THF) and 100 ml of distilled water in a mixed solution. After 30 minutes after the addition, the obtained mixture was stirred at room temperature (23° C.) for 12 hours. When the reaction was complete, the product was extracted therefrom, neutralized and concentrated, and then fully dried in a vacuum oven. The dried product was placed in a flask and dissolved in ethanol under nitrogen atmosphere. Next, 4 equivalents of thiourea were added thereto, and then stirred at 100° C. for 12 hours. Subsequently, a diluted NaOH solution was additionally added thereto, and then stirred for additional 5 hours. When the reaction was completed, the resultant was washed and extracted with a diluted solution of water and hydrochloric acid, the resultan...

[0340] At 0°C, 191 g of p-toluenesulfonyl chloride and 150 mL of THF were slowly added to 400 g of polyoxyethylene monomethyl ether (MPEG-400, Hannong Chemical Co., Ltd.), 44 g of NaOH, 500 mL of THF, and 100 mL of distilled water in the mixed solution. After 30 minutes after the addition, the obtained mixture was stirred at room temperature (23° C.) for 12 hours. When the reaction was completed, the resultant was extracted, neutralized, and concentrated, and then the resultant was sufficiently dried in a vacuum oven. The dried product was placed in a flask and then dissolved in ethanol under nitrogen atmosphere. Next, 4 equivalents of thiourea were added thereto, and then stirred at 100° C. for 12 hours. NaOH dilute solution was further added thereto, and stirred for another 5 hours. When the reaction was completed, the resultant was washed and extracted with water and a dilute solution of hydrochloric acid, and the resultant was neutralized, and then the resultant was suf...

[0344] 270 g of polyoxyethylene phenyl ether (PH-4, Hannong Chemical Co., Ltd.) and 100 g of succinic anhydride were put together, and then they were heated to 100° C. and reacted for 12 hours. The resultant was cooled to room temperature (23° C.), and 68 g of zinc chloride was added thereto, and then reacted at 80° C. for 12 hours to obtain 435 g of the final product represented by Chemical Formula 1-3.
