实验步骤: 4 moles (744 grams) of Butyloctanol were charged to an autoclave, and 0.1% of Potassium Hydroxide was added as catalyst. The autoclave was purged with Nitrogen and 16 moles (928 grams) of Propylene Oxide were added at a temperature of 150–160° C. and a pressure of 30–40 psi. Upon completion, the batch was cooled to 80° C. and neutralized with Phosphoric Acid. The resultant product, PPG-4 Butyloctyl Ether, was a very pale yellow liquid. A four-neck flask was charged with 1,224 grams of the PPG-4 Butyloctyl Ether, along with 3 moles (432 grams) of 2-Ethyl Hexanoic Acid. A catalytic amount of p-Toluenesulfonic Acid was added and the reaction mixture was heated with agitation to 160° C. until an acid value of less than 5 mg KOH was obtained. The reaction mixture was cooled to 80° C., washed with a dilute Sodium Hydroxide solution sufficient to neutralize the residual acid present, followed by washing with water. The ester layer was separated and heated under vacuum until a moisture content of less than 0.2% was obtained, followed by vacuum filtration. The resultant product, PPG-4 Butyloctyl Ether Ethylhexanoate, was a clear very pale yellow liquid having an acid value of less than 0.1 mg KOH. was added as catalyst were added at a temperature of 150–160° C. was obtained washed with a dilute Sodium Hydroxide solution sufficient by washing with water The ester layer was separated heated under vacuum until a moisture content of less than 0.2% was obtained followed by vacuum filtration
