Embodiment 1
[0045] The preparation of embodiment 1 nonionic emulsifier of the present invention
[0046] Sunflower oil (1750 g), 350 g of YMER™ N-120 (0.350 mol), 725 g of PE (0.140 mol), 3.75 g of MBTO and 3.75 g of DBTO were placed in a 5-liter, 3-neck round bottom flask equipped with Heated packed condenser set at 95°C, mechanical stirrer, thermocouple and nitrogen inlet. The reaction mixture was heated at 210 °C for 8 hours and then cooled to room temperature. Phthalic anhydride (600 grams, 4.05 moles), 400 grams of isophthalic acid (2.41 moles) and 50 milliliters of xylene were added. The condenser was replaced by a Dean Stark trap with a Friedrichs condenser on top and the reaction mixture was heated at 220°C. The reaction was allowed to proceed until the acid number reached about 11.0. The degree of branching of the emulsifier was 84%.
Embodiment 5
[0052] Embodiment 5 Preparation of emulsion 1 of the present invention
[0053] formula:
[0054] Oleic acid 40%, neopentyl glycol 8%, trimethylolpropane 11%, adipic acid 15%, trimellitic anhydride 5%, emulsifier 8%, water 50%, dimethylethanolamine 2%.
[0055] Specific steps are as follows:
[0056] (1) Add oleic acid, neopentyl glycol, trimethylolpropane and adipic acid into the reaction kettle, and cover the pot;
[0057] (2) After raising the temperature of the reactor to 130-140°C within 1-1.5h, start stirring, and feed CO2 and condensed water at the same time;
[0058] (3) Raise the temperature of the reactor to 178-182°C within 0.8-1.2h, and perform esterification at this temperature for 0.8-1.2h;
[0059] (4) After the esterification reaction is completed, raise the temperature of the reactor to 215-220°C within 0.8-1.2 hours, and then keep the esterification until the reactants are completely transparent;
[0060] (5) When the reactant in step (4) is completely tr...
Embodiment 6-8
[0065] The preparation of embodiment 6-8 emulsion of the present invention
[0066] Emulsions 2-4 of the present invention were prepared in the same manner as in Example 5, except that the emulsifier 1 in Example 5 was replaced with the emulsifiers in Examples 2-4, respectively.
